込んで廃材貯蔵ビンに貯蔵する。Function: In the asphalt plant of the present invention, new aggregate and waste material are heated separately in drums. When heating waste materials in a drum, the waste materials are fed into the drum and hot air is sent in by a burner in the same direction as the moving direction of the waste materials to heat the waste materials using a co-current heating method. Then, a part of the cooled exhaust gas that is led out from the drum to the exhaust flue is sucked up by an exhaust fan installed in the exhaust gas circulation piping, and guided into the combustion chamber of the burner to lower the temperature of the hot air sent into the drum. This prevents the waste material from being extremely heated. The heated waste material is lifted to the upper part of the plant via the hot elevator, and by switching the damper for changing the route of the discharge chute of the hot elevator, it is dropped into the branch chute and stored in the waste material storage bin.

。When heating new aggregate, the exhaust fan installed in the exhaust gas circulation pipe connected to the drum's exhaust flue is stopped, and high-temperature hot air flows into the drum without circulating the exhaust gas into the combustion chamber of the burner. Feed the new aggregate and heat it using the parallel current heating method. The heated new aggregate is stored in aggregate storage bins in the plant main body via a hot elevator according to particle size.

するのである。Based on the formulation of the asphalt mixture to be manufactured, aggregates of various particle sizes are weighed in an aggregate measuring tank and fed into the mixer, and if necessary, waste materials to be stored in a waste storage bin are placed in a waste material measuring tank. The amount is measured and put into a mixer, and then asphalt and stone powder are added to produce an asphalt mixture.
