The pulp flat screen type (Somerville-type screening) is used to sift the impurities in the slurry and determine the content of impurities such as debris in the pulp. It is used in the pulp and paper laboratory. The screening machine can reduce the amount of impurities in the pulp suspension that do not meet the process requirements, and obtain a clean good pulp. The machine is a flat-plate vibrating screen machine with a size of 270×320. It can be equipped with sieve plates with different specifications. It is a kind of pulp that will be used to screen pulp fibers by vibrating vacuum suction. At the same time, the machine can also be used as a flat screen.
The purpose of sieving is to separate impurities such as debris from the mechanical pulp, and large viscous materials, plastics, sediment, iron filings and flakes in the pulp regenerated fibers, which are then inspected and quantified.
The flat screen sieving machine adopts a speed reducer to drive the cam through the connecting shaft, vibrating the bottom plate up and down, so that the slurry generates high frequency vibration, the qualified slurry passes through the sieve joint, and the unqualified fiber and slag remain on the sieve plate.
