 — Abstract. Muscovite, wollastonite and kaolinite were wet attrition ground in a pilot-size stirred ball mill (continuous type) as well as a vibratory mill (batch. It is shown that the vibratory mill (SWECO) is much less efficient than the stirred mill (DRAIS), at least …

of the stirred ball mill. The parameters studied include mill peripheral speed (9.3 to 16 m/s), media type (steel shot, glass beads, alumina balls and crushed quartz), bead size (-2.7 +2.3 mm,-3.2+2.8 mmand-4.3 +3.7 mm) and the number of passes. The stirred mill feed flow rate to the stirred mill was fixed at 0.18 m3/h.

 — The results showed that the milling stresses were transferred mainly by impact in the rotary ball mill (RBM), by attrition in the vibratory ball mill (VBM), and by a combination of impact and attrition in the stirred ball mill (SBM). In each mill type, the particle size reduction was always quicker and less energy-intensive on bark (a brittle ...

 — The probability P s depends on the type of grinding process. ... Grinding experiments were performed in a 0.6-l horizontal, stirred ball mill (Drais Perl-Mill Eirich-Gruppe). The mill consists of a glass chamber and a stirrer shaft fitted with four stainless steel agitator disks. The agitation speed was controlled by a pulley arrangement ...

 — It was found that the ball mill consumed 54.67 kWh/t energy to reduce the F 80 feed size of 722.2 lm to P 80 product size of 275.4 lm while stirred mill consumed 32.45 kWh/t of energy to produce ...
