Energy Saving Technology using MF Screen for the Screening System in the Kraft Pulping and Secondary Fiber Processes

Result and Improvement on the MF Screen Application

Abstract

In the conventional secondary fiber system and Kraft pulp system, the reject rate must be larger to keep the higher screening efficiency, and the shives, fiber bundles in the reject stock must be also deflaked to maintain the higheryield.
In consequence, the screen system, particularly thereject line, will go to larger and more complicated scale, and it will lose much energy.
The MF Screen, developed by Ishikawajima Industrial Machinery Co., is the revolutionary device which can enormously reduce the energy consumption and extensively simplifies the conventional screen system, while keeping the screening efficiency of the accept stock. The MF Screen can reduce both energy and initial cost by about 50 percent compared with the conventional screen system.
