Figure Displacement of balls in mill. where D m is the mill diameter in meters. The optimum rotational speed is usually set at 6580% of the critical speed. These data are approximate and may not be valid for metal particles that tend to agglomerate by welding. The minimal magnitude of ball size is calculated in millimeters from the equation:

5. Ball milling is a method of production of nano materials. This process is used in producing metallic and ceramic nano materials. These mills are equipped with grinding media composed of wolfram carbide or steel. Ball mills rotate around a horizontal axis,partially filled with the material to be ground plus the grinding medium.

Hammer Mill Principle, Construction, Working, and Advantages

Hammer Mill Principle, Construction, Working, and Advantages

Hammer mill works on the principle of impact between rapidly moving hammers mounted on a motor and the material to be milled. As the hammers revolve at peripheral speeds reaching 10, they direct themselves towards the radial directions and hit the dropping feed breaking its particles into small fragments.

The working principle of the hammer mill is simple to understand. The principle is illustrated in Fig. 1 (a). It only requires choosing an appropriate motor, crushing hammers/knives and material to be crushed. It operates on the principle of impact between rapidly moving hammers mounted on the rotor and the stationary powder bed.

For a ball mill to work, critical speed must be achieved. Critical speed refers to the speed at which the enclosed balls begin to rotate along the inner walls of the ball mill. If a ball mill fails to reach critical speed, the balls will remain stationary at the bottom where they have little or no impact on the material. Ball Mills vs ...
