Product Description
sphalt drum mix plant is also generally known as continuous mixing asphalt plant because it can produce asphalt mixture continuously instead of in batches like forced mix asphalt plant. Asphalt drum mix plant can be divided into stationary type and mobile type. According to our years of sales experience, if a customer chooses a drum mix asphalt plant, he will choose the mobile type in most cases.
Asphalt drum mix plant is generally used in the construction of township roads. Because it is very flexible, you can move it to the next construction site very quickly when one project is finished.
On Asphalt Drum Mix Plant, aggregate are continuously dried and mixed with bitumen during production, thus, it is also called continuous asphalt plant.

Components and Features
An asphalt drum mix plant consists of the cold aggregate feeding system, bitumen supply system, burner, drying drum, finished asphalt elevator, finished asphalt silo, water dust collector and control system. In the case of mobile asphalt drum mix plants, the components include an additional travel system.
Cold aggregate feeding system: Cold material generally refers to different sizes of aggregates. Customers can choose 3 or 4 cold material storage hoppers.
Bitumen supply system: The continuous asphalt plant uses a direct heat asphalt tank to heat the bitumen.
Burner: We have diesel burners, coal burners and gas burners to choose from.
Drying drum: It has the function of drying and mixing. Dry the aggregate entering the drum, at the same time, the drum rotates to complete the mixing of aggregate and asphalt.
Finished asphalt elevator: Lift the finished asphalt through the elevator to the finished asphalt silo.
Finished asphalt silo: Store the finished asphalt mixtures and unload it into a dump truck. Then the dump truck transports the finished asphalt to the construction site.
Water dust collector: Collecting dust generated during the production process.
Control system: It contains control room, operation desk, control cabinet, air conditioner, etc. It can realize semi-automatic control of the whole asphalt plant.
Working Principle
The asphalt drum mix plant process is relatively simple, which can be broadly divided into four major parts: batching, heating, mixing and storage.
Batching: The raw material of asphalt drum mix plant is mainly aggregate and bitumen. Aggregates are weighed in the batching machine, while bitumen is mainly controlled by adjusting the flow rate of the asphalt pump to control the percentage of bitumen.
Heating&Mixing: The weighed aggregate and bitumen are fed into the drying drum at the same time. After being dried and heated, the aggregate is mixed with the bitumen to complete the mixing process.
Storage: The finished asphalt mixtures will be fed into the asphalt storage hopper by the bucket elevator and then transported to the construction site by the dump truck.
Application:
Asphalt drum mix plant is mainly applied to produce HMA (hot mix asphalt) or asphalt concrete for small and medium sized road pavement and rehabilitation.
