Description
Technical field
The utility model relates to paper making equipment technical field, particularly relates to a kind of multisection type mill pulping system.
Background technology
Making beating is the requisite procedure of papermaking, and the quality of refining pulp quality, directly has influence on the intensity of paper products and the adhesion of fiber.Making beating has wire-dividing broom purification (fibrillating) to fiber and the effect such as to prescind, and is not oversize fiber, avoids prescinding as far as possible for length; Fully moisten for passing through the fiber risen, the probability of cut-out can greatly reduce.
At present, beating equipment has clearance-type beater and continous mode beater, and clearance-type beater is due to quality instability, and production capacity is low, and seldom adopt in Modern Paper Machine at a high speed, what continous mode beater was the most frequently used is mill beater.
Traditional mill beater comprises two or more toothed mills, and paper pulp passes through from two mills, on the whole fiber added wherein of the pressure of mill, is pulled an oar by the pressure improving two mills.But this structure mill can make a large amount of fibers be prescinded, cause beating results poor and unstable, thus cause finished product paper of poor quality, and energy consumption is high, production cost is high.
