Zds Series Mc Pulper

Application:
Zds series m. C. Pulper is the key equipment in deinking process. At consistency 15~17% and under the effect of chemical and physical actions, waste papers such as newspaper, magazine paper filmcoated are disintegrated into fiber stock, and light impurities such as ink particles, plastics and films are separated from fiber efficiently.
Design features:
Zds series m. C. Pulper consists of a steel vat, vertical helical rotor,
Drive mechanism, discharging device etc.

The rotor is a 3-thread helical rotor with varied pitch and varied diameter. When the rotor rotates, the stock at the consistency of 15~17% is drawn by the helical rotor and flung from the top to the bottom, from outside to inside, and then out of center. As a result, waste paper stock is fiberized under intensive internal friction and kneading effect on fiber stock, in addition to friction by rotor vanes with teeth. Meanwhile, ink particles are separated from fiber by chemical and physical actions.

Compared with a low consistency pulper, slushing waste paper stock at the consistency of 15~17% results in saving energy 20~30%. The impurities in waste paper stock are easily detached from fiber without being smashed into small pieces easily and thus help cleaning of downstream process. Compared with low consistency pulping, it can save heat and power by 50% as well as chemical by 20% respectively.
