1. What is a dewatering screen? What types of dewatering screens are there?
The main functions of the dewatering screen are dehydration, desliming, and deintermediation. It can be used for sand washing in sand and gravel plants, recovery of coal slime in coal preparation plants, dry discharge of tailings in mineral processing plants, etc. Mud dewatering screen, tailings dewatering screen, high frequency dewatering screen, etc.
2. What are the commonly used sand washing equipment?
Generally speaking, there are three types of sand washing equipment commonly used: spiral sand washing machine, impeller sand washing machine, and vibrating dewatering screen. The three are mainly used for washing, grading and dehydration of materials in sand and gravel fields, mines, building materials, chemicals, concrete mixing plants and other industries.
3. They are all dewatering screens. Is the sand and gravel dewatering screen the same as the tailings dewatering screen?
Although they belong to the same dewatering equipment, the structure of the dewatering screen is different when it acts on different materials. For example, the sand dewatering screen on the washed sand production line and the tailings dewatering screen commonly used in the concentrator are different equipment. The former is mainly used In the wet sand production line, it is used together with the sand washing machine, or it can be used alone.
4. Why should a dewatering screen be configured with a sand washing machine?
The sand has a large amount of mud and is too wet (large water content), which does not meet the production requirements of sand and mud content standards, so a dewatering screen is required. The sand is cleaned by a sand washing machine, and then washed by a dewatering screen for a second time, hydraulically classified, deslimed, and dehydrated to achieve a reasonable particle size ratio and reduce the mud content to less than 0.7%.
5. Can the dewatering screen be used alone?
The dewatering screen can also be used alone when it acts on some materials with low mud content. It does not need a sand washing machine, such as quartz sand, because quartz sand generally has low mud content. Using a sand washing machine to wash the sand will not only consume energy but also have little effect. The most important thing is that the investment cost of the dewatering screen is lower than that of the sand washing machine.
6. What are the wearing parts of the dehydration screen, and are they replaced frequently?
There are not many wearing parts of the dehydration screen, which are generally screen mesh, screen plate, vibration motor and so on. The replacement frequency needs to be determined according to the actual situation of the user, which may vary greatly.
