Washing & Classifying

Spiral Sand Washing and Recycling Machine


In order to solve the problem of cleaning difficulty caused by the limitation of the site and other conditions, the market needs a kind of equipment with the small floor area, simple operation, large handling capacity and better cleaning effect.

LDHB put into production the double screw screen washing machine to solve the above problem. The screw sand washing machine is a multi-function sand washing equipment with the functions of washing sand, sand material dehydration and recovery, etc. It is composed of a spiral sand washing machine, dehydrating sieve and cyclone.And the machine is widely used in mining, aggregate processing, pile driving mud, river dredging treatment, urban construction waste incineration treatment, ceramic raw materials processing, silica sand production processing, various metal ore tailings treatment and many other industries.

Working principle

The materials enter the front double screw sand washing device for graded cleaning, the qualified materials enter the tailings dry drain device at the rear of the machine for dewatering. The remaining wastewater (including some qualified materials) in the screw sand washing device enters the rear end storage tank through the overflow device and then is driven into the separation and recovery device by the water pump. After the classification concentration under the action of centrifugal force, the qualified materials enter the tailings dry discharge unit for dehydration, and the remaining wastewater enters the backwater unit for discharge.


1. The vibrator is used to provide the source, with a large excitation force and high output. The output per hour can reach more than 300t, and the operation can be continuous.
2. Combined with screening and cleaning, short production cycle, small floor space, easy to produce and process.
3. The slurry pump and the cyclone are connected together to form the backflow of water, which can save water consumption.
