Working Principle
NLS inflow pressure screen is a continuing screening equipment under a fully closed position with pressure.
When works, the pulp enters into the outside of the screen drum in a the tangent direction through the pulp pipe. Qualified pulp enters into the screen drum through the sieve seam (hole), with the help of pressure difference between the inside and outside of the screen drum, then comes out through the pulp pipe. The pulp and impurities which cannot through the sieve seam (hole) fall down to the bottom, and come out from the discharge pipe.
Rotating the blade outside the screen drum can produce a moderate pressure, which improves the circulation flow of pulp, its tail will produce a negative pressure, which has the effect of backwash sieve seam (hole). It can prevent the sieve seam (hole) congestion, and pulp can smooth enter through the sieve screening (hole) from the surface constantly, which ensures the continuous operation.
