equipment design equation ball grinding mill. Nov , in addition to the ball mill, simulation of various milling equipment such as centrifugal mill , stirred mill and planetary mill were also studied for example, mori et al studied the correlation between impact energy and grinding rate for a wet ball mill and reported that the grinding rate can be predicted through the measured impact energy
2010; 2011). For each grain size there is an optimal ball size (Trumic et. al., 2007). 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
Ball mills, which grind coal to a target size prior to boiler combustion, are important auxiliary equipment in thermal power plants. Their coal grinding efficiency is closely related to the economy of the power plant, as discussed by Masiuk, et al. [].The control requirement for a pulverizing system is to guarantee that the coal load in the ball mill is close to the optimum level.

Oct 01, 2020 Since there is a strong correlation between load behavior and mill power, load behavior is an essential operating factor that can even be used to control a mill (Austin et al., 1984).Grinding media directly affects the load behavior and, consequently, the performance of industrial mills in terms of product size, energy consumption, and grinding costs.
The mill used for carrying out the grinding tests was assembled with 1020 carbon steel, diameter and length equal to 254 mm (10 ). Tests were conducted at 70% solids and 33% ball load, according to three different ball top sizes, as well as three different mill rotation speeds. Tests included mill shells with lifters and a smooth one.
