Pulp cleaner is a cleaning system used in the pulp and paper industry, it employs centrifugal forces to remove contaminants whose density differs from the pulp. Our pulp cleaner lineup consists of two types, namely high density cleaner, and medium & low density cleaner. These pulp cleaners are mainly composed of two parts, the upper part is made of stainless steel for long service life and the lower part is made of polyurethane or ceramic. In addition, upper cone liners are installed in the pulp cleaner.

High density cleaner sorts paper fibers out of heavy solid contaminants, like stapler pins, stones and glass, which will be thrown into a reject chamber. In contrast, the paper fibers inside the cyclone will move downward along the inside wall and stay at the center where centrifugal force is relatively small. Later the cleaned fibers will move to the center vortex and then ascend to the accept outlet. The pulp cleaner will efficiently eliminate contaminants since the centrifugal force will remain very strong as rotating radius becomes smaller, and the pulp will continue to rotate in high speed. The pulp cleaning machine is easy to clean since the cone of the cyclone is long and the head pipe is small. During operation, the loss of fibers will be reduced as the water pressure at the bottom is larger than that of pulp, so only larger contaminants, like sand, metal and fiber particles, and plastics will be rejected. The high density cleaner is equipped with a PLC cabinet, which brings hassle-free operating experiences to operators.

This medium and low density cleaner can sort paper fibers out of impurities suspended in consistencies ranging from 0.4-1.2%, such as concentrated light impurities, hot-melt impurities and heavy impurities. In addition to impurities, the pulp cleaner can also remove strips, plastics, particles and other substance, including wasted pulp, foamed plastics, ink particles and air. This pulp cleaning machine accommodates several small hydrocyclones in one unit and during operation, vortexes will be produced inside of the cyclone to efficiently keep paper fibers and keep out contaminants. Due to the special design, there will be no deposits of contaminants.
