Gravity disc thickener is a type of paper pulping equipment. It is mainly used for the thickening of low concentration pulp. For the mechanical wood pulp, waste pulp, reed straw pulp, bamboo pulp, bagasse pulp with a low free degree or short fibers, gravity disc thickener can be selected to increase the concentration. This machine is different from the traditional vacuum disc filter. It does not need to be installed in a high place, nor does it need to install a special water leg pipe to achieve vacuum.
Advantages of gravity disc thickener
- Applicable to mechanical wood pulp, waste pulp, reed pulp, bamboo pulp, bagasse pulp, wheat straw pulp with lower freeness (higher beating degree), shorter fiber, or higher consistency;
- Easy operation, reliable running, high production capacity, less power consumption, and convenient management;
- Segments either perforated with stainless steel cloth or grated with a polyester cloth.
