(1)Introduction

XL series sand washer can wash and separate the soil and foreign material in the sand. Its novel structure, adjustable overflow dam baffle and reliable arrangement can make sure the result of wash. It is widely used to wash, classify, rid impurities, and choose the coarse from the fine in the industries of highway, hydropower, construction, and so on. It is better to wash construction and road sandstone.

 

(2)Working Principle

Tilted installation forms a sedimentation tank at the machine end. Screw head enters into tank. Screw be driven by motor and reducer and cleaning water enters into sedimentation tank from the bottom. Thus it completes the three functions of washing, dewatering, classifying.

Washing: Sand enters into tank and grinds under the rotating screw effect. The impurities covered on the sand be removed and sand moisture layer be damaged for easy dewatering. The cleaning water injected from machine bottom forms a flow and it sends the fine particles and impurities to the surface, then finally be overflowed from weir.

Dewatering:  Heavy sand sinks into tank bottom and in the side of curved plate. Screw pushes sand up and forward. The excess water be removed. The removed water flows into tank through gutter from other side, while the dewatered sand be discharged from the tank top.

Classifying: The classification function is accomplished by overflowing fine particles. We can control it by adjusting weir height and screw speed.
