The status of artificial sand washing at present most of the existing artificial sand production lines are utilizing wet production process. No matter what the type of sand washing machine is the biggest drawback is that the fine sand (particle diameter is between 0.045mm and 1.6mm) will be in a serious loss and sometimes the loss will be over 20%. This drawback will not only reduce the output but also affect sand gradation. For this reason the gradation is not reasonable and fineness modulus is larger so that the product quality of mechanism sand will be largely reduced;
Fine sand recovery system process program is used for solving the problems mentioned above. KL series of fine sand recycling system also called mud purification equipment is widely used in sand aggregate processing system in hydropower station glass raw materials processing system artificial sand production line thick coal slime recovery in coal dressing plant and environmental protection engineering (mud treatment) etc
Features
1. Reduce the fine sand losing
2. the recycling rate of fine sand can reach 90%
3. Fines 0.10-3mm brings good profits
4. Stable vibration
long serving life and easy maintenance
Working principle
Through rubber pipes sand and water mixture is extracted from cleaning tank into slurry pump. The fine sand is collected by the centrifugal force of the cyclone then fed to the polyurethane screen from the apex spray. The 0.1-3mm fine sand and water are efficiently separated through the vibration screen. The waste water will flow back to the return box
through weld chute or pipes flowing to a settling pond.
