Sand washer equipped with sand making machine is the necessary sand washing product. It can wash stone powder and residual away from the mixed sands produced by sand making machine, which can improve the sand quality mostly.
Installation and debugging of sand washer
1. Motor should outfit rain shelter to protect equipment from creep age.
2. Sand washer should be installed on the back of vibrating screen. The rotary direction must strictly according to the requirement.
3. Check every connective bolt has been fastened before trial run.
4. Check every movable part has been lubricated well before trial run.
5. Drive belt pulley run by man before trial run. Make sure there are not any blocks in the process of working, and then user can carry on blank test. During two hours there are not any striking, pulley swinging and bearing loosen occur and the bearing temperature rise cannot exceed 35 centigrade. If the above trouble occurs, please stop machine immediately and check it.
6. The machine should be installed on the reinforced concrete. Beside this, machine user need to build a concrete sedimentation basin to deal with the waste water. The waste water can be reused after precipitation. These techniques not only meet the environmental requirement but also reduce the sand’s cost.
7. Because this machine’s working place and conductor materials are contacted with water, so users must guarantee the lead is insulated.
