Manufacturer High Pressure Grinding Roll Tungsten Carbide Hpgr Stud Pin

Product Description

Feature:
Tungsten Carbide Studs for HPGR Rollers

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 Hongtong provide quality carbide studs with good wear resistance and high compressive strength, which can satisfy the requirements of different conditions.

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.

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.

Application:
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.
