How to Configure the Dewatering Screen

The dewatering screen is vital equipment in the sand washing process. The correct configuration of the dewatering screen to classify the materials can not only avoid dust pollution, but also improve production efficiency. But how to size the dewatering screen to achieve the best effect? This article introduces several aspects for your reference.


1. Whether the Dewatering Screen is Used in Combination or Alone has High Efficiency?

Sand washing machine is a necessary product for sand washing, but for fine-grained materials, if only the sand washing machine is used, it cannot clean it. Therefore, in the sand washing stage, a dewatering screen device is equipped. Sand and gravel are cleaned by a sand washing machine and then subjected to secondary water washing, hydraulic classification, and desliming through a vibrating dewatering screen to achieve a reasonable particle size ratio and reduce the mud content to less than 0.7%.
When the mud content of the material is small, the dewatering screen can be used alone with no sand washing machine. Because if the sand washer is employed to cleaning, the material will be washed away with the mud, which will damage the output of sand.


2. Different Materials Affect the Selection of Dehydration Screen

Some people believe that a dehydration screen can operate all materials. However, this will only reduce the service life of the water screen and reduce the quality of finished sand. In the operation, we should select the dehydration screen according to the particle size of the material to meet the dehydration requirements of various materials.

3. Specification Configuration of Dewatering Screen

Different model configurations have changed processing capacity, dewatering capacity, and screen size of the dewatering screen, so the scope of use is also different. Generally, the length of the screen of the dewatering screen affects the size of the dewatering capacity, and the width affects the size of the disposable product processing capacity. You can choose the appropriate dewatering screen according to the total amount of materials to be processed and the moisture content of the finished sand. A suitable dewatering screen can not only ensure work efficiency and product quality, but also guarantee the service life of the machine.
