   Scope of application:

1. Construction site. The graded sand can be used in the construction of coarse sand, which can be used to improve the modulus of coarse sand and make it easier to use the coarse sand in the construction.

2. Sand washing production line. Sand washing line can improve the quality of sand washing by using the sand washing line In order to reduce the pressure of environmental protection and environmental protection of enterprises, it is necessary to reduce the area of sedimentation tank and reduce the pressure of environmental protection.

 Principle of dewatering screen

   Structural composition:

The dehydration screen is divided into dehydration and recovery systems. The dehydration part includes dewatering screen and vibration motor, and the recovery part includes vacuum high-pressure pump, motor, high-pressure separator, return water tank, cleaning box, etc.

   Workflow:

The coarse sand from the sand washing machine directly enters the screen surface of the dewatering screen. Driven by the screen machine and vibration motor, and combined with the negative angle climbing structure designed by the screen machine, the material vibrates on the screen surface with high frequency to form a filter layer and dehydrate, thus realizing the function of coarse sand dewatering; The sand washing wastewater overflowed from the sand washing vibration dewatering screen enters the cleaning box of the equipment, and is pumped into the cyclone by the bottom vacuum high-pressure pump for grading concentration. Through the high-speed centrifugal force and the rated feed pressure, the cyclone separates the fine sand in the sand washing wastewater from the water, and then discharges the fine sand with the concentration of 60-70 into the surface of the vibration dewatering screen through the sand settling nozzle, and vibrates at high frequency Driven by the motor, the dewatering and recovery of fine sand is realized, and other impurities such as waste water, mud and powder are discharged into the return water tank through the overflow port of the cyclone.

 Dewatering screen

The dewatering screen has achieved remarkable results and has been recognized by most users. The above is about the introduction of dewatering screen.
