First，the cold aggregate, asphalt and mineral filler are weighed respectively. The batch mix plant process begins when the aggregates is placed in appropriate bins of the aggregate feeders. The aggregates are then transferred to the drying drum by means of a conveyor. Drying drum is equipped with flights internally to promote drying efficiency. Once the aggregates leave the dryer, they are transferred to vibratory screen which does the task of separation of aggregates according to the size and the aggregates are dropped into the separate hot bins.
Asphalt mixing plant, also known as hot mix asphalt plant, it is a very significant machine equipment in road construction. The selection of asphalt mixing plant should be based on the amount of engineering, engineering progress and other requirements to determine the production capacity requirements, and accordingly to select the appropriate model.
Cold Mixing Asphalt Plant . Cold mix asphalt is a combination of mineral aggregate and emulsified or cutback asphalt with additives. Aggregates can be made with virgin materials or reclaimed asphalt pavement, also known as asphalt millings. The latter option is commonly used when trying to save money. Cold mixes can be made on site or at a central location and then transported to the site. The flexibility to create this type of asphalt off-site is particularly useful for remote roads.
The current asphalt mixing plant is mainly hot mix asphalt plant and asphalt drum mix plant,the production and use profile of these two kinds of equipment in the world:
Asphalt concrete mixing plant is critical for construction quality and efficiency in the asphalt pavement. Most of asphalt mixing plants for domestic high grade roads are imported and the capacity is at least 160t/h. With years of experience in asphalt concrete production and construction, we know well that asphalt mixing plant efficiency and concrete quality has direct impact on the failure of asphalt plant and like to provide some information to promote asphalt concrete development and improve high grade asphalt pavement quality.
Asphalt mixing plant is a complete set of equipment used to produce asphalt for road pavement. It is mainly consisting of cold aggregate supply system, drying system, burning system, hot mix elevator, screen, weighing and mixing system, bitumen supply system, dust collection system, hot asphalt storage silo and control system.
Asphalt mixing plant, also known as hot mix asphalt plant, it is a very significant machine equipment in road construction. The selection of asphalt mixing plant should be based on the amount of engineering, engineering progress and other requirements to determine the production capacity requirements.
As special equipment, the standard production of asphalt batching plant is an important tool of process operation, daily maintenance, regular inspection, eliminate accident hidden danger, etc., can effectively ensure the security and stability, prevent wrong operation cause harm to the equipment and produce loss, good maintenance operation also can let the life of asphalt batching plantis greatly increased. Therefore, before every day operation, we should do the proper maintenance of the asphalt mixing station, which will make the asphalt mixing station operate better and create wealth.
To make an asphalt batch mix plant working normally, we have much of work to do, preparation before starting the machine is need, while the correct way of starting the machine is also very important. It is the premise of producing qualified asphalt for pavement construction. Well, if you want to save time and improve the process efficiency, there are 7 aspects we should pay attention to when begin to operate the machine
Asphalt drum mix plant is a complete set of equipment for heating and mixing the asphalt and different particle size aggregates together. It is widely used in high-grade highways, urban roads, airports, docks, parking lots and other engineering construction. Asphalt and aggregates are heated at a certain temperature inside the drying drum according to the design mix ratio to from the qualified asphalt mixture used in asphalt pavement construction. Therefore, asphalt plant is the first key equipment for asphalt pavement construction, and its performance directly affects the quality of asphalt pavement.
