The carbide studs is made of tungsten cobalt cemented carbide sintered at high temperature, and the hardness is as high as HRC67. The biggest characteristic of the roller surface of the carbide suds is the self-generated lining plate. In the process of rotation of the roller, the gap between the studs and the studs is filled by the fine particles in the material, so as to form the material lining to protect the base material of the roller sleeve. In the actual use of the material should ensure that there is a certain amount of moisture, which is more conducive to the formation of material lining.

High Pressure Grinding Roller is an energy-efficient crushing equipment of new technologies. High performance of carbide stud extends the life of High-Pressure-Grinding-Roller. Zhuzhou Jinxin provides quality carbide studs with good wear resistance and high compressive strength, which can satisfy the requirements of different conditions.

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

Tungsten-cobalt carbide stud has the advantages of wear resistance and high hardness, but the anti-shear ability is slightly weak. There will also be damage in the process of use, such as fracture or accelerated wear and tear. In the production and operation of the studded-roller, the studded-roller is subjected to severe high stress abrasive wear, shear force damage and long-term fatigue damage. In the operation process, the studded-roller will fracture, peel off and serious wear problems, thus affecting the output and service life of the roller press. The common reasons for the damage of tungsten cobalt carbide stud are summarized here.
