Dry drag chain conveyors can be applied to precipitators, fabric filters, boiler hoppers or cyclones for the collection of fly ash. These units handle fly ash in a dust-tight, air-tight construction which provides dust and fire control.

The drag chain conveyors can move materials at very low speeds to a storage and/or disposal location, and can have up to a 35 degree incline. These conveyors occupy minimum space with maximum materials handling capabilities.

The drag chain conveyors can withstand higher temperatures and have a dust-tight casing of steel. In addition to the outlet at the drive station, the conveyor can be fitted with hydraulically-operated slide gates at points along the casing. The design of the chain links in drag chain conveyors ensures optimum strength.
