Introduction of Spiral sand washing machine:

The equipment is suitable for washing, classifying and removing impurities in metallurgy, building materials, hydropower and other industries, and it is suitable for washing of fine and coarse-grained materials. It is suitable for building sand and road building sand and stone. The spiral sand and stone washing machine has the advantages of reasonable structure, convenient maintenance, large processing capacity, low power consumption and high cleaning degree. The new sealing structure, fully enclosed oil bath type transmission device and adjustable overflow weir plate ensure that the series of products are durable, with good cleaning and dehydration effects, and the fine-grained products are stable.


Working process of screw sand washing machine (stone washing machine):

The materials fall vertically from the upper part of the machine into the high-speed rotating impeller. Under the action of high-speed centrifugal force, the materials collide and crush with the materials around the impeller in the umbrella shape. After the materials collide with each other, they will form eddy current between the impeller and the casing for many times, collide with each other, rub and crush for many times, and discharge directly from the bottom to form a closed-circuit multiple circulation, By the screening equipment control to achieve the required product size.

Working principle of screw sand washing machine (stone washing machine):


The screw sand washing machine (stone washing machine) drives the impeller in the water tank continuously to make circular rotation in the water tank through the drive of motor and reducer, so as to stir, flip and wash the sand and stone or slag particles in the water tank in the water, and make the water receiving materials dehydrated in the impeller and then discharged.


Spiral sand washing machine (stone washing machine) features:

1. Sand and stone washing operation can prevent blocking of ore bin, chute, funnel, crushing and screening equipment, and reduce the processing capacity of crushing and screening equipment. When the blockage is serious, the production can not be carried out normally.
2. Some ores, such as sedimentary manganese ore, Apatite Ore, iron oxide ore, etc., can be obtained by enriching useful minerals through ore washing.
3. The quality of limestone for smelting can be improved by ore washing.
