Application of vibrating screen in feed processing industry

In the production of common livestock and poultry feed, a circular vibrating screen is generally used, and the sieved upper material is returned to the crusher, and the sieved lower material enters the batching bin. Generally, the mesh size is φ1.2 mm.

In the micro-grinding process of premix and fish and shrimp bait production, the material crushing size is often required to pass through the 60-80 mesh standard sieve (0.42-0.18 mm). If mechanical sieve is used, the material is too small and the material is cohesive. In the knot, it is difficult to sieving the granules, which will cause the sieving efficiency to decrease, and the amount of pulverization and pulverization to increase.

Airflow grading can resolve this contradiction. Airflow grading is a generalized sieving technique that controls the flow of material or the size of the next process by adjusting the process parameters of the airflow. The airflow, wind speed and wind pressure vary with the material type and its particle size control range.
