Operation

Rotary dyers are designed for standard operating pressures up to 10 torr. Constant-speed and variable-speed drives are available in chain-and-sprocket, gear-and-pinion, or direct-drive designs with guards, fan-cooled enclosures, and torque couplings. Dryers can be equipped with self-aligning, anti-friction, pillow block-type bearings and special motor enclosures.

  During operation, the material being dried is mixed by a heated spiral ribbon or paddle agitator. Each agitator is durably constructed with the spiral inner and outer ribbons or paddles welded to support arms on the center shaft. For models RD-2040 and larger, the agitator shaft is heated by a rotary union and siphon pipe. The agitator shaft is sealed by stuffing box assemblies.

  For operating pressures below 10 torr, the shaft can be equipped with double mechanical seals.

Ribbon Agitator

A spiral ribbon agitator can carry material from the center of the rotary dryer to the end plates and back so the batch is constantly exposed to the heated shell and shaft.
