section contains machining data tables and equations to calculate approximata power, speed and feed rates. For grinding applications it is recommended that a grinding wheel manufacturer be conctacted to determine the proper safe operating speeds and power requirements to ensure that the grinding wheel is not operated above the maximum rated speeds.

Comminution is an important process in mineral processing, power plants, cement production and pharmaceutical industries. It is costly and an inefficient process in terms of energy requirements and steel consumption related to grinding media and liners. Spherical grinding media are predominantly used in final stages of ore grinding. The

5.3 GRINDING FORCES, POWER, AND SPECIFIC ENERGY. Forces are developed between the wheel and the workpiece owing to the grinding action. For plunge grinding operations, as illustrated in Figure 5-2 for straight surface and external cylindrical grinding, the total force vector exerted by the workpiece against the wheel can be separated into a tangential component F t and a normal component F n.
