Ball mill
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

Pulverizing Mills Deepakkumar Yadav
4. Hammer mills : The principle of operation of hammer mill is shown in Figure C. These mills have swinging hammers or bars, into the path of which is fed the coal to be pulverized. Grinding is done by a combination of impact on the large particles and attrition on the smaller ones. Hot air is given to dry the coal.Ball-race mills and Loesche roller mills were used. Three types of interactions between mineral particles and grinding components, Fn-normal force, Ft-tangential force, m-mass, v-speed.Technique to Investigate Pulverizing and Abrasive Performance of Coals

Breakage and separation mechanism of ZGM coal mill based on parameters optimization model. International Journal of Mining Science and Technology 2014, 24 (2),285-289.It was found that the ball mill consumed 54.67 kWh/t energy to reduce the F 80 feed size of 722.2 µm to P 80 product size of 275.4 µm while stirred mill consumed 32.45 kWh/t of energy to produce the product size of 235.6 µm. It also showed that stirred mill produced finer product than the ball mill at around 40% lesser consumption of energy.Effect of particle properties on the energy-size reduction of coal
