Dewatering Screens | Mellott
Dewatering screens are mainly used to remove liquid particles from aggregate mixtures that may include a combination of sand, coal, iron, ore, and more. The screens separate liquids from solids using a mesh or wire cloth. This is an essential step in many processes, such as water treatment, aggregate mixture preparation, and wastewater management.
Dewatering Screens
Our dewatering screens can produce a finished fine material product with a moisture content as low as 8 percent. These single-deck screens dewater fine aggregates prior to stockpiling. By utilizing a dewatering screen, producers can cut drying time significantly and get material out the door quickly.
SCREEN CAPACITY CALCULATION
depend greatly on the design of the screen, and most capacity formulas assume the screen design is correct for the application. This assumption is not always justified. A scalping screen used as a finishing or dewatering screen would have a greatly reduced capacity. A finishing screen used as a heavy scalper would also have a greatly reduced ...
