Sand classifier for separating mud and sand
Applycation of sand classifer
The spiral classifier is one of the equipment for beneficiation. The spiral classifier is a machine for mechanical classification based on the principle that the specific gravity of solid particles is different, so the speed of precipitation in the liquid is different. The material and powder ground out of the mill can be filtered, and then the coarse material is screwed into the feed port of the mill using a spiral blade, and the filtered fine material is discharged from the overflow pipe.
The sand classifier is used for sewage treatment.
It can remove small solids, grit, sand and fine powder in the wastewater, thereby lifting and dewatering the solids before treatment. Spiral classifier is also called sand classifier.
Introduction to working principle
It is composed of the electric motor, big and small belt pulleys, triangle belt and gear reducer. The screw sand washer adopts inclination of 15 degrees. 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 fed from porous plate at bottom of sediment pool, and the washed sand is discharged on the top side and delivered by belt conveyor.
This sand screw is muti-functions: cleaning, dewatering, and grading.
Cleaning and upward conveying at the same time.
Low water consumption.
Impellers use wear-resisting plate or polyurethane material so as to reduce the running cost.
Designed according to low volume and low investment.
