This four-horse mill is based on a central, vertical, heavy, 10 feet (3.0 m) high, oak axle, with its base pivoting on an iron framework set in the middle of the gin gang floor. Its top end pivots under the mill's own tie beam (if it didn't, it would fall over) but the tie beam cannot rest on the pivot, or the mill would not turn.

Depending on a number of factors including coal properties, boiler efficiency typically ranges between 87% and 89% while firing coal. The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal ...

The operation state of coal mill is related to the security and stability operation of coal-fired power plant. In this paper, a fault diagnosis method of coal mill system based on the simulated typical fault samples is proposed. By analyzing the fault mechanism, fault features are simulated based on the model of coal mill, and massive fault samples are obtained.
