High-Pressure Grinding Roll (HPGR) FlangeThe High-Pressure Grinding Roll (HPGR) flange is a critical component in the assembly of HPGR systems, which are widely used in the mining industry for efficient ore processing. The flange serves as a robust connection point, ensuring the structural integrity and operational reliability of the grinding rolls under extreme pressure conditions. 1. Design and FunctionalityThe HPGR flange is engineered to withstand high mechanical stresses and abrasive wear, common in mineral processing environments. Typically manufactured from high-strength alloy steel or other durable materials, the flange is precision-machined to meet tight tolerances. Its primary function is to secure the grinding roll to the machine's frame, maintaining alignment and stability during operation. The flange also facilitates the transmission of forces generated during the high-pressure grinding process, ensuring consistent performance and minimizing downtime. 2. Key Features
3. ApplicationsHPGR flanges are integral to the mining industry, particularly in processing hard rock ores such as gold, copper, and iron. They are essential for maintaining the high-pressure environment required for efficient comminution, reducing energy consumption compared to traditional grinding methods. The flange's reliability directly impacts the overall efficiency and throughput of the HPGR system. HPGR Carbide Flange for high pressure grinding roller
Welding
Welding to the base plate is possible, but not recommended, except for stud welding (AS 1554.2), as this may compromise the bond between the base material and tiles. Benefits
·Vacuum brazed bond exceeds typical bond strength for rubber or direct bonded ceramics.
·Mild steel base plate can be easily stud welded.
·Extremely hard liners for extremely abrasive conditions.
·Personalized customization can meet the on-site use of different customers
Applications:
·Applications involving severe sliding abrasion and medium impact, such as
·Chutes
·Deflector chutes
·Ore Handling Systems ·Liner Plates
·Hoppers
·Conveyor skirts
·Conveyor drag plates
·HPGR feed cheek plates
·HPGR flange

ZZ OLD CRAFTSMAN is not only produce the carbide edge blocks, we also produce the HPGR flange, wear liners for the HPGR feeder chute.
Carbide wear liner is the super extreme in wear resistant liners and is designed for applications that experience severe abrasion, where standard wear plate is ineffective. Carbide wear liner is available with Tungsten Carbide tiles, in a range of thickness up to 30mm, vacuum brazed to a mild steel backing plate. We are good at customized design, from the shape and carbide grade of the product. If you have a new requirement or want to upgrade your present material to get a much longer life, please contact us.
Base Material
The standard base material is mild steel plate of varying thickness, ensuring the finished parts are readily weldable.
Carbide Tiles Properties, we have many grades for the different usage, and we can design new grades according to different customers' requirements to meet their on-site needs. Below are some standard grades we are using, and the brazing strength is higher than 220MPa.
