Title:
METHOD AND APPARATUS FOR BEATING FIBROUS MATERIAL
Document Type and Number:
Japanese Patent JPS52110907
Kind Code:
A
Abstract:
Method and apparatus for coordinating the rate of feed and the moisture content of the pulp material to the heat quotients of the mechanical energy input in a refiner system in which the moisture-containing pulp material is introduced at an adjustable rate of feed into the central portion of an axially adjustable grinding space defined between a pair of grinding discs which rotate relative to one another within a closed housing and in which grinding space the material is propelled by centrifugal force created by the rotation of the discs in an annular radial path toward the periphery of the discs while being subjected to a grinding operation in an environment of steam generated by the heat produced by friction in the grinding space. The heat quotients of the mechanical energy are sensed as the pulp material progresses along its radial annular path in the grinding space and the rate of feed and moisture content of the material and the width of the grinding space are coordinated to the sensed heat quotients to produce pulp of optimum values with minimized consumption of mechanical energy.
