Coarse Material Washer
Gravity-Based Rock Sizing
With robust construction and advanced screening mechanisms, the Anthem Inclined Screen ensures superior material separation, reduced downtime, and increased productivity.
Anthem Screens are typically used in fine and coarse screening applications or for operators requiring a scalping stage, which removes oversized materials before the crushing or processing circuit.
Standard duty applications include a 2-bearing, single shaft design, while 4-bearing dual shafts are manufactured for the most demanding requirements.
Applications:
Ore/Hard Rock Mining
Quarried Stone
River Gravel
Recycled Concrete
Fractured Gravel
Cubicle Products
Super Pave Products
Advantages
01.
Skidded Frame
Adds rigidity to the machine so that its shape stays solidly square during installation and operation.
02.
Belly Pan
A curved design eliminates dead spots while a flush back nozzle enhances the material cleaning process.
03.
Overflow Gate
Adjustable feature allows control of water bed depth for a cleaner, drier product.
04.
Drive System
Utilizes an off-the-shelf, shaft-mounted gear reducer that is fully-guarded during manufacturing.
How Does A Coarse Material Washer Work?
Material is fed into the inlet of the tub as water is introduced through spray bars or nozzles. The water loosens and suspends unwanted materials.
As the material and water move along the length of the screw, shaft-mounted flights and paddles provide mechanical agitation. This action breaks up clumps, dislodges contaminants, and allows the water to thoroughly mix with the material.
Unwanted and finer materials form a slurry and are carried out the back end, while the cleaner and coarser material moves along the screw and discharges at the opposite end.
