The sand washing machine of XSD series, which are developed on the basis of introducing foreign outstanding technology of the same kind of products, is a kind of cleaning equipment of international advanced level for sand and slag pellets,
Working principle and Structure Of Sand Washing Machine:
1. The whole machine is mainly compositive by batardeau hoarding, rind, screw entity, reducer, and electromotor.It also has function that washing, classification and dehydration.
2. Sand washing machine inclines the arrangement according to 15°, lower part the water trough becomes the sedimentation pond by the trilateral batardeau hoarding. The spiral forehead submerges in the sedimentation pond, spiral actuates continuous rotation by the electric motor after the reduction gear, has the sedimentation pond base perforated plate to give into the clear water.
3. The sand and crushed stone enters the sedimentation pond to the feed box, in rotating under the spiral leaf blade function, it causes the sand and crushed stone tumbling and mutually grinds, simultaneously destroys a package of duplicate gravel except the cover sand and crushed stone surface on impurity the water vapor level, favor the dehydration
4. By porous panels formed by the flow of water currents, the small proportion of foreign matter will be brought to the surface spill weir plates complete cleansing. Major land surface than the particles in the surface bends plates side by creating upward spiral leaves will advance beyond the length of the water below a horizontal line suitable length away from surface water drains into another side sedimentation tanks.
5. Materials classification will not meet the standards required by small particles spill weir, the old achieved. A control method is adjusted overflow weir height and adjustment screw rotational speed.
Features Of The Sand Washing Machine
1. It is of simple structure. The bearing device of impeller drive is separated from water and materials with water, to avoid in a large degree that the bearings are damaged by being soaked with water, sand or some polluted things.
2. Being used for cleaning sand in quarries, it has many advantages compared with traditional spiral sand washing machine:
3.There is little loss for medium-sized and fine sand and stone powder. The grade and the fineness of the sand for construction after being washed can be up to the national standards, such as sand for construction and cobble and broken stones for construction. There are no other wear parts except the screen mesh.It has longer service life and little maintenance chance.
