Title:
APPARATUS FOR TREATING SUSPENSION
Document Type and Number:
Japanese Patent JP3527612
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To effectively grind a suspension in both of positive and negative pressure operations by providing the apparatus with a propeller stirrer, an anchor-shaped stirrer or a turbine stirrer as a stirring mechanism and/or a feed mechanism.
SOLUTION: A feed mechanism is formed as the propeller stirrer 26 positioned under a lower end surface 21 and a propeller stirrer 27 positioned above an upper end surface 20. A suspension is subjected to the effect of the feed action of the propeller stirrers 26, 27 to flow in an insertion member 11 through the lower end surface 12 to flow through a grinding floor and, at this time, the suspension is subjected to the grinding action of grinding balls 25 always mutually tumbled on the basis of rotary motion. At this time, since the propeller stirrer 26 is fitted just above a bottom part 2, turblent flow and negative pressure are generated to prevent the sedimentation of a solid within the bottom range of a reaction container 1. By this constitution, the suspension can be effectively ground in both of positive and negative pressure operations.
