In our stationary and mobile asphalt mixing plants all the bins are fitted with individual AC or DC motors and standard make gear box to control and regulate the flow of aggregate from each bin.

The asphalt mix plant can be supplied with a three / four / five / six and even more number of bins.

In our Astech asphalt drum mix plant gathering conveyor is equipped with scrapper and driven by A. C. motor. Aggregate from the gathering is fed to the drum with a slinger conveyor after removing oversize material.

In the stationary as well as mobile drum mixers, a rugged single deck vibratory screen is placed at the end of cold aggregate feeder.

Its job: To remove oversized aggregate material.

In a drum asphalt plant, the conveyor belt is an important component. Driven by an AC motor, aggregates are transferred to drying and mixing unit of the hot mix plant.It is equipped with weigh bridge (Load Cell) for continuous monitoring of weight (tons/hour)

Its job: To weigh aggregate and transfer it to the mixing and drying unit

Drying and Mixing drum:
It is the most important component of an asphalt drum mixer. The rotary cylinder drum is mounted on a sturdy platform driven by A C motor with sprocket and half chain equipped with high pressure jet burner, flights, bitumen and fines piping, frame mounted exhauster fan with high efficiency dust collector fitted with discharge dust screw conveyor. This is the compartment in a stationary or a mobile drum mix where all the mixing and drying of asphalt with bitumen is done at high temperature.

This rotary dryer assures outstanding efficiency in heating and drying the aggregates because of the specially designed and arranged lifting flights. Uniform heating is given to each type of aggregate in the hot mix asphalt plant.

Multi fuel Burner:
In the asphalt equipment, the High pressure jet burner with drying and mixing unit is capable of heating the aggregate to the required temperature without any un-burnt fuel or carbon residue on the aggregate and to reduce the moisture content of the aggregate to minimum. All the stationary and mobile asphalt mix plants come with the unit which is also fitted with suitable type of thermometric instrument at proper places so as to indicate the temperature of exhaust gases, bitumen and mixture. For pressure Jet burner a suitable Fuel storage tank with fuel transfer pump is provided.

The low noise burner has sufficient capacity to cover the entire range of thermal energy required for drying the aggregates with various type of fuel in a portable drum mixer. The combustion of the dryer burner in a mobile hot mix plant satisfies the requirement of environmental regulations.

The stationary or mobile asphalt mixing plant includes a load out conveyor to discharge hot mix material which is approximately 150-180 degree Celsius. The aggregate discharged from the drying drum is collected into an inclined load out conveyor (H. R.) equipped with G. O. B. hopper with hydraulically operated cam shell gates to provide surge capacity when changing trucks and controls segregation in the mix in a stationary or mobile asphalt plant equipment. The belt used in Astech hot mix asphalt plants is a special Heat resistant belt to ensure a long life for your continuous asphalt plant.

In any stationary or mobile drum mixer, there is a provision for addition of dust or mineral to the mix material in the mixing zone of the drying and mixing unit of a stationary or mobile mix plant. It is provided with a rotary valve driven by AC or DC motor. In the stationary or portable drum mixers, filler material is conveyed to the drum through the drum through a pipe by suitable twin lobe compressor.

Storage tanks in our stationary and mobile mix plant are mounted on a sturdy chassis.

The storage tanks in Astech asphalt drum mixer are cylindrical or U shaped. The tank is insulated with glass wool to avoid heat loss and reduce fuel consumption.

Automatic pressure Jet oil burner, bitumen pump with jacketed oil body, bitumen metering system with variable speed motor and hot oil circulation motor is provided as a standard with the main tank.

Depending on the requirement of the customer, supplementary bitumen storage tanks can be provided.

The standard Astech drum mixer comes with a fully computerized cabin with on board electric power console, distribution, switch board and a fully automatic process.

Astech is one asphalt plant manufacturer whose asphalt plant equipment comes with software which is very user friendly and it ensures top notch performance. Display of the entire process control parameters.

Provision to store, edit production details, mix proportions, etc. Auto / manual proportion.

The Control Cabin is fabricated with M. S. Structured frame and insulated by wood.

Strategic location of operator’s seat ensures complete view of the plant.

VENTURI TYPE Wet dust collectors are highly efficient and are known to maintain required environmental standards in stationary or mobile drum mixers. The extreme turbulence leads to superb entrapping of dust laden exhaust gas.

Large size stainless steel nozzle provides a clog free operation to ensure optimum cleaning efficiency.

These pollution control devices can also be fitted on mobile asphalt plants. Bag house filters can also be customized for your stationary and mobile asphalt mixing plants.
