Asphalt plants are used to produce hot mix asphalt. It mixes aggregate and asphalt to make hot mix paving materials. Aggregate here can be a single size material or a mix of various grades/sizes of material. The asphalt mixing plant is mainly composed of cold aggregate supply system, drum dryer, burner, coal feeder, dust collector, hot aggregate hoist, vibrating screen, filler supply system, weighing and mixing system, asphalt storage, asphalt supply system etc.

Asphalt mixing plants are generally divided into batch plants, which produce a series of batches of asphalt, and continuous plants, which produce a continuous flow of asphalt (these are usually of the drum mix type). This classification not only reflects production methods, but also highlights different quality control needs. Equipment may be used and/or modified to meet the demand for asphalt mix production using recycled bitumen. A variety of batch mixing equipment has been developed to meet project needs. PRIMACH has different types of asphalt batch plants available, covering a wide range of applications, below is an introduction to our most popular asphalt mixing plants.

In this type of plant, bitumen is produced in batches every 40-50 seconds, depending on the capacity of the plant and the mix specification. New continuous drum mixing plants with counter-flow technology are setting new standards for asphalt mix production in the 80-160 t/h production class. The main advantages of the plant are fuel efficiency, low carbon footprint, environmental protection and the facility to add RAP.

At the heart of the unit is a high-efficiency counter-flow drying tumbler with matching fully adjustable proboscis burners. In traditional continuous mixing equipment, parallel heat transfer technology is used where the material to be heated and the hot gas flow parallel to each other in the same direction. In a counter-flow dryer drum, the material to be heated and the hot gas flow opposite each other, i.e. in opposite directions. This is an efficient heat transfer system that maximizes heat transfer from the hot gases and radiant heat from the burner flame to the aggregate. Spraying of bitumen and filler is done as the hot aggregate passes after the burners in the same drying drum.

Our PM Series batch asphalt mixing plant has a complete product lineup, including stationary, mobile asphalt batch mixing plants and continuous drum mixing plants. Thanks to its compact design, it can fit into some small spaces with full functionality. Precise control system, quick response initiative and stable quality can satisfy almost all customers' needs in a more economical way. At present, our intermittent asphalt mixing plant has been put into use in Libya, Thailand, Peru and other countries. It is not only an ideal choice for highway construction, but also an ideal choice for other highway maintenance tasks. As one of the leading manufacturers and total solution providers in the asphalt mixing equipment industry, PRIMACH is also able to provide customized services according to the actual needs of customers. Meet different construction needs.
