The drive assembly is the component that causes a rotary kiln to rotate. While a variety of drive assembly arrangements are available, the selection of one type over the other is dependent on the drive horsepower and the size of the kiln.
FEECO offers the following drive assemblies:
Chain and Sprocket: ideal for small kilns running up to 75 horsepower. A large sprocket wrapped around the drum has a chain on it that goes to the reducer and motor. The motor turns the gear box, which spins a small sprocket attached by a chain to the large sprocket.
Gear and Pinion Drive: reserved for applications running over 75 horsepower. The gear drive operates and wears better in demanding, heavy-duty applications. Here, a gear wrapped around the kiln meshes with a small gear drive and causes the drum to rotate.
Friction Drive: best for small applications with low horsepower. This is normally used with kilns approximately 6’ and under. With this assembly, two of the four trunnion wheels are connected by one shaft and driven by a shaft mounted reducer and motor arrangement.
Direct Drive assemblies are also available, and are best used for small to medium sized drums running up to 75 horsepower.
FEECO’s kiln experts are well-versed in rotary kiln sizing and design, and they look forward to determining the drive assembly best for your needs.
