Design Features:
ZST series drum screen consists of screening drum, belt driving device, catch wheel, drawing wheel, vat, inlet trough, spray pipe, etc. As the screening drum rotates, pulp is conveying forward by screw flight in drum. By gravity, accepts and fine impurities passing though 8~14mm
screening slots enter the vat. The larger impurities retained on screen plate is pushed forward to the end by screw flight. The fiber adhered to the impurities is washed off by fan nozzles in order to prevent fiber loss with impurities discharging.Simple structure, safe and reliable in operation and high efficiency in coarse screening.Used with hydrapulper system to screen out coarse impurities and improve the purifying efficiency of process.
