There may be some conditions in the process of using the feed mill. What is the reason that affects the effect of the feed mill?

The factors affecting the effect of the feed mill are raw materials. The materials with higher starch content are easily vulcanized by steam. After quenching and tempering, these materials have certain viscosity and are favorable for pellet formation. For raw materials with high crude fiber content, a certain amount of oil is added. In the feed mill, the friction between the material and the ring mold can be reduced, which is beneficial to the material passing through the ring mold, and the appearance of the particles is smooth after forming. Generally, the added amount is about 1%, and the added amount is too high, which is easy to cause the particles to be loose. If more fat is needed, it can be considered to be sprayed after granulation, and is particularly suitable for producing high-energy feed. The particle size of the pulverized material determines the surface area of ​​the feed composition. The finer the particle size, the larger the surface area, and the faster the moisture absorbed by the material in the steam, which is beneficial to the quenching and tempering of the material.

From the point of view of the feed mill, the pulverization is fine, the granulation strength is high, but the steam is added more, and the squeezing is too small, and the pulverization power consumption is too high. The particle size is too coarse, the ring mold and the pressure bar are increased, and the granulation forming is difficult, especially the formation of the small-aperture ring mold is more difficult, and the material gelatinization effect is poor, resulting in high material consumption, low yield, and high particle mixing rate. Therefore, the production of livestock and poultry vocabulary is usually used. The crushed corn should adopt 2.5-3.Omm sieve plate, which can avoid the disadvantages of excessive particle size and ensure the particle size required for sufficient tempering of the feed, which is beneficial to reduce the powder mixing rate of the granule. In addition, it is necessary to pay attention to the mixing uniformity before granulation, because the composition of the feed formula is complex, and the specific gravity of various raw materials is quite different. For different formulas and different varieties, different mixing times are adopted, so that the variation coefficient of mixing uniformity reaches about 5%.
