Beater

Name:
Beater
Detailed information:
An open, oval tank into which digested paper pulp is fed together with water and other processing ingredients such as clay, rosin, pigments, etc. The resulting slurry (approximately 5% solids content) is strongly agitated by a rotating drum equipped with closely spaced, horizontal, finlike projections which effectively disintegrate and macerate the wood fibers while the slurry is continuously circulated. The time of beating varies with the type and quality of the paper being made. Conical refiners (called Jordans) are often used to complete the beating operation for high-grade papers. The beating operation is critical in converting wood pulp to paper.
