Products Inquiry ball size determination for cement mill design. Making a Ball MillYouTube. 2018 03 31 The milling of the materials is a very useful procedure in various domains in life as well as in the constructive domain.
Consulting ServiceAn experimental laboratory scale ball mill available at the University of Lubumbashi was used in this research work. The ball mill measured 0.305 m in diameter and 0.127 in length. It was driven by an asynchronous motor rated with power close to 10 kW. A schematic of the experimental laboratory ball mill used is shown in Fig. 3.
Get QuoteMill Critical Speed Determination. The Critical Speed for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface. This is the rotational speed where balls will not fall away from the mill's shell.
