Asphalt Mixing Plant: Road Constructions Equipment

Asphalt concrete is a composite material used for construction of road. Equipment we used for manufacturing of asphalt, macadam and other form of road stone is called Asphalt mixing plant. Road stone are manufacture by mixing number of aggregates, sand and a filler like stone dust. These all aggregates are mixed in a correct proportion and temperature. Mixing of asphalt and aggregate is done in one of several ways. Many types of equipment are needed for road developing. All these equipments are from the best quality. Asphalt mixing.org is one of the trusted names for developing Asphalt mixing plant equipments.

Asphalt mixing plant has several classes of plant like: Asphalt drums mix plant, Asphalt wet mix plant, Asphalt batch mix plant, Asphalt hot mix plant. In the Asphalt drum mix plant, raw aggregate is brought up from ground hoppers at a precisely controlled rate and fed into a heater drum. After heating it is immediately coated in the same drum with the use of binder spray bars situated behind the burner or in a smaller drum situated behind it. Complete product is almost always discharged into a hot store not directly into delivery vehicles. Changing mix is achieved by varying the feed rates of the aggregate, stone dust and binder feeders, with time delays so that the change of blend occurs at the same point in the coating drum. Sand tends to move more slowly through the heating drum, so the blend proportions will not necessarily change at the same point on the feed conveyor. It is common to divert a small amount of material to a waste chute when the transition point reaches the hot elevator. In this way Asphalt drum mix plant work. Drum mix plants are not really suitable for short production runs. It comes in various TPH.

Asphalt batch mix plant is another class of Asphalt mixing. It weighs the raw aggregates into a heater drum, where the batch is then heated up to temperature. The hot aggregate is discharged into a mixing drum where (dry) filler and binder are added. The blend is mixed and discharged either directly into the delivery vehicles or into a small weighing and collecting hopper. To increase throughput, the heater can be heating the next batch while the previous is being mixed. Capacity is usually of the order of tens of tones per hour. Best products are for developing roads.
