Powder metallurgy – basics appliions
The grinding media may be made of hardened steel, or tungsten carbide, ceramics like agate, porcelain, alumina, zirconia. During rolling of vessel, the grinding media powder particles roll from some height. This process grinds the powder materials by impact/collision attrition. • Milling can be dry milling or wet milling.

The history and processes of milling
· The friction between the stones heats the flour up gradually preventing the loss of the enzymes and the vitamins in the flour without compromising the baking quality. The grain is ground once and then sifted to remove large parts of leftover grain. These pieces can be milled once again to even out the size of the flour.

How ball bearing is made
The bulge around the middle of the rolling balls is removed in a machining proess. The balls are placed in rough grooves between two cast iron discs. One disc rotates while the other one is stationary; the friction removes the flash. From here, the balls are heat treated, ground, and lapped, which leaves the balls with a very smooth finish.

The history and processes of milling
· In the late 18th century, Oliver Evans invented the first automated flour mill in the United States that did the work of seven men (Basey 7). It used millstones, had an enormous amount of levers and pulleys, and was very noisy. Evans' mills were water powered, so they were situated along rivers.

How ball bearing is made
5 The first machining process removes this flash. The ball bearings are put between the faces of two cast iron disks, where they ride in grooves. The inside of the grooves are rough, which tears the flash off of the balls. One wheel rotates, while the other one stays still.

Pulverizer
As the lower ring rotates, the balls to orbit between the upper and lower rings, and balls roll over the bed of coal on the lower ring. The pulverized material is carried out of the mill by the flow of air moving through it. The size of the pulverized particles released from the grinding section of the mill is determined by a classifier separator.
