In dry process technology, crushed limestone and raw materials are ground and mixed without addition of water. Dry and semiwet processes are more energyefficient. The wet process requires tons of coal and 110 kWh to produce one ton of cement, while the dry process requires only tons of coal and 100 kWh of energy [4].

Therefore, a roller mill may be a better alternative to a hammermill for swine feed processing [1]. However, roller mills require more vigilance to maintain a gap width that will produce the targeted particle size. Roll gap width will change as rolls wear and grain qualities change. Hammermills will require less monitoring by comparison.

How Does a Cold Rolling Mill Work? The process of cold rolling a metal alloy starts with either sheet metal or strip coil. These materials are placed into large rollers, which compress it down and squeeze it under high pressure just below its ultimate tensile strength. ... The raw material is forced into the die via the compression force. Each ...
