The working part is cylindrical, the entire screen around the axis of rotation axis in the cylinder, under the conditions of small angle into general. The material is fed from one end of the cylinder, and the fine material passes through the screen of the cylindrical work surface, and the coarse material is discharged from the other end of the cylinder. The speed of the cylinder screen is low, the work is steady and the power balance is good. But the sieve hole is easy to plug, the sieving efficiency is low, the work area is small, and the productivity is low. Concentrator seldom uses it as screening equipment.

Application:

YTS is usually device in pulp or magazine after centrifuges,It can screen out all kinds of light or heavy impurities whosee geometric shape are greater than 10mm such as plastics,rubber,sand,stone,metal pieces,film,etc.

Design  F eature:

YTS  is series drum screen consists of drum,belt driving device,catch wheel,drawing wheel,vat,inlet trough,spravy pipe,etc.While the screening drum rotates,pulp is conveying forword to the drum cylinder by screw flight.By gravity,accept and fine impurities passing though 8-14mm screening slots enter the vat.The fiber adhered to the impurities retained on screen plate is pushed forward to the end by screw flight.The fiber adhered to the impurities is wash off by fan nozzles in order to prevent fiber loss with impurities discharging.

Simple structure ,safe and reliable in operation and high effciency in coarse screening.

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