Introduction

This type of Drum type hydrapulper is mainly used in the paper making industry to breaking continuously and coarse screening of the waste paper material under the high consistency.It can maximum keep the physical property of the fiber.

Advantages

1.Energy conservation.

Waste paper is broken under the condition of15-20% high consistency, reduce a lot water for breaking, reduce energy consumption for breaking, continuous breaking and slag discharge reduces the energy consumption of the auxiliary and subsequent equipment .

2.Improve the quality of the accepts.

Mild breaking without destroying the fiber strength and length, maximum limited guarantee the light impurities and parts of heavy impurities not broken,So ensure the cleanliness and quality of the accept.

3.Low equipment maintenance cost,save labor.

Drum pulper integrates high consistency breaking and coarse screening, simple structure, durable, is extremely low, and reduced labor for the waste paper selecting , so can save the expenses.

Operating Principle

1.Drum pulper set pulping and coarse screening with a body, used for continuous pulping all kinds of waste paper( newspaper, industrial board paper, mixed waste paper, etc.), and coarse screening the paper pulp after pulping, reject treatment equipment.

2.Drum pulper interior division presoak area, high consistency pulping area and screen area three industrial areas.

3.Waste paper raw material will from the conveyor into presoak area first, after soaking ,the waste paper then into the high consistency pulping area, under the consistency of 14% to 20%, with the rotation of the drum, the waste paper is took up by the lifting board on the inner wall , fall after rise to a certain height, and impact with the hard inner surface , so the waste paper in pulping area after repeated falls and strikes, under the mild pulping action of shear force and friction, was dissociated into single fiber, and the thin film,plastic, cloth and other impurities in the waste paper are not broken.

4.Waste paper pulp after breaking will go along the dip Angle under the drum drive, from pulping area into the screening area; on the above of screening area equipped with a flush water pipe , the pulp will washed and diluted once entered the screening area,The pulp consistency will down to 3-4%,Now,the acceptable fiber through screen holes into the pulp chest, rough impurity is blocked by screen plate , stay in screening area and constantly elutriated, finally discharge from discharge mouth at the end of drum .
