4、工作程度：将物料从喂入斗喂入，通过提升机提升，经输料斜管进入风筛。

4. Working level: Feed the material from the feeding bucket, lift it by the hoist, and enter the wind screen through the feeding inclined pipe. The light impurities enter the fan through the air screen and the air duct, and are discharged by the fan; the rest enter the screening machine, and the large impurities, small impurities and qualified products after screening are discharged from each outlet. In this process, if necessary, the air screen control handle and the air damper control handle can be adjusted.

4, the degree of work: the material from the feeding into the bucket, through the lifter lift, through the infusion ramp into the air sieve. Light miscellaneous through the wind screen, wind channel into the fan, discharged by the fan, the rest into the screening machine, after screening of the large, small and qualified products are discharged from each exit. During this procedure, the air sieve control handle and the valve bezel control handle can be adjusted if necessary.

4. Working degree: the material is fed from the feeding bucket, lifted by the elevator, and enters the air screen through the inclined pipe of conveying material. The light miscellaneous materials enter the fan through the air screen and air duct and are discharged by the fan; the rest enters the screening machine, and the screened large miscellaneous, small miscellaneous and qualified products are respectively discharged from each outlet. In this process, if necessary, adjust the air screen control handle and the damper control handle.<br>
