Rotary Drum Screen for Waste Water Treatment

Rotary Drum Screen for Waste Water Treatment Rotary drum fine screen is mainly composed of cylindrical drum, driving device, supporting device, feeding device and discharging device. The drum is usually made of metal wire mesh or perforated plate, the surface has a uniform distribution of holes, the size of which determines the size of the screen. Working principle: the material to be processed from the feeding device into the drum drum, the driving device to drive the drum around its axis to do rotary motion. During the rotation of the drum screen, particles smaller than the size of the sieve holes will fall through the sieve holes to the collection device below, while particles larger than the size of the sieve holes will remain in the drum, and with the rotation of the drum gradually move to the outlet, and ultimately discharged from the outlet, so as to realize the separation of materials of different particle sizes. Rotating drum screen has the advantages of continuous opera…
