numerous than the teeth on a milling cutter. Cutting speeds in grinding are much higher than in milling. The abrasive grits in a grinding wheel are randomly oriented . A grinding wheel is selfsharpening. Particles on becoming dull either fracture to create new cutting edges or are pulled out of the surface of the wheel to expose new grains.

mill. The larger particles are affected to a greater degree by the mass force, circulating around the periphery of the mill and colliding with other particles. As the particles become finer, the drag force exerts greater effects, drawing the particles with the airstream to the central outlet of the mill.

A hammer mill is typically good for grinding softer materials with Mohs hardness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materials become very abrasive; therefore, they are not suitable for highspeed hammer mills. In a typical jet mill, grinding
