The grinding of feed ingredients is a very important part of feed processing. The grinding can increase the total surface area of the raw material particles per unit mass, increase the solubility of feed nutrients in the animal digestive juice, and improve the digestibility; at the same time, the particle size of the crushed raw materials is important for subsequent processes (Such as granulation, etc.) the degree of difficulty and the quality of the finished product have a very important impact.
The size of the crushing particle size directly affects the production cost. When producing powdered compound feed, the power consumption of the crushing process is about 50% to 70% of the total power consumption. The smaller the pulverized particle size, the better for animal digestion and absorption, and the better for granulation, but at the same time the power consumption will increase accordingly, and vice versa. Properly mastering the crushing technology and selecting the appropriate crushing models are issues that cannot be ignored in feed production.
