Generally speaking, spiral sand washing machine is mainly used to wash the stone powder and impurities in the mixed sand in the mechanical production line. To improve the quality of sand, with the functions of cleaning, grading, dehydration and recovery of sand washing. In this process, there will undoubtedly be some problems such as pollution and loss. LDHB new equipment screw sand washing plant from china solves this problem completely.
1.The graded materials enter the front-end double screw sand washing device. Due to the different size and specific gravity of solid particles, the settling velocity in the liquid is different. The fine particles float in the water and overflow, and the coarse particles settle at the bottom of the trough. The screw of the spiral stone washer is pushed to the upper part to discharge. At the same time, the hydraulic and mechanical forces are used to break the ore and scrub the impurities and soil on the ore Fine mud on the surface of ore is separated.
2.Then it falls into the front end of the tailings dry discharge screen, and the single direction exciting force generated by the vibration exciter makes the materials move in a reciprocating straight line and discharge from the discharge port. In this process, the moisture on the materials falls into the screen box through the screen mesh, enters the rear storage tank through the overflow device, and then is pumped into the separation and recovery device by the water pump. Under the action of centrifugal force, the qualified materials enter the tailings dry discharge after concentration The unit is dehydrated, and the rest of the wastewater is discharged into the backwater device.
The screen above LDHB spiral sand washing machine is made of high manganese wear-resistant steel wire material, which greatly prolongs the service life of vulnerable parts, and can be used conveniently and stably in various environments. It can also ensure that the material loss is minimized and the sand washing efficiency is maximized. It is suitable for river sand, machine-made sand, stone powder, weathered sand, iron ore tailings, quartz sand and other materials, especially for construction sand and road construction sand.
