Goldpro--- THE GRINDING BALLS PRODUCTION PROCESS:
|
Inspection of the raw materials
the raw materials for grinding balls are round bars.
The round bar be inspected strictly before entry into processing line.
The inspection samples of round bar stock in our laboratory for reference. |
Heat of raw materials
The raw materials heat by the gas, which have high energy and clean.
Temperature is one important factors which effect the hardness of grinding balls directly.
Our modern heating equipment make the accurate control of temperature for steel bar |
Hot-rolling and Forging technology
Hot rolling technology imported from Chinese Academy Engineering , main processing 20 25 30 35 40 50 60 mm Diameters Grinding balls.
Forging technology is mainly used for processing Grinding balls which Diameter is 70 76 80 90 100 120 130 140 mm. |
