Step 1: Washing
The electric motor runs slowly with the impellor after decelerated by the belt, decelerator and gears wheel. The sand and stone flow into washing launder from feeding launder, rolls with the impellor, and grinds each other. The impurity covering the sand is washing away. At the same time, add more water, the strong water flow will take away waste and some low-weight wastes from washing launder. Through the above process, the washing function is finished. The clean sand and stone is lift up by vane. When it goes up slowly, the water begins to drop through the mesh and fall back in the washing launder.
Qualified sand is shoveled to the dewatering screen directly. This dewatering screen sieve is made of PU polyurethane material, no blocking, can bear high temperature and corrosion resistance is high, service longer working hours. From this step, wet sand moisture can be highly reduced.
Step3: Fines recycling
Waste sand water is extracted by slurry pump into high pressure sediment separator, fine sand 0.16-3mm is sprayed onto polyurethane screen also for de-watering, the waste water is back to return box and flowing out.
1. Recycling 0.074-3mm fine sand;
2. High productivity and 95% fine particles in the material can be recycled;
3. Solving cleaning problem of sedimentation tank and improving economic performance at the same time.
Overall dimension (mm)
The screen is composed of thick steel plate and the mesh is punched.
Polyurethane Lining, for recycling 0.074-3mm fines.
The thickness is 40mm, fixed by bolts and it works over 18 months.
Three phase asynchronous motor
With the advantages of high overload capacity and mechanical strength, suitable for short-term or intermittent cyclical duty, frequent starting, braking and significant vibration and impact.
