Ball mill rotating speed when grinding ball adding rate remains constant, the useful power of ball mill varies with the rotating speed, therefore, production efficiency will also be influenced. Ball mill rotating speed need to be adjusted according to different types of ores.
Read MoreJun 01, 2009 Nowadays ball mills still dominate secondary grinding applications, but are increasingly in competition with closed circuit AG SAG mill circuits and stirred mills (Napier-Munn et al., 1996). At product sizes finer than 80 passing 75 μm, the efficiency of ball mill grinding rapidly.
Read MoreApr 15, 2019 The larger feed size, the work that the ball mill needs to do on the ore. To achieve the specified grinding fineness, the workload of ball mill will be increased inevitably, and then, the energy consumption and power consumption will be increased accordingly.
Read MoreJul 08, 2019 The grinding efficiency of ball mill is low, the treatment capacity is low, the production energy consumption is high, the product fineness is unstable and so on, which are the problems that most concentrators will encounter. How to effectively improve the grinding efficiency of ball mill is an important problem. This article summarizes 10 ways to improve efficiency, if you are worried about.
Read MoreMay 22, 2019 Therefore, in the rolling ball mill, the grinding efficiency is increased as the ball diameter decreases. It has been proven that the highest grinding efficiency can be obtained with a small ball of .mm diameter. However, the ball diameter is too small to wear too fast, and it is also difficult to discharge due to the small gap of the ball.
