What is the performance of HPGR studs

The cemented carbide HPGR studs roller has been widely used in the raw material roller press of the cement industry. Due to its stable production operation rate, long service life and other advantages, it is favored by the cement industry. The stud for roller press is made of tungsten cobalt cemented carbide, with tungsten carbide (WC) as the matrix and cobalt (CO) as the bonding phase. It is a wear-resistant material with high hardness, high strength and good impact resistance made by powder metallurgy process. The HRA hardness of cemented carbide stud is about 87, which can greatly improve the service life and working efficiency of the roller press, and has high wear resistance.

The main performance indexes of tungsten cobalt cemented carbide stud include hardness, bending strength, impact toughness, bending magnetism, etc. Generally speaking, the higher the material hardness, the better the wear resistance; The higher the bending strength, the better the fatigue resistance; The impact toughness of cemented carbide stud is better, so the fracture resistance is better. There are many factors that affect the performance indexes of tungsten cobalt cemented carbide studs. For example, the higher the cobalt content, the higher the bending strength and impact toughness, and the lower the relative hardness and bending strength.

Therefore, the service life of the roller press can be greatly improved only by selecting the cemented carbide studs that meet the performance indicators of specific application conditions. Z Well, the proportion of raw materials shall be determined according to the operating conditions of the cemented carbide stud.
