The design of a ball mill can vary significantly depending on the size, 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 ratio "length to diameter" and this ratio most frequently varies from 0.5 to 3.5. The
Less wear takes place in rubber lined mills. The length of the mill is approximately equal to its diameter. The general idea behind the ball mill is an ancient one, but it was not until the industrial revolution and the invention of steam power that an effective ball milling machine could be built. It is reported to have been used for grinding ...

Ball Mill Length And Diameter Ratio; length / diameter ratio for ball mill - Grinding Mill China. Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits. According to the need of customers, ball mill can be either wet or dry designs.
In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

According to the ratio of length and diameter for the barrel,mill can be divided into short mill and long mill;according to the grinding media shape,it can be divided into the ball mill, raymond mill,vertical roller mill, the bat mill and gravel stone;according to the driving mode,it can be divided into central driving mill and peripheral driving mill.
How to Size a Ball Mill -Design Calculator & Formula ... Ball milling – a ball mill with a diameter of 2.44 meters, inside new liners, grinding wet in open circuit. When the grinding conditions differ from these specified conditions, efficiency factors (Rowland and Kjos, 1978) have to be used in conjunction with equation 1. In general ...
Determining the optimum diameter of grinding media used for ultrafine grinding mechanisms TATSUO TANAKA 5-12.2-27,Sumikawa,Minami-ku, Sapporo 005, Japan Published in JPTJ Vol. 31, No. 1 (1994); English Version for APT received 18 November 1994 Abstract-The ultrafine grinding rate using balls as the grinding media is analyzed as the product of the following items: the number of contact .
Ball charge loading impact on specific power. In determining the proper mill size required to meet a targeted production rate, many factors are evaluated including: length to diameter (L/D) ratio, indi.
Rod Mill. Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.
