High Speed Pulper Washer

The high-speed pulp washing machine feeds the pulp into the gap between the polyester mesh and the breast roller through the headbox. The breast roller drives the mesh and the couch roller to operate at high speed. The pulp at the breast roller is subjected to the combined action of the extrusion pressure of the mesh and the breast roller and the centrifugal force generated by the high-speed operation, enabling the pulp to be dehydrated and washed. When the pulp reaches the roller along the mesh, it is further dehydrated by the extrusion and centrifugal force of the mesh and the couch roller, Then, the slurry is scraped from the couch roller into the discharge screw by a scraper. In the above process, due to the thin pulp layer between the mesh and the roller, the ink particles, fillers, and other fine impurities in the pulp are rarely hindered by the pulp layer during the removal process, and are easily removed with water.

Deinking Machine

Purpose and characteristics of closed flotation deinking machine: The fully closed multistage flotation equipment uses a special structure of interstage separation device to form a hierarchical multistage flotation, preventing the mixing of pulp between different flotation stages. The dispersion of air and the mixing of pulp are accomplished by a specially developed non clogging jet system. This unique device structure allows the pulp to undergo internal circulation, and the air is used multiple times in the pulp, Greatly improve the utilization rate of air and the deinking rate of pulp. This equipment has significant advantages such as high deinking efficiency, high whiteness of the deinked pulp, good brightness, high ink removal concentration (up to standard 3% or more), minimal fiber loss, small floor area, simple operation and control, and low energy consumption. This equipment is suitable for flotation deinking of various types of waste paper at home and abroad. While removing ink, some lightweight adhesives and lightweight plastics can also be significantly removed.

Digestor

Used for pulping line with materials of wood, straw, bamboo, bagasse and so on.

Disc Filter

As the latest generation of white water recovery and pulp thickening equipment, this product can save energy,reduce water consumption and fiber loss,while protect the environment and prevent pollution. It is mainly suitable for white water recovery in paper mills, and its performance is superior and meets advanced national standards.

In the white water recovery process, the fiber recovery rate is high, water circulation is achieved, water consumption is reduced, and white water pollution is prevented.

The fan-shaped plate has excellent structure with high strength, easy disassembly, large effective filtration area and good filtration effect.

The equipment products have complete specifications and various diameters, and filtration area can be changed according to different production requirements.

The adjustable distribution valve made of special wear-resistant material has good sealing effect. The composite sealing tape can provide the maximum sealing effect.

Compact structure, small area occupied and high yield. 

Good economic and social benefits
