Maximize the recovery of valuable fine materials from sand and aggregate production. Our equipment has a good record in handling difficult and heavy clay-bound materials, crushed stone and overburden, and removing organic pollutants.

 

Gravel cleaning equipment mainly includes the following types:

 

 

 

• Working principle: The material falls vertically from the upper part of the spiral sand washing machine into the high-speed rotating impeller, and under the action of centrifugal force, it collides and crushes with other materials flowing in an umbrella shape around the impeller at high speed. After the materials collide with each other, they collide and rub multiple times in the form of a vortex between the impeller and the casing, and are discharged from the bottom to form multiple closed loops, which are controlled by the screening equipment to achieve the required finished product particle size.

 

• Features: low power consumption, high cleanliness; good sealing structure, fully enclosed transmission device; good cleaning and dehydration effect, stable operation process; long service life, and low maintenance cost.

 

 

 

 

• Working principle: The rotation of the bucket wheel drives the sand and gravel to roll in the water, and the friction with the water flow and the bucket wheel removes impurities on the surface of the sand and gravel.

 

• Features: simple structure, easy operation; good cleaning effect, suitable for sand and gravel of various particle sizes; large output, and low energy consumption.

 

 

 

• Working principle: through the relative rotation of the two spiral shafts, the sand and gravel form a strong vortex and shear force in the washing tank, thereby removing impurities on the surface of the sand and gravel.

 

• Features: good cleaning effect and low energy consumption; suitable for cleaning fine and coarse materials.
