1. It has good cleaning effect and high impurities removing efficiency. The efficiency of removing big impurities is higher than 99%. The big impurities do not contain complete granules or clean materials;
2.Horizontal cantilever screen cylinder is adopted. Screen cylinder is divided into feeding section and discharging-sieving section. The use of different combination of screen holes can get ideal sieving efficiency;
3.Adverse feeding type is adopted. The discharging section of screen cylinder is fitted with screw, which increases actual sieving length, reaches sufficient sieving effect and effectively prevents impurities from carrying clean materials;
4.The structure of inner sieving and outer brush cleaning is adopted. The fiber impurities and paddy straw are discharged in the shape of ball through guide screw and are cleaned automatically and reliably;
5.It has low power, high capacity, smooth and reliable running, convenient screen replacing and maintenance , compact structure and less space covered;
6.It is widely used for pre-cleaning of raw materials in the industries of feed, oil, flour, rice milling, grain warehouse, food, etc.
