Background
Poultry refers to artificially fed birds, primarily for the purpose of obtaining their meat, eggs and feathers, as well as other uses. Typically, the animals are of the Phasianidae and Duck families, such as chickens, ducks, geese, quails, and the like, as well as birds of other families, such as turkeys, pigeons, and various singers. The meat and egg of poultry are rich in nutrition. The meat of poultry is rich in proteins, and also in phosphorus and other minerals, as well as in a large amount of complex vitamin B. Compared to most beef and pork, poultry has lower meat fat, while poultry liver is rich in vitamin a. For small farms and domestic diets, poultry are relatively more convenient living things because of their smaller individual size.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below. The specific conditions are not noted in the examples and are carried out according to conventional conditions or conditions recommended by the manufacturer. The reagents or apparatus used were conventional products commercially available without the manufacturer's attention.
It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other. The present application will be described in detail with reference to specific examples.
On one hand, the application provides a preparation process of a feed additive, which mainly comprises the following steps:
pretreating ore raw materials, performing rotary rust removal, and then sorting to obtain rust removal powder; grinding the rust-removing powder by a pair of rollers to obtain fine powder; mixing chromium balls with various diameters, and grinding the fine powder by the mixed chromium balls to obtain a prefabricated product; and (3) carrying out multistage separation on the prefabricated products to obtain feed additives and residual products, wherein the particle size of the feed additives is 6-120 meshes.
Specifically, after the ore raw materials are pretreated, raw materials which are clean, low in water content and meeting requirements are obtained, at the moment, the raw materials are fed into a rotary mill to carry out rotary rust removal, and substances formed on the surfaces of the raw materials (influencing the quality of feed additives) can be removed through physical actions such as mutual collision, impact and friction among the raw materials, so that the expected rust removal effect is achieved. After rust removal, rust layer substances can be effectively prevented from being mixed into the feed additive, so that the use of poultry animals is influenced, and the meat quality of the poultry animals is further prevented from being influenced.
And after rotary rust removal, sorting is performed. In the application, the sorting mode is stepped jump type air separation, and the rust layer removed substances can be removed by the mode, so that the raw material for completely removing rust can be obtained. Because the mass of the rust layer material is lighter and the mass of the raw material is far greater than that of the rust layer material, the rust layer material can be completely removed by sorting in the way, and the requirements of finished products of feed additives are met.
It should be noted that in the process of rotary rust removal, the ore raw material with larger particle size can be crushed into the raw material with smaller particle size due to high-speed impact and collision, and the special crushing process can be omitted at this time, so that the process flow can be effectively simplified, the production time can be shortened, and the economic effect can be improved.
And (5) after the rust removing powder is prepared, performing double-roll grinding. The obtained rust-removing powder is uniformly pressed and ground in a roll grinding manner, and at this time, the rust-removing powder can be ground into fine powder with smaller particle size. Because the uniform pressure grinding is carried out in the roller grinding process, the controllability of the particle size of the fine powder is stronger in the grinding process, and meanwhile, the particle size of the rust removing powder can be quickly reduced, so that the expected effect is achieved.
It should be noted that the particle size of the fine powder is below 0.6cm after the uniform pressure grinding of the roller mill, and the particle size of the pretreated raw material is below 3cm, so that the particle size reduction effect is obvious, and the technological process of crushing and reducing the particle size can be saved.
And (3) after the fine powder is prepared, performing chromium ball milling. According to the application, the metal chromium balls with different diameters are mixed, and then the fine powder is added for grinding and polishing, so that the blocky or irregular fine powder can be gradually ground into rice-grain-shaped balls in the grinding process, and the expected manufacturing effect is achieved.
It should be noted here that the reason for selecting the metallic chrome balls for grinding and polishing is as follows: compared with steel balls, iron balls and the like, the metal chromium balls can not generate residual iron in the grinding and polishing processes, so that the metal iron is prevented from being contained in the feed additive, and the feed additive manufactured in the process is prevented from threatening poultry animals. The steel balls and the iron balls can generate scrap iron and/or rust by friction and collision in the polishing process, and the generated scrap iron and/or rust can be attached to the feed additive, so that the damage to poultry is generated. The metal chromium ball does not generate the phenomenon, so the safety is higher. Meanwhile, the wear resistance of the metal chromium balls is better, so that the metal chromium balls have higher use value and practical value when used for preparing feed additives.
After the prefabricated product is prepared, raw materials with various particle sizes can be separated, and the prefabricated product with 6 meshes to 120 meshes can be separated, so that the qualified feed additive can be obtained.
In the application, the multi-stage separation is performed by multi-stage cyclone air separation, and the wind speed is 18-23 m/s.
And then, continuously sorting the obtained residual products to obtain the high-grade feed additive meeting different requirements. Meanwhile, the sieved products can be respectively used as feed additives for young birds, middle birds and old birds according to the sieving particle size. Therefore, the feed additive and the product manufactured by the method can be used as feed, and the utilization rate is high.
In conclusion, the manufacturing process combines the rotary mill, the pair roller mill and the chrome ball mill to grind and polish the ore raw materials, so that the advantages of the grinding mode are achieved, the complicated grinding process can be simplified, meanwhile, the harmful substances can be prevented from being introduced into the feed by the grinding mode, and the expected effect is achieved.
In addition, in the manufacturing process, the particle size of the additive is smaller through a double-roller grinding mode, and then the raw materials are manufactured into smooth rice-shaped spheres through chrome ball milling of various mixed diameters, so that the method has the advantages of being simple in process and easy to operate, the yield of the feed additive can be improved, the utilization rate of the raw materials in the manufacturing process is maximized, and the economic benefit is higher.
In the application, the fine powder is ground by chromium balls as follows: mixing chromium balls with the diameter of 100mm, chromium balls with the diameter of 80mm, chromium balls with the diameter of 60mm and chromium balls with the diameter of 40mm, and carrying out primary grinding on the fine powder to obtain a coarse grinding product; mixing 30mm diameter chromium balls, 20mm diameter chromium balls and 10mm diameter chromium balls, and polishing the rough polished product for the second time to obtain the preform.
In detail, after mixing chromium balls with diameters of 40mm, 60mm, 80mm and 100mm, adding fine powder, polishing the surface of the fine powder with edges and corners to be smooth, and meanwhile, due to different diameters of the metal chromium balls, polishing the fine powder into a rice grain-shaped spherical structure in the polishing process, so that the expected effect is achieved.
And (3) grinding and polishing to obtain a coarse grinding product. And then the coarse grinding product is polished by metal chromium balls with the diameters of 10mm, 20mm and 30mm, and the coarse grinding product is further polished, so that the surface of the coarse grinding product is smoother, and the prepared feed additive is smooth in surface and does not damage organs such as oral cavity, throat, crop, intestinal tract and the like of poultry animals.
In the application, when the rotary rust removal is carried out, the rotary grinding rotating speed is 1400rpm-1500rpm, and the rotary rust removal time is 20s-30s. In addition, in the application, when the rotary mill is operated, the power is 500kw, and under the conditions, after the rotary mill stays for 20-35 s in the rotary mill equipment, the rust layer on the surface of the calcium ore can be completely removed, so that the expected effect is achieved.
In the application, when the double-roller grinding is carried out, the grinding pressure is 65bar-70bar, and the grinding time is 1s-3s.
In addition, in the present application, the maximum value of the pressure may be 2000pa to 3000pa, and thus, the pressure may be appropriately increased according to the actual operation situation or based on consideration of environmental factors.
In the present application, the particle size of the fine powder is 0.6cm or less. The raw materials below 3cm are pressed and ground to below 0.6cm, the pressing and grinding efficiency is high, meanwhile, the process can be simplified, and meanwhile, the expected effect can be achieved, so that the feed additive meets the qualified standard.
In the present application, the pretreatment of the ore raw material includes the following steps: ore raw materials are crushed again under the condition of drying, and the ore raw materials are separated to be less than 3cm for rotary rust removal. The water content of the raw materials can be effectively reduced after the drying, the efficiency of the separation and grinding processes is high, and the loss rate of the raw materials can be effectively reduced.
In the application, the residual products are screened and classified by a closed screen to obtain the product.
In the application, the ore raw material is calcium carbonate ore. The calcium carbonate ore is used as raw material to prepare the feed additive containing calcium. Of course, the ore with similar hardness or structure to the calcium carbonate ore can be polished and manufactured by the process to manufacture a product in the shape of rice grains.
In another aspect, the application provides a feed additive prepared by the preparation process. Specifically, the rice-shaped feed additive prepared by the preparation process has smooth surface and no edges and corners, so that when the feed additive is used by poultry animals, the feed additive can not scratch organs such as oral cavity, throat, esophagus, crop, intestinal tract and the like of the poultry animals, thereby effectively reducing infectious diseases of the poultry caused by damage of digestive systems; in addition, the feed additive is in the shape of rice grains, so that the contact area of the feed additive is large, and at the moment, the absorption rate of the poultry to inorganic elements can be effectively improved after the feed additive is eaten, and the eating effect is good.
