Structure of Drying Drum System of Asphalt Mixing Plant The drying system is one of the main components of the asphalt mixing equipment. Its main function is to heat and dry the aggregates and heat them to the temperature required to obtain high-quality asphalt mixture.

Counter-flow plants can feature a single drum for drying and mixing or two drums (separate for drying and mixing) or drum for heating and a mixer for mixing. Usually drum plants are smaller than the asphalt batch plant and require less space, less energy and less efforts to run. The components are also less in the drum asphalt plants

asphalt (asphalt cement) and air-blown asphalt (oxidized asphalt). Straight-run asphalt is used for paving roads, airport runways, and parking lots. Because of its solid to semi-solid nature, it must first be cut with a solvent to bring it to a more liquid state. This is known as cut-back asphalt. Highway workers are most likely to use straight

Continuous (Drum) Plant Operations In the production of asphalt by drum mixing, aggregate gradation is controlled at the cold feed and therefore ensuring the cold feed's accuracy is essential. Installing Hydronix Hydro-Probe moisture sensors at the belt weighers or at the base of the cold feed bins allows

These are continuous (drum-mix) and batch type plants. As understood from their names, they differ from each other by their production methods. In continuous types; asphalt concrete produced

There are two basic types of asphalt plants, the batch process plant and the drum-mix plant. In the batch process, aggregate is typically dried by the application of heat to the aggregate as it passes through a drum rotating on an inclined axis. The hot, dry aggregate is then transferred to a pug mill, in which it is mixed with asphaltic cement.

Asphalt batch 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.

In a general manner, a concrete batching plant is mainly made up of aggregates supplying system, batching system, mixing system, discharging system and controlling system. On the base of aggregate lifting times, concrete batching equipment can be classified as concrete batching building and concrete batching station.
