· A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse ...
This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types: grid type ball mill and overflow type ball mill.
The ball impact energy on grain is proportional to the ball diameter to the third power: 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding (wet/dry). None of the characteristics of the material being ground have any influence on K 1.
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. This is a good starting point for anyone interested in making their ...

the effect of any ball mill design or operating variable. Along with plant testing difficulties, only fairly large changes in circuit performance could be linked to a media size change. • Population balance modelling was deemed unsuitable for this purpose. As noted by Meloy et al., (1990), any number of different breakage rate curves can be derived from the same mill feed and product sizing ...
· Ball mills are a special instrument used to break up hard solids into a fine powder. They are similar to rock tumblers in that the instrument is a rotating container filled with heavy balls to grind the substance into powder. Ceramic material, crystalline compounds, and even some metals can be ground up using a ball mill. Using a motor, container, belt, caster wheels, .
ball mill to produce the final cement product [3]. Figure1shows the percentage of energy usage in various stages of the cement manufacturing unit [4]. Under this scenario of extensive energy usage in clinker grinding, the cement industries not only require the proper mechanical design aspect of the grinding unit but also necessitate suitable and e cient controllers that result in a .

· I'm currently working on a project that requires me to design a ball mill for crushing Sulphur powder. The goal is to reduce 10kg of powder from 500 microns to 10 microns in around 5 hours. The drum size is around 80L does that sound right? And it sounds like balls will be used as the grinding media due to the initial size of the powder.
