FEECO offers a variety of options in drive assemblies for your rotary dryer, cooler, kiln, or granulation drum, all selected based on the requirements of the application.
Chain and Sprocket Drive Assembly
Chain and sprocket drive assemblies are ideal for smaller drums running up to 75 horsepower.
How it works: A large sprocket, wrapped around a rotary drum, has a chain on it that goes to the reducer and motor. The motor turns the gear box, which in turn, spins a small sprocket attached by a chain to the large sprocket.
Gear and Pinion Drive Assembly
The gear and pinion drive assembly is ideal for heavy-duty applications running over 75 horsepower. This assembly is more costly, but it operates and wears better in demanding applications.
How it works: A gear wrapped around the drum meshes with a small gear drive, which causes the drum to rotate.
Friction Drive Assembly
The friction drive assembly is best for small applications with low horsepower, often seen with drums 6’ or less.
How it works: Two trunnion wheels are connected by one shaft and are driven by a shaft mounted reducer and motor arrangement.
Direct Drive Assembly
A direct drive assembly is ideal for small to medium sized drums running up to 75 horsepower.
How it works: A shaft is mounted to a solid discharge end plate at the outlet of the drum. The motor and reducer are directly connected to this shaft with a coupling, or with a shaft mount arrangement.
Overall, drive assemblies are chosen based on the size and horsepower needs of the drum. To learn more, contact us today!
