Tungsten Carbide Stud Z2 – HPGR Wear Parts for Cement Equipment
Tungsten carbide stud Z2 is designed for high-pressure grinding rolls (HPGR) in cement and mining industries. It offers high wear resistance and excellent impact strength to protect roller surfaces from abrasive wear and extend equipment service life.
Tungsten Carbide Stud Typical applications include:
High-pressure grinding rolls (HPGR), cement roller presses, mining crushers, and other heavy-duty grinding equipment.
Features:
- Adopting a hemispherical design to avoid stress concentration and damage to the steel body.
- Designing arc edges to avoid damages during production, transportation, installation and using.
- Adopts pressure sintering to ensure good density and high strength.
- Applying special process to remove the surface stress of the product after processing, and at the same time increase the surface hardness.
- A layer of grease is applied on the surface of the product to prevent surface oxidation of the product.
