Grinding PPT SlideShare
Grinding: Grinding is a process of removing material by abrasive action of a revolving wheel on the surface of a work-piece in order to bring it to required shape and size The wheel used for performing the There are many types of grinding: “precision” and “rough,” internal, external, surface, centerless; using wheels or belts; and conventional or “super” abrasives.

size reduction PPT SlideShare
If n=2.0 equation (2) becomes Rittinger’s theory. 24. Rittinger’s theory According to this theory energy E required for size reduction of unit mass is directly proportional to the new surface area produced. E=KR (Sn Si) . (3) Where Si = initial surface area Sn = new specific surface area KR = Rittinger’s constant.Difference between grinding and milling The abrasive grains in the wheel are much smaller and more 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 self-sharpening.abrasive machining processes IIT Kanpur

Fixture Design SME
table is the preferred workholding device on surface grinders. Cylindrical grinding is usually a secondary operation after turning. Often the same center holes used for between-centers turning may be used for grinding the part. As friction is more of a factor in grinding than in other processes, fixture design mustThe size of the holes in the perforated plate determines the fineness of grinding of the particles. Most grains can be ground in a hammer mill. Grain for human food is ground to a 1mm particle size while animal food is ground to a 3mm particle size. Hammer mills cannot be used for wet milling. Roller mills crush the grains rather than millingPOST HARVESTING PROCESSING Food and Agriculture
