High Concentration Disc Refiner

The high consistency disc refiner is the most basic instrument used in the experimental and research fields of the pulp and paper industry. It can make wood chips into pulp, improve the pulp, or make wood chips into synthetic fibers, glass fibers, and carbon fibers. In many fields, using a high consistency disc refiner can easily convert wood chips into fibers and various types of fine fibers. This machine is not only an ideal experimental equipment for the pulp and paper industry, it is also widely used as grinding experimental equipment or production equipment in industries such as metallurgy, building materials, plastics, and food.
