Roller Mills. Roller milling is a process used to separate the parts of grain and then grind into flour. The rollers rotate at different speeds and the material is sheared as it passes through the gap. Some flour mill machines use a belt with synchronous on one side and vribbed on the other. Other machines require a belt that is vribbed or ...

Also known as ring rollers, these curvers shape wire, rods, and flat stock into curves and circles. Turn the handle to drive material through the steel rollers. With each pass through the rollers, tighten the tensioner knob in small increments to gradually increase the curve.. Curvers with stand come with three sets of rollers— one for flat stock and two for wire and rods.

The construction of a triple roller mill is shown in Figure. It consists of three parallel rollers of equal diameters. These are made up of hard abrasionresistant material, normally stainless steel. The rollers are mounted in a rigid framework horizontally. The pressure and gap between the rollers are independently adjustable.

Unlike a hammer mill, a roller mill doesn't require an air assist system to pull material through the filtering screens. With hammer milling, a lot of extra electricity is needed to help pull that material through. That electricity usage translates into increased energy costs. 3.
