HPGR Roller with Stud to Replace of Surfacing Welding is a World Trend.
As one of the key parts of HPGR, Studded roller technology has been proven to be successful not only in the cement but also mining industry.
With advantages of more productivity and less energy cost, carbide stud is used in HPGR in recent years.
The technology of hard-alloyed stud, or ‘carbide pins’, embedded in the roller surfaces is a revolution in mining industry due to studded roller’s good wear resistant character. In general, stud rolls’ working life is 5-10 times longer than that with surfacing welding and can meet wear protection requirements in working condition.
