Forging Steel Balls 75Mncr Grinding Media High Chrome Casting Ball
Forged steel ball:
The Forged ball is made by direct heating at high temperature and forging, and it do not need melting and casting. So this steel ball is called Forged steel ball.
1. Features of forging grinding media balls:
1). Even high hardness
2). Good wear-resistance
3). Unbreakable
4). High impact value
5). Production Capacity: 50,000mt per year
6). Low price
2. Applied fields of forged grinding balls: a) Mines; b) Cement plants; c) Power stations; d) Chemical industry
3. Raw Materials: B2; B3; B4; 60Mn;
4. Specifications of our products as follows:
