The primary goal for using an asphalt drum mix plant is so HMA (Hot Mix Asphalt) is produced. This mixing plant combines bitumen and aggregates together in order to create the hot mix asphalt. This hot mix is then used as a paving material.
The aggregates that are used can be from one type of material, or they can be a combination of different sizes and types of materials. However, the mixture typically contains aggregates along with filler material from different minerals. This combining of materials helps to create asphalt cement, and this cement can be emulsion, reduced asphalt or produced folios.
What Are The Different Types Of Asphalt Drum Mix Plants?
There are two different types of mixing plants that are used to produce asphalt, and they are Continuous mix plants and Batch mix plants. https://aimix.my/
Although these two mixing plants are totally opposite of each other, they both can serve the same function. The primary difference is the method in which each plant creates asphalt.
What Are The Different Parts Of An Asphalt Mixing Plant?
It is important to know the different parts of this type of mixing plant in order to understand how it operates. In other words, the successful operation of an asphalt mixing plant is dependent on several different components.
It is important that each one of these components is working in order for the plant to be efficient at creating asphalt. So, what are some of the parts that make up an asphalt drum mix plant?

Operating An Asphalt Drum Mix Plant
So, what operations are involved in creating asphalt using this type of mix plant? The very first process that occurs is that the aggregates are fed into feeder containers. The final process of the operation occurs when the asphalt leaves the mixing truck and is pour at the job site.
However, there are several processes that occur within these two that are instrumental in how the asphalt mixing plant operates and how the asphalt is created.
The aggregates are bolstered into several receptacles. These aggregates are unheated, and this the first step of the mixing process. It is important that the aggregates are bolstered according to the different sizes. Cool feeder gates are located on each receptacle, and it is these feeder gates that determine the rate at which the aggregates flow into the receptacles.
After this first step has been completed, the aggregates are transferred to the drying drum. The conveyor moves the aggregates from the receptacles to the drum.
The drying drum is equipped with a burner that heats and then dries the aggregates while they are in the drum.
The majority of these mixing plants also come equipped with another dust collector. This dust collector is used to allow larger dust particles to settle.
The main dust collector works with the secondary dust collector as a filter.
It is vital that each part of an asphalt mixing plant is not only efficient, but that every part is operating as it should. Regular inspection and maintenance will keep this mixing plant running smoothly for continued manufacturing of asphalt for paving projects.
