The aggregate is supplied by the elevator to the rotary drying drum that removes moisture, and then it is sieved into several groups according to the particle size and stored in the "hot aggregate bin". After weighing, it is sent to the mixing tank and mixed with the powder and hot asphalt.
The working cycle of one batch is about 45s.A hot mix asphalt plant with a mixing tank capacity of 1500 kg can produce 120 t/h.
Its advantage lies in the high quality of the finished asphalt mixture and no waste of aggregate. Another advantage is that it can switch the specifications of the mixture as needed.
Asphalt drum plant
The continuous asphalt plant is known as the asphalt drum plant. The first two-thirds of the drying drum is dedicated to dehumidification. In the last third of the unit, inject the correct percentage of asphalt and mix all the materials thoroughly.
The advantage of the asphalt drum plant is to reduce the hot mixing process to the most basic requirements. By eliminating most of the asphalt mixing steps, it can complete its work more economically.
Since the mixing process is continuous, they will also run at higher production rates depending on the drum size. However, according to its structure and workflow, only one hybrid design can be produced at a time.
According to the mode of transportation, the hot mix asphalt plant can be divided into mobile asphalt plant for sale and stationary asphalt plant. It is easy to make choice. You just need to think about the two questions: Do you need to move your asphalt mix plant? If so, how often will it move? If you only need to move your equipment once every few years, a stationary asphalt plant will be a better choice.
