· Bed Mill: A bed mill, on the other hand, moves the material perpendicular to the bed of the mill moves along the Y and Z axes and the spindle moves along the Xaxis, providing a full, 3axis range of movement. The spindle movement, coupled together with the horizontal movement of the table enables milling of a variety of depths and shapes.
Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill "sees" instantaneously unless some damping system such as a surge hopper is used.
