What is Sand Dewatering Screens


Sand dewatering screen, the main function is dehydration, de-sludge, de-intermediation, can be used for sand washing in sand and gravel plant, coal slurry recovery in coal preparation plant, dry discharge of tailings in mineral processing plant, etc..

So it is also called sand and stone dewatering sieve, mining dewatering sieve, Slime dewatering screen, tailings dewatering screen, high frequency dewatering screen, etc. Although they belong to the dewatering equipment, the structure of the dewatering screen is different when it is applied to different materials.

For example, the sand and stone dewatering screen on the washing sand production line and the tailings dewatering screen commonly used in the ore dressing plant are different equipments. The vibrating dewatering screen is mainly used in a wet sand washing plant, and can be used together with a sand washing machine or can be used alone.

Used with sand washing machine

Why should the two be used together? We must know that the sand washed by the sand washer is not very clean. The sand not only has a certain amount of mud and is too wet (large water content), and does not meet the production requirements of low sand and mud content. Therefore, it is necessary to configure a vibration dewatering screen for dehydration and de-sludge treatment! After the sand and gravel are cleaned by the sand washing machine, and then de-sludged and dehydrated and sieved by the dewatering sieve, a reasonable particle size ratio can be achieved, and the mud content can be reduced to less than 0.7%.

Dewatering screen used alone

The dewatering screen can also be used alone when it is used in certain materials with low mud content. No sand washing machine, such as quartz sand, is required. Because quartz sand generally has low mud content, washing sand with sand washing machine not only consumes energy but also has poor effect. More importantly, the dewatering screen has lower investment cost than the sand washing machine.
