A ball mill consists of a hollow cylindrical chamber (Fig. 6.2) which rotates about a horizontal axis, and the chamber is partially filled with small balls made of steel, tungsten carbide, zirconia, agate, alumina, or silicon nitride having diameter generally 10 mm. The inner surface area of the chamber is lined with an abrasion-resistant material like manganese, steel, or rubber

As far as the grinding media are concerned, common practice is to use hardened high carbon-high chromium steel balls (4 to 12 mm diameter), normally specified for ball bearings. Stainless steel balls have also been used. When it is necessary to minimize iron contamination in the charge, balls of tungsten carbide have also been used

modelling of the high-energy ball milling process

modelling of the high-energy ball milling process

In this paper, the milling parameters of high energy ball mill (Fritsch Pulverisette 7) like vial geometry, number and size of balls and speed of the mill were modelled and discussed. Simulations through discrete element method (DEM) provide correlation between the milling parameters. A mathematical model is used to improve and develop this process

(pdf) the effect of intermediate stop and ball size in

Cooling the diminishing of the powder size [3]. A larger ball seems vial by intermediate stops will decrease the temperature more beneficial to the milling of steel chip into powder of the vial, and gives less ductile behavior to the steel due to the large impact energy during the falling of the powder, which are then easily work-hardened and
