dewatering screen

1. What is a dewatering screen? What types of dewatering screens?

The dewatering screen is mainly used for dewatering, desliming and degrading. It can be used for sand washing in sand and gravel plants, coal slime recovery in coal preparation plants, and dry tailings of concentrators, so it is also called sand dewatering screen, mine dehydration screens, coal slime dewatering screens, tailings dewatering screens, high-frequency dewatering screens, etc.

2. What are the commonly used sand washing equipment?

Generally speaking, the commonly used sand washing equipment includes spiral sand washing machine, impeller sand washing machine, and vibrating dewatering screen. The three are mainly used in the industries of quarrying, mining, building materials, chemical industry, concrete mixing station, etc. carry out washing, classification and dehydration.

3. They are all dewatering screens. Is the sand dewatering screen the same as the tailings dewatering screen?

Although they are all dewatering equipment, the structure of the dewatering screen is different for different materials.
The sand-gravel dewatering screen is mainly used in the wet sand production line and used with the sand washing machine. The tailings dewatering screen is used in the beneficiation plant.

4. Why should a dewatering screen be equipped after a sand washing machine?

Because the sand washed by the sand washing machine is not very clean. The sand has high mud content and high water content, which cannot meet the sand mud content standard. If sand and gravel are cleaned by a sand washing machine first, and then passed through a dewatering screen for secondary washing, hydraulic classification, desliming, and dewatering, to achieve a reasonable particle size ratio, the mud content can be reduced to less than 0.7%.

5. Can the dewatering screen be used alone?

For some materials with low mud content, the dewatering screen can be used alone without sand washing machine. For example, quartz sand, quartz sand generally has a low mud content. Using a sand washing machine to wash quartz sand not only consumes energy but also has poor effect. The important thing is that the investment cost of a dewatering screen is lower than that of a sand washing machine.

6. What are the wearing parts of the dewatering screen and are they replaced frequently?

There are not many vulnerable parts of the dewatering screen, usually screens, screens, vibration motors, etc. The frequency of replacement depends on the actual situation of the user and may vary greatly.
