Usage: Pulp enters into screen in tangent direction under relatively high pressure, so the fiber and coarse foreign particles have already been separated before pulp enters screen drum by the centrifugal force. The qualified fiber will pass through screen drum with the help of differential pressure at pulping inlet and outlet. At the same time, high-rotating rib plates play the role of cleaning surface gaps on screen drum. Comparing with other types of screening equipments, under the condition of same driving force and screening area, this screen has better screening efficiency and pulping quality.
