一、Brief introduction of high concentration shredded paper pulping machine：

High-concentration shredded paper pulping machine is a high consistency kneading and breaking equipment for deinking pulp of waste paper. Suitable for waste paper such as book paper, electrostatic copy paper, report magazine paper, newspaper, etc. (pulp crushing concentration is 10-16%). Waste paper is softened by mechanical force, soaking in hot water and osmotic softening of surfactant, and by the combined action of deinking agent and stripping agent，Dispersion, ink separation, stripping the printed ink from the paper surface and fiber.

二、Characteristics of high concentration shredded paper pulping machine：

1、High-concentration pulper has the characteristics of high pulp breaking concentration, and the pulp breaking concentration is between 12% and 18%. It can greatly reduce the energy consumption of pulp heating and the consumption of chemicals when used for deinked pulp of waste paper. The friction between paper and fiber is large, and the stripping and loosening effect by screw auger is good, which promotes the ink particles to be stripped and dispersed from the fiber more quickly. But also has almost no cutting effect on a single fiber; Small damage to impurities and the like.

 2、The discharging dilution device can directly discharge the high-consistency slurry without dilution in the barrel of the pulper, which greatly shortens the discharging time of the high-consistency slurry, reduces the power of the equipment, saves power consumption, and can control the concentration of the slurry evenly and accurately.

The characteristics of this series of devices include:

1. It can dewater waste paper at high concentrations of 10-16%, and flexibly dewater to protect the fiber strength of recycled pulp.

2. For mixed waste paper containing a large amount of impurities (such as plastic, metal sheets, gravel, etc.), it is not easy to break the impurities, which is beneficial for the screening and purification of subsequent processes.

3. The intermittent batch pulping method is easy to control in terms of temperature control, dosing, water volume, and pulping effect. Save electricity and heat, and reduce the amount of chemicals used.
