Paper Repulper

Paper Repulper

Today the development trend of waste paper pulping is to remove pollutants in the pulping stage as much as possible to save power consumption and reduce the burden of removing pollutants in subsequent processes; light and heavy impurities are removed as much as possible, reducing the burden of subsequent processes. Paper repulper is an important equipment used for it.

paper repulping machine

ZDG Series Drum Hydraulic Repulper

The paper repulper is the equipment that integrates pulping and screening, and is especially suitable for the pulping of unsorted waste paper. It will have greater economic and social benefits for expanding the recycling and utilization of secondary fibers, reducing environmental pollution, saving energy, realizing localization of paper making equipments. The drum repulper is used to carry out the high concentration (14%-22%) of waste paper, continuous disintegration and coarse screening.

Main Features

  1. Perfect fiber disintegration
  2. Excellent pulp quality
  3. Great energy saving effects
  4. Good deinking mechanism
  5. Reliable continuous deslagging system
  6. Reducing equipment costs
  7. Saving labor
  8. Minimum maintenance costs


The paper repulper has a roll-shaped rotary drum, simple structure and novel design. It consists of feeding hopper, rotary drum, transmission device, roll device, retaining wheel device, sealing device, protective cover and pulp chest.

D Series Hydraulic Repulper

The paper repulper is mainly used to disintegrate various pulp boards, broken papers and various waste papers.


D series hydraulic repulper is mainly composed of D-shaped tank body, rotor device and pulp disc, bracket, motor and protective cover.

  1. D-shaped tank body

It is welded by steel plates, the outer part of the upper part is reinforced with channel steel, and guide plate is placed inside conical bottom to make the pulp flow back to form a circulation. At the bottom of the tank there is a rectangular interface connected to the sediment well, which is opened on site by the user according to the process requirements.

  1. Rotor device

It includes rotor, screen plate, pulp discharge disc and transmission device.

  1. Bracket

It is welded from steel plates to support the tank and rotor device.

Medium-concentration Paper Repulper

Medium-concentration repulper is mainly used to disintegrate various pulp boards, broken papers and various waste papers. It has the characteristics of strong dissolving ability, wide adaptability, simple structure, convenient operation and maintenance, etc. It is the best equipment for waste paper pulping. This series of hydraulic repulpers are suitable for both batch production and continuous production.


ZDS series medium-concentration repulper is mainly composed of tank body, rotor device, transmission device, pulp level box (continuous type) and so on.

High-concentration Repulper

ZDSH series high-concentration repulper is designed with reference to foreign technical materials. It is mainly used in the waste paper deinking process. It can disintegrate waste paper at high concentration and water temperature of 60-90°C quickly, and at the same time, through chemical actions, it separates ink particles, fibers, ink particles and impurities are kept as large as possible, so that the subsequent ink removal, screening, purification and other processes can be carried out smoothly, using waste paper to produce a high whiteness pulp and saving steam, medicine and power consumption. High-concentration hydraulic repulper has become one ofthe core equipments in the waste paper deinking pulping process.


ZDSH series high-concentration repulper has a vertical structure, and is mainly composed of tank body, rotor device, transmission device, pulp discharge disc, bracket and so on.

Pulp is a lignocellulosic fibrous material prepared by chemically or mechanically separating cellulose fibres from wood, fiber crops, waste paper, or rags. Many kinds of paper are made from wood with nothing else mixed into them. This includes newspapers, magazines and even toilet paper. Pulp is one of the most abundant raw materials.

A pulp mill is a manufacturing facility that converts wood chips or other plant fibre source into a thick fibre board which can be shipped to a paper mill for further processing. Pulp can be manufactured using mechanical, semi-chemical or fully chemical methods (kraft and sulfite processes). The finished product may be either bleached or non-bleached, depending on the customer requirements.

A paper machine (or paper-making machine) is an industrial machine which is used in the pulp and paper industry to create paper in large quantities at high speed. Modern paper-making machines are based on the principles of the Fourdrinier Machine, which uses a moving woven mesh to create a continuous paper web by filtering out the fibres held in a paper stock and producing a continuously moving wet mat of fibre. This is dried in the machine to produce a strong paper web.

The pulp produced up to this point in the process can be bleached to produce a white paper product. The chemicals used to bleach pulp have been a source of environmental concern, and recently the pulp industry has been using alternatives to chlorine, such as chlorine dioxide, oxygen, ozone and hydrogen peroxide.

Chemical pulp is produced by combining wood chips and chemicals in large vessels called digesters. There, heat and chemicals break down lignin, which binds cellulose fibres together, without seriously degrading the cellulose fibres. Chemical pulp is used for materials that need to be stronger or combined with mechanical pulps to give a product different characteristics. The kraft process is the dominant chemical pulping method, with the sulfite process second. Historically soda pulping was the first successful chemical pulping method.
