◆主要用于粮食加工厂及饲料厂的颗粒物料去石。通过风幅的作用使物料与石子自动分离，二者又在往复运动筛板的作用下向相反方向运动，从而达到的去石效果。该机能直观的调节风量，带有压力表监控吸风罩内的压力状况；附带的照明灯管能使机内物料运动状况清晰显现。

◆Mainly for the food processing factory and feed mills of granular materials to stone. By the wind of the role of material with stones automatic separation, both in reciprocating motion under the action of sieve plate to the opposite direction, so as to achieve excellent 

stone effect. The machine can adjust the air flow and intuitive, with a pressure gauge to monitor the pressure of the suction hood conditions; Accompanying the lighting tubes can make the machine within the material movement status clearly revealed.
