Patent DE-19902148-C2 (DE)
Inventor: NIEMCZYK BERNHARD
IPC: B03B5/28
Filed: 1999-01-20
Granted: 2001-03-29
Abstract: The invention relates to a device and a method for chemically and physically separating solid materials from a suspension using flotation. A rotationally symmetrical flocculation/flow reactor is provided with outlets in the lower part thereof and is arranged in a separating tank. At least one suspension inlet extends eccentrically into said reactor. The supplied suspension is guided into said reactor. The supplied suspension is guided into the upper area of the flocculation reactor via the suspension inlet. A circular flow is thus created which drains off from the flocculation reactor downwards in a tangential and radial manner over the outer circumference into circularly arranged distribution cells which reinforce the tangential component of the suspension flow when said flow is delivered into the separating tank. In prior art, the flow of the mixture consisting of the suspension and air-sacs extends radially outwards. One advantage of the invention is that said flow of the mixture has to travel a longer way to the outlets in the area of the wall of the tank due to the tangential flow component. The solid matter can be separated more effectively by virtue of the longer travel path or the longer presence in the separating tank.

Working surfaces of baffle plates of auxiliary working tool are oriented perpendicular to tangent to working tool circle. Surface layer of material is shifted downward in rolling mode by gravitational force resultant and by centrifugal forces along adjacent guiding surface with angle of inclination to vertical plane being less than 45 deg. Method is useful for disintegration of rocks and ores. EFFECT: increased efficiency and improved quality of ground material. 4 dwg
