Rotary Drum Screen
Munson Machinery March 10, 2015
A new, compact Rotary Drum Screen from Munson Machinery removes solids from industrial and municipal waste streams, and recovers solid product from process streams, at rates from 600 to 2,790 gal/min (2,270 to 10,560 liter/min) without blinding or clogging the screen, while reducing floor space and headroom requirements compared with non-rotating equipment of equivalent capacity, according to the company. Solids-laden effluent discharges from the head box and overflows a weir, flooding the entire length of the variable speed, rotating wedgewire drum screen. Solids deposited on the screen gravity-drain through slotted apertures to moisture levels in the 20% range before being removed by a doctor blade and chute.
