50mm Ball Mill Grinding Media For Copper Mining, 60Mn, B2, B3
Description
Forged steel balls are divided into carbon steel grinding steel balls, manganese steel grinding steel balls and special alloy steel grinding steel balls. Forged steel balls are one of our superior products. The steel balls with diameters of 20-80mm and 90-150mm are respectively advanced Automatic hot rolling production line and semi-automatic roll forging production line. Relying on advanced production technology and fully automatic production equipment, while the production efficiency is improved, the finished steel balls have uniform gradient distribution, uniform hardness, and have excellent mechanical properties that are not broken, cracked, and round during use.
(1) 45# steel wear-resistant steel ball
A commonly used forged steel ball, widely used in large-scale ball mills such as mineral processing, power plants, steel mills, and chemical plants. The diameter range is 20-150mm, we can also customize according to customer requirements, the main product performance is as follows:
