Spiral Washer

alt

Coarse Material Washers are used to wash coarse sand or curshed stone and gravel to dewater the cleaned material sufficiently so it can be conveyed to storage. They are also used in some installations to assist with the removal of lignite, mica, bark, leaves and trash. They are manufactured in single and double spiral configurations with various sizes of spiral diameters and tank lengths Fine Material Washers: Fine Material Washers are used to separate water and silt from sand while dewaltering the sand. Sand discharged from a Fine Material Washer is dry enough to carry on a belt conveyor to storage.

Removal of clay and other waste materials (depending on soil mineral particles smaller than 75 microns) in the sand ond gravel mines has been one of the major problems. Conventional washing machines used in mines such as spiral and bucket sand washers have the following disadvantages. Inability to separate the fine particles, High Energy consumption and low efficient, High water consumption, The lack of uniform sand.

The new generation of washing machines

Sand washing in these machines occurs with high efficiency in water and energy consumption. Features of the system include:
Production of standard and uniform sand
The ability to separate fine particles useful for the production of concrete
Optimized water consumption
Adjustable moisture of sand content
Little space occupation
Easy interchangeable parts, resulting in lower maintenance costs
The sand washing machine is manufactured in capacities of 70, 100, 150, 200 and 250 tons per hour.
