horizontal drum hydrapulper

Directions of accepts outlet and rejects discharge are perpendicular and independent from each other. Thanks to the structure of rotor and screen plate, screen holes are prevented from plugging by sand and impurities, therefore the hydrapulper keeps running and discharging rejects continually without plugging.

Drum Pulper is mainly used in the continuous pulping and coarse screening of all kinds of OCC waste paper, continuous defibering and deinking of newspaper, book paper, magazine paper, mixed office waste paper, eliminating the light and heavy impurities, stencil and gooey.

1.It can save energy, for the power consumption of the drum pulper is as low as 14~18KWh per ton of pulp.
2.Soft pulping and screening will not destroy impurities and gooey. Quality of accepts is clean, while gooey content is low.
3.It is not powerful pulping, so there is little wear and tear, which brings little maintenance costs.
4.DIP waste paper deinking consistency is 18-20% higher, which can save chemicals about 15-20%.
5.The control is simple, while PLC automatic control can be used.
6.There are 3 types of drum pulper: A is suitable for OCC waste paper; B is suitable for AOCC waste paper; C is suitable for DIP waste paper deinking.

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.
