Dehydration of stone cutting fluid

During the slicing process of marble blocks, water is added to lubricate the cutter, and the resulting stone chips, stone powder and lubricating water are mixed into a slurry.

Stone cutting liquid solid-liquid separation

Before use: The stone cutting fluid flows into the sedimentation tank for sedimentation. When the sedimentation tank is full, a tanker is hired to clean the tank 2 to 4 times a month. The single cost is about 3,000 yuan, and the annual cleaning cost is about 100,000 yuan; current national environmental protection requirements It is becoming more and more strict, and the slurry water is secretly discharged after the tanker clears the pond, which is not a long-term solution.

After use: After using the dry sieve, the stone powder can be dried to make bricks and can be reused as cement additives.

Stone cutting liquid-solid-liquid separation system technology

The slurry with a concentration of 5% flows from the cutting workshop into the sedimentation tank. The backflush submersible pump pumps out the slurry with a concentration of 15~30% and pumps it into the cyclone to concentrate it to more than 50%. The underflow enters the dry discharge screen for dehydration and dry discharge, and overflows into the clean water tank. It is recycled in the cutting workshop; due to non-continuous operation, the fixed selection is: the flow rate of the submersible pump is 80m³/h, a cyclone is ¢300, and a dry discharge screen VDQ-1030 is used. According to the amount of sediment settled in the sedimentation tank every day, Open the dry drainage system for 3 to 5 hours to complete circulation of the sedimentation tank slurry.

    Dewatering Screen

    Dewatering screen adopt dual-electrode self-synchronization technology, universal eccentric block, adjustable amplitude vibrator. The machine is combined mainly by the screen box, exciter, support system and motor. The two mutually independent vibrators are respectively driven by the tape coupling to do synchronous reverse operation. The centrifugal force generated by two eccentric masses is superposed along the vibration direction and reversely counteracted, thereby forming a single vibration force along the vibration direction, making the screen box reciprocating linear motion.

    Dewatering screen, also known as high-frequency dewatering screen, changing the water surface tension of pulp through the exciting force, pulp water through the screen to become the undersize material, and fine material is blocked by the screen to form the filter layer by the vibration of the forward movement of discharge. Dewatering screen is mainly used for detailings dewatering in the mineral processing industry, coal slurry dehydration of coal preparation plant, washed quartz sand dewatering and ceramic slurry dehydration, and wet and dry classification, dehydration, removal and mud removal of medium and fine granular materials in industrial sectors such as electric power, sugar making and salt making.
