  • 5.3 GRINDING FORCES, POWER, AND SPECIFIC ENERGY

    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.

  • How to calculate the grinding time of the ball mill

    Then the minimum grinding time = 4.56/1.35=3.38min Note When the grinding time is the shortest grinding time, it is ideal when the large block is directly ground to the granule size, and there is no over grinding phenomenon. This value is only for theoretical calculation. The average grinding time on site is higher than this value.
