Grinding Ball Example. The SAG Mill will process 1 Diamond Ore at the cost of 3,600 µI. It will produce 2 Diamonds, has a 25% chance of producing an auxiliary Diamond, a 15% chance of producing Cobblestone, and a 5% chance of producing Coal Powder. If you use a Dark Steel Ball, then the recipe only needs 70% of the base power, down to 2,520 µI.
Grinding balls for mining are generally used to break down secondary materials such as rock, cement and stone during the extraction of ores and metals.

Our ball mill grinding products apply the ancient principle of ball grinding to the industrial needs of the modern world. Many different industries can benefit from the grinding action that these mills offer: they are suitable for both dry and wet grinding as well as cryogenic grinding, and are commonly used for mixing or grinding chemicals, ores, paints and ceramic materials.
The mill's action — for example, the motion of a grinding bowl in a high-speed planetary ball mill — generates high-energy shear forces to fracture already small particles into nanoparticles as they circulate with the grinding media. The smaller the milling media size, the smaller the final particle size.
Steel balls used in grinding medium are used in grinding of ore to fine dimensions in ball mills.Mill balls are used in semi-autogenous and ball mills. Semi-autogenous grinding; is a type of grinding carried out with a small amount of ball charge and with the help of bigger parts crumbling the smaller parts of ore. Our company producing high ...
The main reason ball mills are not utilised for fine grinding is the perceived poor energy efficiency generally experienced when grinding to fine sizes. However there is a trend towards ball mill grinding for product sizes below the traditional ball mill cut-off of 45 μm.
