Tons of coal, slurries, ash and emissions moving through the plant around the clock cause wear that can result in frequent interruptions of production. Greenbank’s alumina ceramic linings prevent this problem, extending service life of equipment by as much as 15 times.

In addition, alumina ceramic costs much less than Ni-Hard casting, a commonly used alternative and while alumina ceramic costs more than A.R. steel, its wear resistance is far superior.

In Coal Preparation Plants
Greenbank’s alumina ceramic linings are available in standard or custom-engineered sizes, shapes and pre-engineered designs in plain, weldable and mechanically interlocking tiles. Greenbank also provides silicon nitride bonded silicon carbide for lining equipment operating in ambient temperatures for intermittent use up to 2900°F (1600°C).
