Vibrating Mill. The vibrating mill GSM is a vibrating mill with exchangeable grinding barrels used to crush brittle and fibrous material down to high degrees of fineness. The size reduction is achieved by impact and friction inside two vibrating grinding barrels which are filled with freely moving grinding balls.
A hammer mill is typically good for grinding softer materials with Mohs hard-ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materi-als become very abrasive; therefore, they are not suitable for high-speed hammer mills. In a typical jet mill, grinding
1 hr in a very efficient vibratory ball mill, such as the NBS-type mill first used by Björkman: to 12 hr in a large Siebtechnik vibratory mill, to 3 weeks using a rotating jar mill. Thus, milling time and the amount of material milled must be optimized for each type of mill and grinding medium.

Apr 28, 2017· Open Circuit Grinding. The object of this test was to determine the crushing efficiency of the ball-mill when operating in open circuit. The conditions were as follows: Feed rate, variable from 3 to 18 T. per hr. Ball load, 28,000 lb. of 5-, 4-, 3-, and 2½-in. balls. Speed, 19.7 r.p.m.
Disc mill SBM 200 Disc mill The disc mill can be used to finely grinding soft to hard materials with a Mohs hardness of up to 8. Grinding in the disc mill is done between two roughly toothed grinding discs. One grinding disc is stationary, the other is rotated by a geared motor, thus exerting a shearing action on the material to be broken up.

The purpose of this centrifuge is to separate solids from liquids in a slurry. The slurry is fed via an inlet pipe to the pre-thickening area of the centrifuge via openings at the center in the worm body. The main liquid will be discharged at the rear of the bowl via an adjustable overflow (weir) to obtain a clean liquid separation (filtrate).
