A minimum airtocoal weight ratio of :1 is desired at full load. The ratio could be higher at lower loads (more air per pound of coal). Failure to provide adequate airflow through the mill can result in spillage of coal. The exhauster discharge pressure is an indicator of flow and velocity through the coal piping.

A tube mill is a revolving cylinder of up to five diameters in length used for fine pulverization of ore, rock, and other such materials; the material, mixed with water, is fed into the chamber from one end, and passes out the other end as a slurry . Both types of mill include liners that protect the cylindrical structure of the mill from wear.

The terms colliery and coal breaker are often used interchangeably and often imply that they are one in the same. A colliery in reality is where the coal is dug and can often refer to the mine itself and its associated property. A coal breaker is the coal preparation plant. Thus said, it should be noted that all collieries did not have coal ...

According to the World Coal Association, the process responsible for the formation of coal began 360 to 290 million years ago. With this in mind, it would seem absolutely impossible for any human artifacts to be found within this ancient substance; but incredibly, many items have reportedly been found in such deposits, either buried inside the coal itself or found buried deep down within coal ...

The coal was originally raised by jackrolls and later by horse gins. In 1663 Sir John Lowther drove a long level from Pow Beck in a westerly direction under Monkwray and into the Bannock Seam. This level drained an area sufficient to serve the needs of the coal trade until nearly the close of the 17th century.
