Hardfacing — Wear resistant surfaces deposited on the base metal or on build-up deposits extend service life. Hardfacing is usually limited to one, two, or three layers. Consumable Selection Welding material selection depends upon three major factors: 1. Base Metal — Primarily affects the choice of build-up materials. a.
High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size. More
