Roll Size. The first step in producing a compact roller mill would be to reduce the size of the rolls. However, there are two major constraints on the size of the roll: Firstly, the diameter is constrained, because of the way the coffee beans enter the roll. "You need a certain angle [between the rolls] called the feed angle, that limits how ...

ABSTRACT. The comminution or size reduction process is an important unit operation in the process industries in which solid materials are broken or cut into smaller sizes by the application of mechanical stress. Solids can be reduced in size by crushers and grinders which employ compression, impact, attrition, shear, or combinations thereof.
