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 supplied into the drum and hot air is sent by a burner in the same direction as the moving direction of the waste materials to heat the waste materials in a co-current heating method. 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 to the combustion chamber of the burner, where the temperature of the hot air sent into the drum is adjusted. The temperature is lowered to prevent the waste material from being excessively 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.

本体の骨材貯蔵ビンに粒径別に貯蔵される。 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, sorted by particle size.

る。 Based on the composition of the asphalt mixture to be manufactured, aggregates of various particle sizes are weighed in an aggregate measuring tank and fed into the mixer.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 asphalt and stone powder are added to produce an asphalt mixture.
