Application of EVERSUN Sieving Machine in Feed Processing Industry

The application of sieving machine in the feed processing industry is mainly concentrated in two aspects: một là để làm sạch các tạp chất trong nguyên liệu, khác là nguyên liệu phân loại hoặc sản phẩm theo kích thước hạt của họ (bao gồm việc làm sạch các tạp chất trong nguyên liệu, phân loại các chất nghiền, và làm sạch các tạp chất trong bột trước khi hạt và phân loại các sản phẩm hạt.)

It can be said that the screening equipment is used in all aspects of the feed processing technology, so the quality of máy sàng during the processing process has a very important impact on the quality and yield of the feed. Below we will analyze these four processes one by one.

Đầu tiên, the cleaning of granules

Feed mills customarily refer to the materials that need to be crushed as granules, including grain and meal materials.

Grain raw materials come directly from the field, and the impurities contained are relatively complicated. There are mainly two types of impurities: one is impurities larger than the grain size of grain raw materials, such as stones, bắp ngô, hemp chips, Rơm rạ, hemp rope, plastic chips, vân vân. The others are soil and fine sand of small granule size.

sàng-nghiền mịn, the most common grain cleaning equipment in feed mills is the cylinder preliminary cleaning screen, which is characterized by large output, low power consumption, and high removal rate of large impurities, which can reach 99%, but it cannot remove dirt and fine sand smaller than the grain size.

Although the grain content of grain raw materials is only 0.1% đến 0.4%, in a vertical silo with a capacity of more than 1,000 tấn, several tons of silt will be deposited at the bottom of the silo and concentrated into the processing process, which will seriously affect the product quality, and will aggravate the wear of various equipment, especially the pelletizer.

Vì thế, large feed mills cannot ignore the removal of mud and sand from grain raw materials. It is recommended to use a vibrating sieving machine in grain processing to clean up grain raw materials. EVERSUN feed sieving machine uses a double-layer sieve surface with different sieve holes, which can clean up large impurities and fine sand. Ngoài ra, this cleaning screen uses a wire-woven mesh screen, and the noise during operation is much smaller than that of a cylindrical preliminary cleaning screen using a punching screen. The recommended sieve holes are selected according to the upper sieve 20 × 20 mm or φ20 ～ φ25 mm, and the lower sieve 1.5 × 1.5 mm or φ1.2-φ1.5 mm.
