Zero-Discharge Sand Washing Water Treatment System

Structure

Composed of motor, cyclone, ZKR linear vibrating screen, cleaning tank, return bin, etc.

Working Process

The pump transports the sand water mixture to the cyclone, and the fine sand that is centrifugally graded and concentrated is provided to the vibrating screen through the sand settling nozzle. After dehydration by the vibrating screen, the fine sand and water are effectively separated. A small amount of fine sand, mud, etc. are returned to the cleaning tank through the return bin. When the liquid level in the cleaning tank is too high, they are discharged through the discharge port. The weight concentration of materials recovered by the linear vibrating screen is 70% -85%. Adjusting the fineness modulus can be achieved by changing the pump speed, changing the mortar, adjusting the overflow water volume, and replacing the sand nozzle. Thus completing three functions: cleaning, dehydration, and grading.

The fine sand extraction device is widely used in various processing systems designed based on actual sand powder conditions:

• Sand and gravel bones of hydropower stations
• Material processing systems and glass raw material processing
• Manual sand production lines
• Recovery and Environmental Protection Engineering of Coarse Coal Slime
• Coal Preparation Plants (Mud) purification and fine sand recovery
