Product Description
Product Features:
1. Spherical crown was made of hemisphere design, to avoid stress concentration cause to steel damaged.
2. Corner with arc transition, to avoid the damage during production, transportation, installation, and using procedure.
3. HIP sintered, good product density and high strength.
4. Apply special technology to relieve stress of product surface after processing, at the same time improved surface hardness.
5. Product surface coated with a layer of grease to avoid oxidation.
Product Application:
1. Grinding bulk material.
2. As pre grinding equipment before ball mill or form complex grinding system with ball mill in the field of mineral separation.
3. It widely used in grinding cement clinker, limestone, bauxite, iron ore.
The method of installing the carbide stud is as follows:
1. Surfacing welding 2. Cold pressing 3. Hot inlay 4. Adhesive
With the advantages of high crushing efficiency, low energy consumption and high material yield, high-pressure roller press is gradually recognized by the market. The running status of the roller press is determined by the performance of the carbide roller press stud.

Production Process:
To ensure the quality and the requirements of the drawings can be met before mass production:
1. Start to prepare the RTP powder as per customer's requirement with our wet-grinding machine.
2. Before mass production, do a trial pressing and sintering using mould.
3. 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:
1. Mass production, press the raw materials to shape blanks.
Notes: all carbide stud pins blanks must be passed by semi finished inspection.
2. 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.
3. Cleaning/tumbling to make the carbide stud pins clean and nice surface.
