Description

A kind of circle high intensity granule potassium chloride fertilizer and its manufacture method
Technical field
The present invention relates to technical field of agricultural fertilizers, and in particular to a kind of high intensity granule potassium chloride fertilizer and its manufacturer Method.
Background technology
In China, most of fertilizer material of agricultural consumption is still powder product, is greatly developing the same of composite heat transfer When, powdered fertilizer is further processed into granulated fertilizer, or as BB fertilizer, or directly apply, utilization rate of fertilizer is improved, all will With good market prospects, and granulated fertilizer good physical performance, whens handling, does not play dirt, long-term storage is not lumpd, mobility Well, easily dispensed during fertilising, and can realize that agricultural machinery broadcasts fertilizer, reduces the advantages that loss, while may also function as slow releasing function, improve fertilizer Utilization rate, unquestionable fertiliser granulates are one of development trends of current composite fertilizer.The potash fertilizer in the U.S. 60% is particle potassium, The production of China's granular potash fertilizer is substantially based on extruder grain, but there are particle appearance is irregular, flowing for the potash fertilizer of extruder grain The shortcomings of property is poor.Potassium chloride is the quick-acting potash fertilizer of high concentration, and the potash fertilizer kind that dosage is more, use scope is wider.
Potassium chloride physical behavior is good, and hygroscopicity is small, is dissolved in water, is reacted in chemically neutral, belongs to physiological acidic fertilizer.Mesh Before, for China's Potassium Chloride Product mainly based on powder product, there are easily hardened etc. after easy floating dust, poor fluidity, long-term storage Shortcoming, and viscosity, poor plasticity due to powdery potassium chloride in itself, conventional production process are difficult granulating.Existing production potassium chloride Most of method of granulated fertilizer is produced using extruder grain technique, the potassium chloride particle of production, the irregular more ribs of appearance Angle, is unfavorable for carrying out fertilizer blending and dispatching；The potassium chloride intensity of extruder grain production is low, and when production is easier to produce powder Occluding device, causes production can not operate normally；And the raw material of the higher auxiliary granulating of adding proportion are needed, add and match somebody with somebody Fang Chengben, potassium content also decline accordingly.
The content of the invention
To solve the above problems, the object of the present invention is to provide a kind of high intensity circular granular potassium chloride fertilizer and its manufacture Method, changes traditional potash fertilizer manufacture method, reduces production cost, improves yield, and effectively raises granule potassium chloride and support Divide content；Have the characteristics that slow release effect is obvious and intensity is high at the same time, suitable for mechanized agricultural operation, improve crop to potash fertilizer Utilization ratio.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of circle high intensity granule potassium chloride fertilizer, it is characterised in that the fertilizer includes potassium chloride raw material, potassium oxide, glues Agent, wetting agent, acidity regulator are connect, the potassium chloride raw material is powdered, potassium oxide content 60-61%, and binding agent is half water sulphur The mixture of sour calcium and magnesia, wetting agent are ferrous sulfate FeSO4, polyethylene glycol 200 or polyethylene glycol 400, acidity adjustment Agent is hydrochloric acid.
Further, half-H 2 O calcium sulphate purity used is 98% in the binding agent, the additive amount 0.5-2% in terms of mass fraction.
Further, light calcined magnesia purity used is 90% in the binding agent, the additive amount 0.4-1% in terms of mass fraction.
Further, the wetting agent be purity be 98-99% FeSO4, one kind in polyethylene glycol 200, polyethylene glycol 400 Or several, the additive amount 0.1%-2% in terms of mass fraction.
Further, the acidity regulator is 30% inorganic acid hydrochloric acid, the dosage 0.3%-0.9% in terms of mass fraction.
A kind of manufacture method of circle high intensity granule potassium chloride fertilizer, carries out according to the following steps：
（1）Potassium chloride raw material is weighed according to dosage；
（2）The wetting agent of 0.1%-2% is dissolved in distilled water and then adds hydrochloric acid and is uniformly mixed so as to obtain mixed liquor A；
（3）By the magnesia of 0.4-1% and the half-H 2 O calcium sulphate of 0.5-2%（Purity 98%）Potassium chloride powder is added to after mixing Blended uniformly in body, obtain mixed material B；
（4）Mixed liquor A is sprayed on mixed material B using atomizing nozzle device continuous uniform, is made in granulating disc or rotary drum It is granulated in grain machine.
（5）The potassium chloride particle made is sequentially sent to dry, cooling, screening system, carrying out metering packing becomes finished product.
The beneficial effects of the invention are as follows：
1st, traditional potash fertilizer manufacture method is changed, production cost is low, and energy consumption is few, easy to spread, effectively improves potassium chloride granulating rate, Improve industrialized production yield.2nd, potassium chloride particle intensity produced by the present invention is high, mean intensity 35-45N, granularity 2.5- 4.75mm, it is uniform in size, physical behavior is good, good flowing properties, be not pulverized easily, stability it is good, can directly be applied as fertilizer, have There is certain slow release, the blending of BB fertilizer directly as the raw material of bulk blended fertilizer, can also be carried out.3rd, suitable for mechanization of agriculture Operation, improves utilization ratio of the crop to potash fertilizer, while also contains certain moderate-element, plays the role of getting fat synergy.4、 The potassium oxide content of granule potassium chloride is up to 57.9-59.7%, can be used for preparing the highly concentrated degree type BB fertilizer of high potassium, also can individually make With applicability is extensive.5th, production technology is easy, a variety of granulation modes is applicable in, using traditional compound fertilizer prilling, such as disk Comminutor or roller pelletizer.
