involve grinding). With Lloyd's ball milling book having sold over 2000 copies, there are probably over 1000 home built ball mills operating in just America alone. This article borrows from Lloyd's research, which was obtained from the commercial ball milling industry, and explains some of the key design criteria for making your own ball mill.
Equation 1 to drive the corrected power requirement (Rowland, 1982). The equation for Third Theory of Comminution Bond's was originally developed for use with conventional crushing and grinding circuits (crusherrodball mill or crusherball mill). By the 1970s, the application of conventional tended to be limited to relatively low capacities.
The "effective mill power" (EMP) can then be defined relative to the total mill power (TMP). EMP is the percentage of total mill power draw delivered to the "coarse" ore and is defined as EMP = TMP x CSEff (1) The ball mill circuit functional performance equation. A practical measure of a .

Popular Answers ( 2) Considering that ball bed has a porosity of 40 %, the actual ball volume is considered to be 2124 % of the empty mill. Now, in order to get an efficient milling action, 80110 % of the pores in the ball bed must be filled with the actual particles to be ground. Then, by doing simple calculation, the particles occupy of the mill volume.
this plant includes one SAG mill in a closed circuit with a vibrating screen and one ball mill with a size classification system of, decrease of consumed energy and costs Thus,, mill was also obtained and explained in Equation 2[3],.
The ball mill sizebysize (energy specific cumulative) grinding rates (k values) were calculated as shown in Fig. 5. In this case, mill power at the pinion was 955 kW (1,280 hp) and tonnage through the mill was t/h (Fig. 2) giving a perpass specific energy of 955/ = kWh/t.
