I am interested in grinding wheel technology for food grinding application. The targeted materials to be grind are spices, cereal grains, pulses and other similar stuff. The grinding wheel should
Silicon carbide is an abrasive used for grinding gray iron, chilled iron, brass, soft bronze and aluminum, as well as stone, rubber and other non-ferrous materials. Ceramic aluminum oxide is the newest major development in abrasives.
Natural diamonds can be used for grinding very hard materials (like granite, stone, cemented carbides, marble), but have almost completely been squeezed out of the market by synthetic diamond wheels, due to the low cost of the latter. Manufactured diamonds are used for grinding aluminum oxide cutting tools, very hard steels and cemented carbide.
Blue wheels are harder and are good for sharpening drill bits and lathe tools. Grey wheels are softer, and work fine. Waterstone wheels are made of synthetic waterstone material and are fairly soft but excel for sharpening knife blades. The two biggest things are: A good water film on the wheel. The water should be clean and non-acidic.
Resin wheels are made much like a traditional grinding wheel with a thick bond/grit layer usually between 1/16" and 1/4". Electroplated wheels are a much thinner thickness. In both cases, the bond layer is applied to a hub which is either aluminum or steel made to the specific profile required.
In the form of bonded wheels, natural diamonds are used for grinding very hard materials such as cemented carbides, marble, granite and stone. Recent developments in the production of manufactured diamonds have brought their cost down and led to expanded use.
A grinding wheel is a wheel composed of an abrasive compound and used for various grinding (abrasive cutting) and abrasive machining operations. Such wheels are used in grinding machines . The wheels are generally made from a composite material consisting of coarse-particle aggregate pressed and bonded together by a cementing matrix (called the
The basic component materials of grinding wheels are abrasive mineral grains and bonding material. The abrasive mineral or synthetic mineral grains must be selected with respect to material that
