EAGER series asphalt concrete hotbox is a professional asphalt concrete heat insulation equipment. The equipment can heat and preserve mixed asphalt mixing materials, with good re-heating and insulation function. Heating through the heat transfer oil, can avoid local high temperature(The heating method of thermal conductive oil can avoid the local overheating caused aging),constant temperature control to ensure the heating not coke and not condensing for the use of asphalt aggregate process. (thermostatic control system to ensure the heating and the use of asphalt aggregate process is not coke, not condensing;) Hydraulic control asphalt concrete discharge, with force, stable, low noise, adjustable speed advantage; at the same time it can also discharge artificially through the discharge door.
