[Related References] This application claims priority to the following two cases. The United States Invention Provisional Application No. 6 0/1 32, 5 6 9 has an application date of May 5, 1999. And 60/132, 6 81, the application date of which was May 5, 1999. [Technical Field] The present invention relates to a method for granulating fertilizer (compos t), and more specifically, to a method for producing high-quality fertilizer granules and multi-component fertilizer granules for use in the field of fertilizers. [Technical background] Granulation technology is a mature technology field, and recent important improvements can be found in US Patent No. 5 460, 765 owned by Derdall et al., The date of issue is 1995 October 24. And, the follow-up US patent No. 6,013,209 of Phinney, the date of issue of the certificate is January 11, 2000.戍 ... 'About the patent case of Dedal et al.' This is a disclosure to improve this technology, which shows that an ultra-fine (-200 mesh) has not caused the nucleation of the powder: Yes, but it caused the adhesion of the material A large round pellet is formed. This process is not unlike the growth of the well-known snowball. The technology invented by Dedal et al. Clearly provides an excellent process control which effectively contacts the particles with the binder to grow larger. As a result, the usual use of 5% or less of the binding agent additive 'has approximately doubled this amount. Evidence shows that if the amount of the binding agent can be reduced, the amount of granules supplied can be increased. According to the spoon changing section, an improved pellet or granule is provided. The process established by Dedal et al. Is to use a very large number of crystals.

523394 V. Description of the invention (2) (crystal) or seed, a major improvement in this technical field in one step θ forming. Although this acre is connected to Jiang Guzu's private property, the dagger is not intended to be formed in the container. If a mixture of materials includes a feed to pill 'and the water damage is provided by a pre-wetted mixture, it may have a nucleating agent. Then this material can be used directly in the container. It contains powdered feed material to grow into a pellet. Et al. Have significantly improved the granulation technique by demonstrating that the material can be granulated ' and provide a sub-material that acts as a core to form: pellets.前 Before the applicant's hard work in research and development, Dedal et al. Have effectively taught this new technology ' and ' when the seed material can be used, it is an extremely effective granulation forming process. Such granules have a clear core at the center. In this technique, everyone knows that any particles larger than +150 mesh and -100 mesh will cause over-nucleation in the container, which will inevitably cause the particles to stick together into many clusters. . As a result, in order to obtain a pellet having sufficient strength, 4% to 10% of a binding agent is generally used, so that the material has a proper cohesive force, and then becomes a strong pellet. Dedal et al. Clearly teach that if the seeds used exceed a predetermined size, there will be stability problems in the process. In short, Dedal et al. First provided the process for granulating powdery materials. The Fenni's chrome-discovering technology is further improved than the original patent of Dedal et al. In Fenni's patent, he found that if a nucleating agent with a size distribution between -35 and 150

Page 5 523394 5. Description of the invention (3), will grow and contain the same materials as the final product, and its size distribution is about -8 to +4 sieve. The difference between the patents of Dedal et al. And Fenni's patent is that in Fenni's technology, 'a seed is not needed to achieve the purpose of granulation. This seed can be formed into a seed by using an initial nucleating agent in the flour, and the seed will continue to grow during later granulation. This leads to a significant improvement in the quality of the final product. One of the main advantages is the strength of the pellets and the growth of a uniform material for the seeds. The effectiveness of the nucleating agents used is extremely small. Compared to granules made according to the patent of Dedal et al., Granules made according to the patent of Feney have no core. That is, the granules made according to the Fenny method have a uniform and continuous cross section. According to this, for each granule or pellet, it contains a higher amount of feed. The patents of Feney and Dedal et al. Both have a deep introduction to the granulation technology of materials with high bulk density. In these examples, sulfur is used as an example for granulation. Sulfur has a fairly high bulk density, which is between 30 and 35 pounds per cubic foot. This bulk density represents a particle size between 180 and 300 mesh. At this bulk density, there is sufficient quality to allow the granulation of the product. It can also be found that this is not applicable to all materials. Problems can arise when this bulk density decreases significantly, such as from sulfur to fertilizers. Granulation of fertilizer materials is very complicated. When the fertilizer is in a powder form, it is extremely light-weight ' it is water-resistant, and due to the effect of static electricity ' The bulk density of the fertilizer is between about 20 and 25 pounds per cubic foot, and it's about the size of granules between 2400 and 400 mesh. According to the state of powder

Page 6 523394 V. Description of the invention (4) and the nature of fertilizers' As far as the conventional technology and the technology taught by Fenni and Dedal et al. Are concerned, if valuable agricultural grain compounds are to be granulated, then Substantial changes must be made. The granulation method of fertilizer has been seen in the conventional technology. For example, the seed is protected by plating, or by other coating (or coating), until now, it needs to be germinated. A typical previous case in this technical field is US Patent No. 3,905,796, issued to Ghelfi in 1975. This case teaches a fertilizer based on dehydrated natural fertilizers. Among them, a uniform and durable slurry (pu 1 ρ) was granulated. The US patent discloses a natural fertilizer system for squeezed livestock. 55% of the water is broken up into smaller steps to discuss the addition to the fertilizer. And found an interface activator, how to solve these problems Davis (D av artificial fertilizer (ferti product method. The source 'It is put into a mixed mud system is No. 4, 082, 532, 1978 4 A certificate was issued on April 4 for the method of exposing livestock natural fertilizer pellets, in which the mixing becomes a slurry, which includes a weight ratio of approximately. This material is extruded through a stranded rope, and then further In this case and the previous case, there are no agricultural additives in the feed, and only a slight mention is made that when the pellet material becomes a dry powder, the material is humidified without L and t. And These previous cases have not been taught to achieve the purpose of granulation.

This is transported to a desiccator and dried under vacuum

523394 V. Description of the invention (5) After the absence of ', it is cooled to produce' grained or 1 half-grained artificial fertilizer, which is covered with a sub-core and covered with another layer of nutritional crystalline layer. In U.S. Patent No. 5,72 5,630, issued to Roberts et al. On March 10, 1998 'It is a fertilizer as described previously and a dried Granulated fertilizer. The granulated fertilizer comprises a C1-C6 alkanoic acid or a salt of the compound and is added to a dry carrier to form a granulated fertilizer. This is an early process, but it does not provide a granulate with uniform auxiliary or auxiliary fertilizer compounds. For other previous cases of artificial fertilizer / seed coating technology, US Patent No. 4,779,376 'October 25, 1998, discloses a coating method that encapsulates plant seeds in a saturated water solution. In a hydrogel capsule, Johnson et al., A patent issued in U.S. Patent No. 3,648,409, March 14, 1972, discloses a herbicide delivery process in order to Make this product. This disclosure discloses a herbicide-resistant wafer, which is a mixture of vermicuHte with a water-soluble nutrient binding agent and active wood charcoal, which is finally compressed into a predetermined shape. In this example, It is a wafer. Other previous cases are generally related to coating or coating technology, such as U.S. Patent Nos. 4,759,151, 5,849,320, 3,950,891, 3,950,152, 5,435,821 and 3 , 651,772 ° The previous case, whether alone or in combination, did not provide a method for granulating fertilizer powder materials. The fertilizer may include auxiliary fertilizers, time-release materials, or other suitable conventional additives. Also, it ’s not actually taught

At the same time, a granulated product is provided, which has the characteristics that the conventional techniques reviewed have not been able to maintain the required characteristics, such as round balls, sub-packages in $, and still the dimensions and so on. We have always hoped to have the strength and dissolution of the seeds, and these fertilizers include fertilizers that directly strengthen the soil with a product or a smaller sieve ruler: ί :; shape: fertilizer material, which is -150 No., this fertilizer material can be the same fertilizer as the aforementioned two-two fertilizer material.

No water resistance problem [Industrial applicability] The present invention is in fertilizer technology i Jb I Q [Objective of the present invention] * It has industrial applicability in the field. One aspect of the present invention provides an improved method for pulverizing fertilizer granules without nucleating agents and other starting materials. This ^ ^: example, another-the purpose is to provide a coating method, # by granulating; J as the killer seed wrap to achieve the purpose of wrapping seeds. Another objective of the present invention is to provide a method for granulating fertilizer, which is characterized in that the method includes the following steps:… for a dry powdery fertilizer, in which 90% of the size distribution is less than −150 sieve Net; 'forming a moist mixture consisting of dry powdery fertilizer and moisture-containing binder, the mixture containing 11% by weight of water; mixing the mixture to a level sufficient to dry the powdery fertilizer The water resistance is eliminated, so that the dry powdery fertilizer absorbs the water in the binder and forms a flowable composition;

V. Description of the invention (7) By contacting the mixture and adding additional binding agents and -interfaces, tongue agents 'in a container, the mixture is granulated into a plurality of 2 / things; and' form fertilizer particles The size distribution of the object is between No. 3 and No. 2 through & net. It is advantageous that, when heated and dried, the fertilizer has been disinfected and killed-囷 'Therefore, odor and pathogenic sources are not a problem. It also allows this fertilizer to be 'made from any form of source, including animals, plants or both. Regarding the water resistance of the powdery fertilizer, it was found that if a weight percentage of free radical water of up to 10% was provided in the container, the manufacturing process would be eight lines and produce granules. In this case, an important method of the present invention is to reduce the surface tension of the fertilizer by adding an interface activator, and allow the granulation process to be directly generated in the container in the absence of a nucleating agent or other initial materials . This process can effectively achieve the purpose of fertilizer granulation. The use of nucleating agents has been disclosed in the prior art to achieve "drying" of the feed material. This is also discussed in Fenni's U.S. patent. This situation is also seen in Dedal et al. After the further improvement of Fenny, especially referring to the publication information of PCT Application No. PCT / CA9 9/0 0 3 0 0 (International Publication No. WO / 9 9/5402 9 published on October 28, 1999 It has been found that granulation in a container is reachable by providing a wet mixture (mixture_ including water, supplies, and interface activators), and contacting the wet mixture in a container. This also achieves the formation of granules directly in the container in the absence of nucleating agents or seeds. That is, the granulation can be-to delete the step of forming a child.

Page 10 523394 Depending on fertilizer density and. For the cooperative drying method, this is because, in a nutshell, the depleted nucleation standard 9 is used. In addition to Dal, etc., the method is mainly applicable to fertilizers. Compound. The characteristics of the medium-speed conversion rate and other properties are simplified, especially the fertilizer. This material is powdered fertilizer. For a water-resistant agent and a comprehensive understanding of fertilizers, there is no solution to solve fertilizer problems. The nature and use of the fertilizer is more likely to be allowed. For example, after the Dadalization, the container will be decanted. The designer of the fertilizer process will be mentioned that the fertilizer may be directly granulated in the container, for example. The inconvenient beta side cannot be satisfied by the operation of a shuttle agent. For materials that are not beneficial to a nucleating agent and have quasi-water resistance problems, and materials that have these characteristics, but cannot effectively granulate into a child, it is difficult to achieve marketable properties. Gao Tong. The large size ° is larger in order to wait for people to reach a slope and 5. Description of the invention (8) As mentioned above, new problems are encountered. The bulk granulation process is complicated in the aforementioned PCT (specially considering the pre-formation of other existing seeds, prepared in the size of a nucleating agent. Part of the original electrical effect is troubled, it is originally a self-pill, especially a grain that is not affected In the case of intermediate-range experience in this example, everyone can agree that Dejin's technology β is eliminated because of these topics, and its properties are made if the fertilizer granulation process to be formed is made on the golf course. For the larger grain method, the material is at the container point. This depends on the container selection and the practical problems of depth. Most of the methods: The method has been changed to apply to fertilizers. Granulation is determined by the time required to balance the enemy ’s power with the appropriate size and other parameters of Fener ’s formula. Page 11 523394 V. Description of the invention (9) In this case, if necessary, it can be combined with a The second container is used for material growth. Accordingly, according to the purpose of an embodiment of the present invention, a method for granulating fertilizer is provided, which is characterized by including the following steps: Powdery fertilizer, 90% of which has a size distribution smaller than -150 mesh; Forms a wet mixture consisting of dry powdery fertilizer and moisture binder, the mixture contains 11% Water content by weight; mix the mixture to a level sufficient to eliminate the water resistance of the dry powdery fertilizer, so that the dry powdery fertilizer absorbs the water in the binder, and form a flowable synthesis By contacting the mixture and adding additional binding agents and a surfactant, in a container, the mixture is granulated into a plurality of granules in a first stage, the size of the plurality of granules It is distributed between the No. 3 to No. 12 sieve, and at least includes a part of the size between No. 8 to No. 12; In the second stage, the mixture and the binder are contacted again; and fertilizer granules with a size of -3 to +8 are formed. In some cases, it is' desired to produce a size larger than that described for the purpose described. Granules of 4. For example, from a process standpoint, 'will_ 3 to + No. 8 mesh size granules grow even further to 0.5 inches or larger. This can be achieved using a drum granulator. Similar early-stage operations such as additives for binding agents, surfactants, Mixing with the binding agent, etc., can be observed in the drum

Page 12 523394 V. Description of the invention (ίο) The growth of 0.5-ying leaf granules in the container. For those who are familiar with this technology, the special odor of the binder's interface activator added to the granulated container has no effect. The key point is that the material in the container must be supplied with an appropriate interface activator. In order to effectively bind the granules and the binder together into the fertilizer mixture. At this time, the interface activator of the binding agent can be mixed and added to a weight ratio of 11%, or added simultaneously and separately. Of course, it can also be modified by those familiar with the technology. A further application of the present invention is that this technology has touched the agricultural grain seed coating technology, that is, another object of the invention is to provide a method for coating a grain seed with fertilizer and turning it into a pellet. The method comprises the following steps: providing a dry and powdery powdery fertilizer, wherein 90% of the size distribution is less than -150 mesh screen; providing a plurality of maggot seeds; forming a dry powdery fertilizer and A moist mixture composed of a moisture-containing binder, the mixture containing 11% by weight of water; mix the mixture to a level sufficient to eliminate the water resistance of the dry powdery fertilizer, and absorb the dry powdery fertilizer Moisture in the binder and form a flowable composition; provide a granulated container; contact the container with the cereal seeds; contact the container with the mixture; in the container by contacting the mixture With that grain seed will

The problem is' Because these seeds are very light, they are often scattered in the air to the intended The location, in this way, has caused early crops to be planted among the farmers. In addition, in many countries, residents no longer like to use the "vacant living", Chongdan-based additive farming. Spoon seeds are protected ... when the seeds are planted, the two kinds of seeds "Second = There is an interval between various seeds, and one of the seed coatings provides a covering fertilizer, so it can also be used as a seed fertilizer, more Can be arsenic II, long as needed. In addition 'add other appropriate materials, will be the following 1 j ^ into a desired product.

It should not be placed too close to the seeds, because the penetration of salt is too strong, and the seeds cannot germinate. The fertilizer's / -1 1 'value can be absorbed without changing the osmotic pressure. The single advantage is that 'this method will reach more than 30% of the granules with ^ 0 ions. In addition, the coated seeds automatically provide seed nutrients, and the size that will be wasted is (No. 6 to No. 8 sieve) small seeds, which is not good when planting. This coating also determines the flowability of the seeds, which makes handling and shipping easier. 50%. Excessive seeding (〇Ver Seeding), which is typical of drought relief, may be as high as you.

Before explaining the present invention in detail, it is important to note that regardless of the plant's fertilizer, it is necessary to use a container as a fertilizer for powdery materials with extremely low bulk density of about 20 to 25 pounds per cubic foot. Granulate, feed ^ 4 and for is presented. From the standpoint of static electricity, powdery fertilizers are inherently fibrous, and powdery fertilizers have considerable water resistance, making them difficult to compress or self-repulsive. To have the solution to the above complex problems, using containers as fertilizer granules, especially for the bulk density of fertilizers, cannot be formed on a container in a dynamic manner. Humidification, growth, and curing of materials cannot be ignored, and it is known that the technology cannot achieve the present invention. It has been found through experiments that if the bulk density of the material can be increased to a sufficient value, it will form pellets and sisters, and grow with other fertilizer materials or auxiliary artificial fertilizer compounds ::. Forming a mixture of powdered fertilizer, a suitable interface activator, and a knot is a successful solution. This introduction

Chemicals are used to reduce the surface tension of fertilizers to allow moisture to be combined with the fertilizers. Once mixed, this mixture can be further granulated in a container with the same additional binder. Therefore, the addition of two additional binders allows it to be applied by conventional spraying devices.

For example, according to the process shown in the first figure, granulation. The present invention can be achieved. Please refer to the first figure, which shows that granules of fertilizer can be formed. The standard allows most fertilizer granulated products to be salt, soda ash, sulfur, bell magnesium, potassium chloride, sodium vaporized and ammonium vaporized meals), and other substances. The overall schematic diagram of the granulation method. The number 10 represents the place where the fertilizer is added. This technology molding ’includes a variety of sulfuric acid, kaolin

After the fertilizer is added and the binding agent is added, it enters a pulverizer 2 to change the entered object into a powder, and its 90% size distribution is less than -150. Most injuries-200 mesh screen. The pulverizer I? Can be a graded pulverizer or a sweeper type pulverizer or other suitable-once powdered, the fertilizer stream is generally labeled with =; led to a closed collection The collector, represented herein by the reference numeral 16, includes a bag-like chamber 18 for collecting dust. The collector 16 also includes a suitable valve 20 to regulate the entry of dust into a container 22, which is connected to a mixer 23 to enable mixing with the binder (approximately 5 §% solids).

In this embodiment, the binder is a concentrated lignosulfonate solution. After mixing for a short period of time, this mixture is formulated to have granulating properties. This dry powdery fertilizer is usually water-resistant, and it can be observed that it has become hydrophilic because the water in the binder is deliberately or transferred into the fertilizer. And the binder solids are dispersed in this powdery mixture. This results in a significant increase in its bulk density in order to provide a flowable powder.

523394 V. Description of the invention (17) After coming out of the mixer 23, the mixture which has been added with water in advance is transferred to a feeder 24. Moisture and interface activators can be added through a carrier known in the art, and this carrier is designated 26. It can be seen that the weight proportion of water in the mixture has increased to 11%. This part should not be confused with the water in the bonded hydrate | This moisture means free water, which is very important for granulated shoes. Once the correct moisture is obtained, the mixture will pass through a container type carburetor 28. In order to form granules, additional binders or interface-activating materials can be added, such as aerosol gel (aeros01). The aerosol adhesive is sprayed by a suitable atomizer or moisturizer. This aerosol glue combines the same material as fertilizer powder, or go to B. ★ ^ ^ ^ ^ μ material or 疋, this binder can choose different artificial fertilizer compounds, which can be dissolved in the solvent of the binder in. The grainer type granulator 28 includes an upper scraper 34 and a lower scraper 36. This binding agent can be added at any position between 12 o'clock and 15 o'clock in the direction of & @ ρ, 々々〇 position & By using an interface activator, the surface tension of the fertilizer can be reduced + the surface tension of the knife is water-resistant, so that the bulk density of the target material can be increased by "^., &Amp; j Μ increased, and humidification, Growth and curing. Suitable interface activators include carbon C4-C8 sulfonic acid (sulfonic = ldS,% acid, sodium succinate), and others. 1 surface activator can be used together with the binding agent When mixing or adding the correct free water in this container to obtain a weight ratio of 10%, the container will remain in a stable state. The typical size of the product formed by the trough 28 is between 3 and 3. No. 12 sieve

523394 V. Description of the invention In the meantime, this product is introduced into a dryer 39 and dried. For example, the dryer 39 may be selected from one of a Carrier dryer, a tray dryer f, or a Rotorou dryer. The product produced by the drying room 28 is transported to the drying room 39, which can be achieved by a suitable drive belt, which is indicated by reference numeral 41 throughout the text.

^ After the product leaves, the dryer 39 passes through a mobile body 4 2 and then passes through the appropriate screen group 44. The screen group includes 3, 8 and -20 screens. The purpose of setting this sieve part 20 is to send it to the pulverizer 12 for recycling operation. This recirculating stream is designated by the reference numeral 46. Oversized lumps are crushed by, for example, a Fritz mill, and then returned to container 28. The product between parts 3 to 12 is the final product and is removed from the screen group 44. This final product is labeled 48. Any ash remaining in the dryer 39 can leave the dryer 39 through the line 54 and be loaded into a bucket 56, and what is collected in the bucket 56 does not enter the bag-shaped chamber 18 through the line 58, It is through the pipeline 60 to enter the fertilizer adding place 10. The finer materials or ash entering the bag-shaped chamber 18 can be further supplemented, such as humidification and scraping, that is, the number 60 shown in the first figure. Other examples belong to those skilled in the art. D. Regarding the container 28, it can adjust the angle and the rotation speed. In addition, the known advantages are not only changing the horizontal angle of the container, but also tilting the container so as to enhance the efficiency of the granulation process. As for the specific angle of the inclination or the specific angle of the horizontal, it depends on the rotation speed and the size of the product to be granulated. ^ As for the second embodiment of the present invention, as shown in the second figure, it is a possible

523394 > Description of the Invention (19) Circuit of the line. In this embodiment, the one bucket device 32 is caused by the following sources: for example, canary seeds, canola seeds, and the like. About size points. ^ J * After the seed of the crop is coated with fertilizer, it becomes a useful size distribution of the product used-generally between 6 and the mouth of the gas product. The extremely useful final product is, The seeded final minimal rabbit Qj includes a single seed. This percentage can also be increased to 2 = 90% by increasing the seed volume in the container. This part is particularly useful in the industry, that is, from the perspective of the size distribution of the final product, waste has been minimized, and excessively concentrated seeds are no longer intended to be solved:. In agricultural technology, over-concentration of seeds has not covered the major issues, and it has also led to additional costs in this industry. On the other hand, the bucket device 32 may include an artificial fertilizer material, such as ammonium sulfate, and its size distribution ranges from -35 to +150 mesh, and is a nucleating agent. This increases the granulation process and results in the formation of a compound fertilizer and two granules, which have an artificial fertilizer at the core. As mentioned above, the material of the fertilizer can also include many different materials. See FIG. 3 in the next figure, which shows another embodiment of the present invention. f In this embodiment, two containers 28 and 30 are used, which respectively form the first-stage compound and the second-stage larger pellets. The mixture, as previously described, is directed to a small container 30 to form a sieve having a size between 3 to 12 /, and a portion of the mixture is between 8 to 12 in size. This mixture is transported to a container 30 by a feeder 33. The container 30 includes scrapers 38 and 40. This +8

V. Description of the invention The particles of No. 20 sieve and No. 12 sieve pass through the container No. 28 and are treated as shown in the first figure until the size distribution reaches -3 to + No. 8 sieve So far. Of course, if necessary, this size distribution can be further enlarged, that is, by directing the granules produced at 48 places to a drum granulator 62, so as to further increase the size of the material to 0.5 inches. Pills. In this drum granulator 62, it is obtained substantially in accordance with the container processing procedure described above.
