The Main Features of Coarse Screen

Coarse screen is in addition to the minimum aperture grille outside mesh sieve size larger than 25mm or strip sieve. coarse screen is an advanced pulp screening equipment. With a screening of high quality, large capacity, high screening efficiency, wear a small, low energy consumption, fiber loss characteristics. Especially suitable as a variety of waste paper fiber material coarse screening devices to block or remove water or waste water flowing state of suspended or floating solids.
Coarse screen’s operation, the slurry from the bottom into the casing along the tangent, the centrifugal force, the weight of slag slag weight along the housing is moved into collection ports, light impurities rise to the rotating light slag discharge port. Therefore, in addition to both coarse sieve and light impurities, heavy impurities and other functions. With a large output, low energy consumption, safe, drum sieve long life, low operating costs, simplify the process design characteristics.
The main features of coarse screen can be summarized as follows:
1. High screening efficiency, able to handle a large quantity of slurry containing slag;
2. Good pulp flow, heavy slag removal efficiency, long life drum sieve;
3. Rotating drum sieve low energy consumption, intermittent slag, fiber loss small.
