MC Pulper

MC Pulper Application ZDS series MC pulper is a key equipment in deinking process. At consistency 10 15% and under the effect of chemical and physical action, the waste papers such as newspaper, magazine paper film-coated is disintegrated into fiber stock, and efficiently separated light impurities like ink particles and plastic films from fiber. Design feature ZDS series MC 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 rotating, the stock at consistency 10 15% is drawn by the helical rotor and flung out of center and 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. In meantime, ink particles are separated from fiber by chemical and physical action. Slush waste paper stock at consistency of 10 15% and saving energy 20 30% compared to a low consistency pulper. The contaminants in waste paper stock are easily detached from fiber without being smashed into small piece and hence to give a good condition to down stream cleaning process. For processing wet-strength paper, low PH and high temperature is required. So comparing to low consistency pulping, it can save heat and electric energy and chemical by 50% respectively. It is compact in structure, easier, safe and reliable for operating.
