Effects of grinding parameters on product fineness in jet
1998-11-1 Mills often used for ultra fine grinding are the attrition mill and the jet mill [1,2]. In cases where dry grinding, or a very narrow particle size distribution for the product, is needed, jet mills are mostly used. The jet mill is a stutic machine which does not have any grinding media.

Impact of grinding aids and process parameters on dry
2018-7-15 The impact of the stress conditions inside the mill on the grinding result was examined by varying the media size d GM, grinding media density ρ GM and stirrer tip speed v t.Therefore, three different kinds of grinding media materials as well as a number of media sizes were investigated in this study (see Table 1), while the grinding media filling ratio ϕ GM was kept constant at 40%.

With earlier planetary ball mill designs, the kinematics of the mills were always perfected to ensure an optimal launching point for the grinding elements as learned from the conventional ball mills. The grinding drum of a ball mill functions in earth's gravity field, whereas the movement of a ball in the planetary ball mill is due to the superposition of various centrifugal and coriolis forces.
