The Directly-heated Drummed Bitumen Decanter asphalt melting equipment is mainly composed of the barrel body, the  barrel platform, the  barrel turning into the barrel integrated device, the heat conducting oil heating system and the electrical control system.
 Top Quality Bitumen Decanter Directly-heated Drummed Asphalt Bitumen Decanting Plant
 
Heating chamber consists of two compartment, upper compartment and lower compartment. There are coiled pipelines which convey heat transfer oil in the upper compartment, hot emission air of diesel burner also exhausts into the upper compartment; heat transfer oil and hot emission air work together to heat the asphalt barrel. When bitumen become melt, it drops down to lower compartment, finally the barrel is emptied. The lower compartment is a melting bitumen pool, beneath it is another compartment which has a lot of coiled heat transfer oil pipelines and a duct for the hot emission air to pass through; the heat transfer oil and hot emission air keep heating the melting bitumen until it becomes liquid; then bitumen pump starts and pump the liquid bitumen to bitumen storage tank through bitumen pipelines. Filtrating device is installed in bitumen pipelines to remove the impurities in the bitumen.
 
Doors on both end of the heating chamber are spring doors that are automatically shut immediately after barrels come through it. Spring doors are easy for barrels coming in and getting out, and able to minimize heat loss as well.
