TYPES OF GRINDING WHEELS

Sand stone (solid quartz) These are relatively soft. These cannot be used for grinding of hard material and at faster speed. Emery is a natural aluminium oxide containing 55 to 65% alumina, rest are iron oxide and impurities. Corundum : If percentage of aluminium oxide is more, ranging from 75 to 95% then it is called corundum.

The oldest machining process at the beginning of “Stone

•Free sand was applied between two moving parts to remove material and shape the stone parts. Grinding: •Removing of metal by a rotating abrasive wheel. (Very high speed, Shallow cuts) •the wheel action similar to a milling cutter with very large number of cutting points. •Grinding was first used for making tools and arms. SURFACE GRINDING: Depth of Cut: 2-5 thou, 50-125 microns Work

TECHNICAL NOTES 8 GRINDING R. P. King

8.1.1 Grinding action Industrial grinding machines used in the mineral processing industries are mostly of the tumbling mill type. These mills exist in a variety of types rod, ball, pebble autogenous and semi-autogenous. The grinding action is induced by relative motion between the particles of media the rods, balls or pebbles. This motion can be characterized as collision with breakage
