Disc filter, also known as disk filter, vacuum disc filter, is usually used in washing bleaching system of chemical pulping or chemi-mechanical pulp. From the structure, vacuum disc filter is composed of spindle, tank, distribution valve, disc filter sector, and screw discharger, etc. For the functions, vacuum disc filter is the equipment that takes vacuum negative pressure as driving force for solid-liquid separation, which is widely applied in white water recycle and paper pulp thickening.
CNBM manufacture the vacuum disc filter, which is the last generation of white water recovery equipment. As the important equipment for white recovery and pulp thickening in paper making process, disk filter has advantages of energy efficiency (water consumption and fiber loss content) and environment protection. With the great performance, our vacuum disc filter has successfully reached the national advanced standards.
