Ball milling steel balls are a type of grinding medium used in cylindrical ball mills to grind ore blocks. They are widely used in grinding industries such as iron ore and non-ferrous metal mining beneficiation plants, cement plants, thermal power plants, refractory material plants, steel plants, and phosphate fertilizer plants. During the grinding process of the ore block, the ball mill ball continuously wears down and becomes smaller until it fails, resulting in significant consumption. At present, China consumes about 4 million tons of steel balls annually, mainly cast iron balls and forged steel balls.

During the grinding process of the ore block, the ball mill ball continuously wears down and becomes smaller until it fails, resulting in significant consumption. At present, China consumes about 4 million tons of steel balls annually, mainly cast iron balls and forged steel balls. The diameter of the ball mill steel ball commonly used for specifications isΠ 20mm~Φ 125mm, the maximum steel ball diameter used for ultra large ball mills isΠ 130mm~Φ 150mm. The production process of ball milled steel balls mainly includes casting iron balls, forging steel balls, and rolling steel balls. The advantages of the casting iron ball process are simple equipment and low investment. Easy to master production technology and operation; For orders with multiple specifications and small batches, arranging production is easy and flexible. Process disadvantages: There are many casting defects (such as pores, sand holes, inclusions, surfaces, cracks, etc.); Low density and low specific gravity; The metal grains are coarse and the impact toughness is poor (generally 3-7J/cm2); High energy consumption and low metal yield& It is very difficult to cast small balls below 40mm Phi.
