Abstract

An improved method for treating cellulosic material recovered from a disc refiner in a mechanical pulp making process. Latency removal is conducted at a medium consistency of from about 8 to 15 percent in a medium consistency pump after which the suspension is removed at a medium consistency first to a screening device and then to a storage tank. Cleaning then takes place at low consistency. The method affords efficiencies in the nature of reduced capital costs and energy consumption.
