Roller Mill Maintenance00

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.

The beam is then rolled to the left until the righthand end is centered over ...

General Use Drive Chains

If the distance between shafts is short, it can be used vertically. The sprocket diameter of a chain drive could be smaller than a belt pulley while transmitting the same torque. Transmitting power by meshing many teeth results in less wear of sprocket teeth than gears. Chain drives have greater shock absorption than gear drives.

OSHA Requirements: Machine Guarding

Rotating parts cause hazards such as inrunning nip points. Parts can rotate closely to each other in opposite directions while their axes are parallel to each other. When they run closely, the stock fed between two rolls produces a nip point. This danger is common on machines with intermeshing gears, rolling mills and calendars.

conveyor belt. If the conveyor belt is undersupported on its return side, the weight of the belt in that section is supported by the pulleys as a catenary load, and greater belt tension is needed to prevent excessive sagging. Belt return support rollers should be spaced so that the belt does not sag excessively between each roller.
