The scraper conveyor is the key conveying equipment for fully mechanized coal mining. Wear failure of the chute is the main form of failure of the scraper conveyor. In this study, the discrete element method (DEM) was combined with the wear model. The wear mechanism and wear regularity of the chute were explored by tracking the changes in the position of coal particles during the wear process.

A coal bunker is a large storage facility for coal in a power plant. Coal bunker scraping is a routine process of cleaning a coal bunker. Coal from bunker flows to the pulverizing mill. The continuous flow of coal is necessary for optimal operation of the power plant. Coal is expected to flow by gravity. While this arrangement works in dry coal ...
The coal mill scrapers will usually sweep the fuel pieces around to the debris chute and discharge them; however, a fire is likely to occur if a coal buildup occurs at the hot air inlet to the mill.

MPS mill for solid fuels and other MPS mills lies in its pressureshock resistance. Mill and classifier housing, feed unit and expansion joints are designed pressureshock resistant. To avoid accumulations of coal dust as a source of spontaneous combustion, all surfaces in the grinding and classifying zone are vertical or inclined.
The main source of heat is coal burning. Coal is fired as a main fuel (100%) in the rotary kiln and calciner chamber. Coal is burnt to provide the required heat for calcination and to convert the kiln feed into clinker. This red hot clinker further goes to clinker cooler for cooling the clinker from 1400 degrees to 200 degrees.
