Vibratory Screens come in a variety of sizes. They can range from 4' to 12' wide and 6' to 32' long. The width of the screen determines the carrying capacity of the screen deck, while the length of the screen determines the overall efficiency of the screen. Typically, the length of the screen is 2.5 to 3 times the size of the width.
The trommel screen consists of a cylindrical metallic surface, which rotates a complete 360° around a longitudinal axis. The cylindrical screen has several apertures through which smaller waste elements pass through the mesh, creating two or more waste streams differentiated by size. ... When the trommel rotation speed is low, ...
Step 4: Attach the Hardware Cloth to the Rims. Place the hardware cloth inside the rims and attach with wires through the spoke holes. I used plastic coated #14 electrical wire. To fasten the seam of the tube I used #18 wire. (Be careful not to over tighten the wire or the wire will break.) Make sure the wire on the outside of the rim ...
Rotating trommel screens with water sprays are also used to process and wash wet sand and gravel. Screening separates the sand and gravel into different size ranges. Water is sprayed onto the material throughout the screening process. After screening, the sized gravel is transported to stockpiles,
