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.

Answer (1 of 2): It's more and less same as the flour mill if I talk about bowl mill. This is simplest diagram of coal mill. The crushed coal (coming from primary crusher) is stored in the cylindrical shape thing known as Bunker which is exactly on top of the mill to introduce coal into the pul...

A vertical spindle mill is also designed for pressurized and suction type requirements. Boiler designers use this type of mill for poor quality coal as this type of mill rejects foreign materials like stones and other high density materials. The power consumed by the mill per ton of coal ground is only two-thirds of the ball mills.

The plants opened more than 50 years ago and together employ about 320 full-time workers and 170 contractors. They generate enough power for perhaps 1.5 million homes, according to industry...
