Water wheels were available for hoisting materials and for crushing ores. There were mills for making beer, olive oil, poppy oil, mustard, coins, and wire. Water wheels were used in the preparation of pigment, paper, hemp, and tanning bark, and for fulling, sawing wood, boring pipes, and ventilating mines.

Horizontal In-Feed Hammer Mills The unique quality of the horizontal in feed mills is that material is fed into the side of the hammer mill, instead of the top. This design makes them ideal for long, linear or otherwise large, geometric materials to be processed without a pre-grind. This group includes trim scrap grinders

the screen in the hammer mill determines the size of the output product. Also, Koch (2002) added that hammer-tip speed, hammer design and spacing, and the use of air-assist such as suction fan and cyclone separator affect the size output of the hammer mill.
