Feed Pellet Grading Sieve

The common feed pellet grading sieves have two types: vibrating feed pellet grading sieve and rotary feed pellet grading sieve. Grading sieve is a necessary equipment for feed pelletizing plants. I will introduce rotary feed pellet grading sieve as the following.

Rotary feed pellet grading sieve is designed to sieve and grade feed pellets or the intermediate products after secondary crushing. It can also be used to clean the raw materials for pelletizing. The grading sieve usually has two or three sieving layers, with good sieving and grading effect. Customers can choose the suitable one according to their need.

Rotary Feed Pellet Grading Sieve

How does the Feed Pellet Rotary Grading Sieve Work? 
The screening effect is important for the quality and output of feed pellets. In order to improve the yield and reduce the power consumption during pelletizing process, some pelletizing plants use the feed pellet mills with large die diameter. Then they crush the large pellets into smaller ones. The crushed pellets should be graded to separate out the fine powder and large pellets, and get the qualified pellets at last. The rotary grading sieve is equipped with two sieve layers. The large pellets on the upper screen will be crushed again; the qualified pellets are in the inter-layer; and the powered or small particle materials under the lower screen will be pelletized again.
