Similar to the ring and ball mill, the vertical spindle roller mill uses large "tires" to crush the coal. These mills are usually found in utility plants. Raw coal is gravity-fed through a central feed pipe to the grinding table where it flows outwardly by centrifugal action and is ground between the rollers and table.
Royton Ring Mill was a cotton mill in Royton, Greater Manchester.It was built in 1908 and extended in 1912. It was taken over by the Lancashire Cotton Corporation in the 1930s and passed to Courtaulds in 1964. Production finished in 1966. It was extended again in 1969 and used for other purposes.

LP-16 Softening Point Ring and Ball Apparatus determines the softening point of asphalt, coal tar pitch and other viscoelastic bitumens in the range of 30°—157°C (86°—315°F). The unit simultaneously tests two samples for optimal compliance with standard test procedures. Steel balls are placed on top of bitumen specimen disks in test rings in a bath.
Grinding in small plants, as in larger installations, has proven to be the most costly of all unit operations from both capital and operating standpoints. Therefore, grinding deserves the most scrutiny of all operations during the design procedure. A recent survey by a major grinding mill manufacturer reveals that more than 80 autogenous or semi-autogenous mills having between 100 and 1,000 ...

which enables us to see how the Attritor fits into the family of mills. For example, ball mills use large media, normally 1/2” or larger, and run at a low (10-50) rpm. The other mills, such as sand, bead, and horizontal, use smaller media from 0.3mm to 2mm, but run at a very high rpm (roughly 800-1200).
The impact energy of the milling balls in the normal direction attains a value of up to 40 times higher than that due to gravitational acceleration. Hence, the planetary ball mill can be used for high-speed milling. Schematic view of motion of the ball and powder mixture.
