The basic functions of grinding fluids are very similar to those of other cutting fluids despite large differences between the dynamics of the process. "In machining we tend to think that softer materials will benefit from higher lubricity and harder materials will require higher cooling capabilities. The same is true for grinding," said Foster.

Although there are two methods of doing a grinding operation, one is wet grinding and the second one is dry grinding. Wet grinding: In wet grinding, during the grinding operation, we sprayed coolant generally water or any coolant to cool the surface so that the longevity of the grinding wheel increases and also we get a fine surface finish.

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Thus dry grinding can be less costly. A closed circuit dry grinding system is very space consuming because of the classifier, the transport devices, the dedusting filter, etc. The feed to a dry grinding system must be dried if the moisture content is high. A ball mill is more sensitive to clogging than a rod mill. An air stream through the mill ...

When a sample is dry ashed, a fine residue (ash) is often formed. The small particles in the residue are resuspended readily by any air flow over the sample. Air flows are generated by changes in temperature (e.g., opening the furnace while it is hot) or by passing a stream of gas over the sample during heating to assist in combustion.

During the grinding process it is common to use a coarse grind to initially promote uniform distribution of fat followed by a second or final grind. The final grinding step will often call for a finer grind, say 1/8 inch for the lean meat with a 3/16 inch grind for the fatter meats. This system likewise reduces the possibility of smearing.

Dry milling is often used to describe three different processes when talking of maize. The first process, stone grinding, is the oldest and is also known as whole kernel dry milling or full fat dry milling. Whole kernel dry milling does not seek to fractionate the maize kernel but to grind it into uniform size particles, usually flour or meal.
