Alltech Asphalt Batch Mix Plant

The perfect balance of powerful, low installation cost and easy movable asphalt mixing plants was developed by Alltech Research& Design team.  Alltech plants are skid mounted so it saves RCC foundation work cost.

Each new technology proudly presented by Alltech is a value for the world in the name of Energy saving & environment. In addition to our efficient products in asphalt technology, short reaction times, excellent development competence & state-of-the-art production facilities characterize our company.

Asphalt – Production Process

Four Been Feeder

At an asphalt mixing plant, the aggregate material is stockpiled according to grain size and type. This material is usually loaded into the individual hoppers by a wheel loader. The minerals are dispensed via dosing belts (normally frequency-controlled) onto the collecting belt below, specific to the recipe. In this way, a corresponding cold feed recipe is generated on the collecting belt. The material is then transported to the dryer drum via this collecting belt.

Dryer drum

The dryer drum is known as a rotary dryer. Here, the material is dried and heated for further processing. For the manufacture of asphalt, it is essential to remove the moisture from the base material to ensure bonding with the bitumen. Designed at an appropriate inclination, it transports the material through the entire drum via rotary movements. Lifter plates in the drum provide a thick material curtain in the drum, enabling efficient heat exchange. In addition to the dusts produced, water vapour is also generated during this drying or heating of the aggregate. In order to keep heat losses to a minimum during the drying process, the drum tube is insulated against heat radiation.

Burner

The burner used for drying and heating can be operated with fuel oil, fat oil, natural gas, fluid gas, carbon dust or a combination of these combustibles. During operation, the operator can change the combustible with the help of his controls. Alltech is the only manufacturer of asphalt mixing machines worldwide developing and manufacturing its own burners. Here you can learn more about our combustion technology.
