Application

ZDR series roller type disperser is a single roller type one, and is a widely used key machine for the dispersion of waste paper pulp. It is generally used to deal with hot melt and sticky impurities such as grease and paraffin wax, and special ink particles.

Structure feature

ZDR series roller type disperser consists of rotator, stator, body, feeding port, pulp-discharging port, drive, control system, and heating system, etc.

The pulp-feeding screw conveys the pulp at a consistency higher than 28% into the disperser. The pulp is heated to 90 by steam in the body; Meanwhile the pulp is intensively stirred, sheared and kneaded in between the rotator and stator. As a result, the impurities that are stick to fibers, such as hot-melting and sticky substances as well as ink, etc., are peeled off the fibers and dispersed into fine particles; meanwhile the impurity particles that mix in the pulp, such as plastics and rubber, etc., shrunk into grain particles, so they are easy to be removed in subsequent screening and pulp-washing sections.

·No spoil to the fiber itself.

·High efficiency in dispersing and removing the ink particles and wet strength pulp which is difficult to be removed in waste paper pulping.

·Under the conditions of consistencies ≥28 and temperatures 100,the dispersers stirring shearing, and kneading functions can disperse hot melt impurities effectively, such as grease and paraffin wax, etc.; And can also dissolve the impurities with high melting points making it easy to remove them.

·Stable and reliable in machine structure, easy and safe in maintenance and operation. Reliable systems, such as pneumatic controlled pulp-discharging and load control and so on, assure dispersers best working results.
