Introducing the mechanism and operation of the hot asphalt plant
This machine consists of several devices that use raw materials including gravel, bitumen, filler and if needed for other additives, produce the required asphalt.
At the first, 4 or 6 types of sand and grains are loaded into the cold material silo, then poured onto the transfer belts by tape feeders that can be controlled from the control room in certain proportions that enter to the dryer which is responsible for drying With the circulation of the dryer and high heat, the raw materials are dried and its moisture evaporates, and after drying, the micron particles are separated from the aggregates and sucked by the exhaust fan. They are deposited inside a device called a cyclone using a centrifugal mechanism, and then these deposited materials are transferred to the filler alluvium by screw feeders and transferred to the top of the tower for storage. Also, the materials that have reached temperature of 140-180 degrees Celsius are transferred to the material elevator and are transferred to the upper floor of the tower, which is sieving machine, and separates the material sieve and keeps it in 4 to 6 tanks.
Bitumen is another additive that after storage in bitumen flask and heating by oil heater is kept at temperature of 110 to 140 degrees and when needed, it is weighed by the operator with an automatic system and added inside the mixer.
This mixture can be prepared depending on weather and environmental conditions with different mixing conditions by adding other additives such as cement, acid and pigments, etc. This part is made and prepared as an option according to customer requests.
After mixing completely, the asphalt mixture is stored in another section called asphalt storage silo.
Asphalt plants in capacities of 60-80-120-160 tons are produced in Komaco design in this company.
Screen of Asphalt plant is specifically designed with a coating to prevent dust extraction as well as resistance to abrasion. Mixers of asphalt based on tonnage final sintering plant Asphalt 5, 6, or 7 rows of tiles resistant and interchangeable, the body of the mixer does not harm. To thicken the asphalt and better quality, the dust stacked on drying and sieving, once again in the mixer in proper proportion to the mix is added. Emulsion is used to make asphalt instead of asphalt
