Dec 10, 2019 Cement ball mills can be divided according to discharge method grate ball mills and overflow mills, and can be divided into wet mills and dry mills according to their processing conditions. Cement mill structure Ball mill is mainly composed of feeding part, supporting frame, rotary part, discharge, transmission, lubricant and cooling part.
Mill performance is based on mill diameter and length only increases or decreases capacity. The Slice Mill is simply a mill of the same diameter as the production mill but much shorter. A Slice Mill of 72 diameter by 12 wide would replicate the result of a normal production, mill 72 in diameter as 120 long.
Grinding in Ball Mills Modeling and Process Control ... An important characteristic of an industrial ball mill is its production capacity ... selection of a fraction of the material to be broken,
The bigger ball in relation to the optimal one will have an excess energy, and consequently, the smaller ball mill has less energy necessary for grinding. In both cases, the specific power consumption increases and the grinding capacity decreases Concha et al. 1992
The experiment was conducted in the State Key Laboratory of Process Industry Automation of China, using a simulation platform developed by Lu et al. 2014. The experiment process is that the operators control the value of three grinding variables to achieve a target grinding particle size GPS on the ball mill grinding circuit simulator see Figure 1.
