The drum screen is a horizontally inclined steel drum which spins round its axis
The material is fed into the inside of the drum through a chute. The rotation turns over the material, and the helical vanes guide the material along the screen, allowing material of the right size to fall through. Perforation can be changed so the output size can be varied.
With the drum screen several fractions can be separated at the same time if the perforation of the drum shield increases with the direction of transport. The structure is completely covered, has a direct drive, the wheels have high capacity so they provide calm and quiet operation and the whole structure doesn’t need too much maintenance.
