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.
Ball mills are used for crushing and mixing of raw materials. While rotating, the grinding media (balls, beads, pulps, etc.) and the raw material rotate along with the mill drum. The feed material is grinded as a result of the grinding media shifts and mill drum`s rotation. There are several construction types for the ball mills.
Nevertheless, ball mills can be a more appropriate choice for grinding larger sized material starting at 1/4 " or larger. It should be noted that ball mills are much larger than Attritors and therefore require a special foundation. The Attritor's design accounts for much of the difference: conventional ball mills turn the entire drum or ...

A mill ready to start a grinding operation could be around 150 t in dead weight. Thus, the initial torque on the mill shaft is very high and an electric drive motor and drive is designed to cope with it. Figure 8.11 illustrates a typical change in torque with increasing speed of motor. It can be seen that the peak torque of 140% of the running ...
The PC Hammer Mill, MTW, MTM Medium Speed Trapezium Mill and Ball Mill, and the LM, LUM Vertical Mill cover all requirements of crude powder milling, fine powder milling and ultrafine powder milling in the industrial milling field. Production of free combination from 0 to 2500 meshes can be realized.
Construction of ball mill Shell Mill shells are designed to sustain impact and heavy loading, and are constructed from rolled mild steel plates, buttwelded together. Holes are drilled to take the bolts for holding the liners. Normally one or two access manholes are provided.

The design of a ball mill can vary significantly depending on the size of the required mill, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the "lengthto- - diameter" ratio, which frequently varies from 0.5 to 3.5.
