CNBM’s Single Screw Press
- apply for making straw pulp, wood, etc.
- prevent smell, black liquior overflow.
- high dewatering rate, high pulp drying.
- high pulp concentration, low power consumption
- low rotary speed, no noise.
Single screw press is the squeeze pulp equipment that is used for paper pulp dehydration. In general, single screw press is mostly designed for black liquor of wood pulp, bamboo pulp, wheat straw pulp after cooking and high effective concentration of waste paper pulp. Single screw press is mainly applied for black liquor extraction in the large-scale pulp mill. It is installed in the spray storage and squeezes the black liquor from the pulp depend on the variational diameter-pitch screw, finally black liquor from the filter box to the black liquor tank.
In principle, after being cooked, the pulp is injected into single screw press. Then, the water and black liquor are separated from the pulp by squeezing, so as to achieve the purpose of black liquor extraction. Meantime, due to the squeezing of pulp actually produces the result of impressafining.
Composition of single screw press
Single screw press has many parts including feeding bearing, screw shaft, main bearing, filter drum, intermediate support, reel, feed port, foot section, a discharge port, rack, hood, air cylinder, loading plug, transmission and etc.
The main part of single screw press as below:
Single screw press from CNBM can effectively handle pulp with a variety of feeding concentration. Concentrated paper pulp has uniform dryness and stable pulp production rate. The pulp passed the single screw press, fibers are rarely affected, no clogging, no skid design to reduce the wear and corrosion of the screw. The device can also be used to concentrate the finished pulp and sell it directly as a commercial pulp.
