Wear Components For Coal Grinding

Grinding elements take the wear and tear of coal

The portions of the grinding elements that are exposed to the pulverised coal/air mixture from the pulverised coal being suctioned off the bowl are also subjected to abrasion or erosion. Erosion is a velocity related wear component in which the force of erosion acts at an acute angle to the grinding
