The dewatering screen is one of the indispensable pieces of equipment for the sand and gravel production line. The answers to common questions about dewatering screens in production are as follows.
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 dewatering screen, Coal slime dewatering screen, tailings dewatering screen, high-frequency dewatering screen, etc.
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 for washing materials in industries such as sand quarry, mining, building materials, chemical industry, and concrete mixing plant. Selection, classification, and dehydration.
Although both belong to the dewatering equipment, the structure of the dewatering screen is different when it acts on different materials. For example, the sand dewatering screen on the sand washing production line and the tailings dewatering screen commonly used in the concentrator is different equipment. The former mainly uses It is used in the wet sand production line and used with sand washing machine, or it can be used alone.
The sand washed by the sand washing machine is not very clean. The sand has a large mud content and is too wet (high water content), which does not meet the production requirements of the sand mud content standard, so a dewatering screen is required. The sand and gravel are cleaned by a sand washing machine and then passed through a dewatering screen for secondary water washing, hydraulic classification, desliming, and dewatering to achieve a reasonable particle size ratio and reduce the mud content to less than 0.7%.
The dewatering screen can also be used alone when it is used for some materials with low mud content. No sand washing machine is needed, such as quartz sand. Because quartz sand generally contains low mud content, using a sand washing machine to wash sand not only consumes energy but also has a poor effect. It is important that the investment cost of the dewatering screen is lower than that of the sand washing machine.
There are not many vulnerable parts of the dewatering screen, usually screens, screen plates, vibration motors. The frequency of replacement needs to be determined according to the actual situation of the user, which may vary greatly.
