Brief introduction

Base on years’ experience and technology, LSX screw sand washing machine is designed to provide bigger capacity and higher cleaning level than traditional sand screw. It is also called “stone washing machine” as its input material size is at most 30mm.


Now LZZG screw sand washer is widely used for cleaning materials in quarry, minerals, building materials, transportation, chemical industry, water conservancy and hydropower, cement mixture station and so on.


Working principle

LZZG screw sand washer is composed of the electric motor, big and small belt pulleys, triangle belt and gear reducer. The spiral sand washer adopts inclination of 15 degree. Under the water tub, three weir plates form the sediment pool. The spiral head is immersed in this pool, and the spiral is driven by electric motor through reducer rotating continuously. The fresh water is feeded from porous plate at bottom of sediment pool, and the washed sand is discharged on the top side and delivered by belt conveyor.



1. Three functions: cleaning, dewatering and grading.
2. Cleaning and upward conveying at the same time.
3. Low water consumption.
4. Impellers use wear resisting plates or polyurethane materials so as to reduce the running cost.
5. Designed according to low volume and low investment.
