Hardfacing is a low cost method of depositing wear resistant surfaces on metal components to extend service life. Although used primarily to restore worn parts to usable condition, hardfacing is also applied to new components before being placed into service. In addition to extending the life of new and worn compon-
In 1954 a Jet Pulverizer was developed in which operates like a Vertical Pulverizer only the item is pulverized by the high speed air action. For example, forcing coal against coal. Bowl mill. Similar to the vertical roller mill, it also uses tires to crush coal. There are two types, a deep bowl mill, and a shallow bowl mill. High speed
