Used with hydrapulper system to screen out coarse impurities and improve the purifying efficiency of process.

Application:

ZST series drum screen is usually equipped with pulper or impurity separator, it can screen out all kinds of light or heavy impurities whose geometric shape are greater than 10mm such as plastics, rubber, sand, stone,metal pieces,film,etc.

Design Features:ZST series drum screen consists of screening drum, belt driving device, catch wheel, drawing wheel, vat, inlet trough, spray pipe, etc. While the screening drum rotates, pulp is conveying forward to the drum cylinder. 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.
