The heating principle of bitumen drum decanter equipment is to heat, melt, and unload the bitumen from the drum using a heating plate. It mainly consists of the drum unloading chamber, lifting system, pusher, and electrical control system.

The bitumen drum unloading equipment chamber is divided into upper and lower chambers. The upper chamber is the bitumen melting chamber, densely packed with heat transfer oil heating coils or hot air heating pipes. The bitumen melts and is removed from the drum. The lifting hook is installed on the gantry, suspending a drum grabber. An electric winch lifts the bitumen drum, then moves it laterally to place it on guide rails. The pusher then pushes the drum into the upper chamber through the two guide rails, while an empty drum is ejected from the rear outlet. An oil-drip trough is installed at the bitumen drum inlet. The bitumen enters the lower chamber and continues to be heated until it reaches approximately 100°C, ready for transport. It is then pumped into an bitumen tank by an bitumen pump. The lower chamber can also be used as an bitumen heating tank.
Bitumen drum unloading equipment is characterized by its adaptability, lack of dependence on the construction environment, and extremely low failure rate. Multiple units can be assembled for high-volume production.
