Tungsten carbide edge block used in HPGR in iron ore processing plant
Carbide HPGR Bits:
Our HPGR bits are made with typical tungsten carbide, which ensure long wear life and consistent quality. This means lower operating costs, less down time for machine maintenance, and a more predictable wear life. Close attention is paid to quality control ensuring our bits fit properly. Our replacement HPGR bits are guaranteed to meet or exceed the OEM specification for fit, material grade and performance unless otherwise stated. Our range includes bits to suit the leading brands, including Metso, Weir and more.

Manufacture characteristics of product
HPGR technology working principle is that two counter-rotating grinding rolls expose a column of material to high pressure, which is distributed across the gap between the rolls. Inter particle comminution is the HPGR specific grinding process in which material particles are crushed and ground within the compressed material bed and not by contact with the roll surface. Feed material can be smaller than the gap, which is an important distinction as compared to crushers.
As pre-grinding equipment before ball mill or form complex grinding system with ball mill in the field of mineral separation, HPGR crushers are widely used in grinding cement clinker,limestone,bauxite,iron ore.

Production Process of Tungsten carbide pin HPGR
To ensure the quality and the requirements of the drawings can be met before mass production
1st:, Start to prepare the RTP powder as per customer’s requirement with our wet-grinding machine
2nd, Before mass production, do a trial pressing and sintering using mould,
3rd, Check the appearances and the sizes of the samples with micrometer, projectors etc.
Test process of high lifetime Cemented Carbide button stud pins HPGR for breaking stones formations
1st,Mass production, press the raw materials to shape blanks,
Notes: all carbide stud pins blanks must be passed by semi finished inspection
2nd,Sinter blanks to finish (HIP) and finished products inspection,
Notes:10 sets of vacuum sintering furnace and 2set of HIP in the factory ensure the best quality and production capacity.
3rd,Cleaning/tumbling to make the carbide stud pins clean and nice surface.
Our Main products include : Carbide teeth,Carbide ball and seat, Carbide plates for agriculture wear parts, Carbide gipper, Strips, Bushings, Seals ring, Brazed tips, Nozzles, End Mills & Drill Bits, CNC inserts, Rotary Burrs, Grits, Customized carbide cutter: Woodworking tool cutter, V-cutter, mining tool, Any customized carbide products are acceptable.
