A ball mill is a type of grinder that uses metal balls or other grinding mediums to reduce the size of various materials. The material to be ground is placed in a cylindrical container that spins on its axis. The metal balls or grinding media inside the container hits the material and breaks it down into smaller particles.
of Ag was carried out by planetary ball mill (QM1SP2) in a agate jar using agate balls of 2–6 mm diameter. Figure 1 shows a schematic diagram of the planetary ball mill [6]. During the preparation process of flake silver powders by planetary ball mill, every time the ball mill adopts double pots symmetrically. To obtain satisfactory product,
- Motor Power: The motor power of a ball mill is an important factor in determining its grinding capacity. Ball mills can be equipped with motors ranging from 10 kW to 500 kW or more, depending on the size and desired output of the mill. - Speed: Ball mills are usually operated at speeds between 60% and 70% of the critical speed.
