Thermal power and steel
Coal crusher and mill parts for power stations and wear parts for the material-handling lines of steel plants.
A coal-fired station wears out its crushers and its mills; a steel plant wears out the crushers, chutes and spouts that handle its raw materials. Both need abrasion resistance where material slides and toughness where it strikes, specified part by part.
Coal handling
Hammer crushers size coal before the mills. Chutes guide it between conveyors. Parts take impact and abrasion from coal, shale and stone.
Coal grinding
Vertical bowl and roller mills and tube mills grind coal to fine powder for the boiler. Sliding abrasion dominates, so white irons last longest.
VRM rollers
- Fails by
- Profile wear across the face
- Usual grade
- High-chromium iron, Ni-Hard

Steel plant material handling
Ore, coke and flux are crushed, conveyed and fed through chutes and spouts that wear by impact and sliding, sometimes while hot.
