Asphalt batching plant manufacturer hot mix in batches. Small Asphalt plant process are mix of several mechanical. Electrical components that help make HMA. This equipment can be mobile or stationary. Other types of plant that are available in the market today. It is drum mix plant and counter flow plants. But in general the major categories are batch plant and continuous plants.
Including aggregate and drying drying in the process of asphalt batch plant. Each combines in different parts and then mixes it into a twin shaft mixer. With bitumen and filler material. Drum Mixing Plant Aggregates are heated and mixed with bitumen and filler material in a continuous process. Although both processes help to make a Hot mixing asphalt. There is a difference in this process.
Advantages of Asphalt batching plant:
Atlas is supplier of Asphalt batching Plant in Nigeria and Philippines. below describe some advantages of asphalt mix plant. Available here 60 tph to 180 tph small to big asphalt plants.
- Most accurate equipment to make hot mix asphalt.
- It is possible to easily incorporate recycled asphalt in the mix.
- It is possible to control the production and quality of the end product.
- Components are make a batch weighed individually before the mixing process.
- This plant helps to work with many clients as recipes. It can be changed easily without compromising on the quality.

Asphalt Batch plant components:
In a Asphalt batching plant aggregates are heated, weighed. Most Important Components of mixed with the bitumen and filler material. In certain cases when there is a need to use recycled material. RAP is weighed separately and then mixed with the weighed aggregates in the mixing unit.
Basic components are as:
- Feeding unit
- Primary screen and charging conveyor
- Drying drum with burner
- Primary and secondary pollution control devices
- Vibrating screen
- Hot bins
- Mixing unit
- Bitumen tanks
- Hot oil heater
- Filler addition silo / hopper
- RAP feeder
- Storage silo
- Control panel
Process of Asphalt Mix Plants:
The feeder bins store different sizes of virgin aggregates in separate compartments. The aggregates are then transferred to the drying drum by the help of a conveyor. There is a primary vibrating screen for screening over sized material. Inside the drum and the virgin aggregates will undergo heating and drying process. There is a burner which helps in drying and heating the aggregates. Material enters on the opposite side of the burner and travels. The entire drum length to come out from the burners. End to be transferred to the vibrating screen on top of the tower unit. Since the entry of aggregates and burner flame is opposite to each other. This process is called as counter-flow process.
Atlas is one of the reputed asphalt batching plant manufacturers from India. who focuses more on quality rather than quantity. The tower unit of the machine consists of multiple deck vibrating screen on the top followed by hot bins. Below the hot bins is the mixing unit. As the material enters the vibrating screen. They are screened and separated in different compartments as per their size. These storage compartments are known as hot bins.
A required recipe is set in the control panel and weighing. Aggregates are done at the hot bins. So that the required amount of aggregates are added. Each bin has individual scales which ensure that the correct proportion. Each aggregate is weighed and mixed. This ensures that the batching plant is most accurate. Delivers the exact material.
At the same time, bitumen and filler material is weighed and added in the mixer. Mixing time is controlled by the control system. After the homogeneous mixing. The hot mix asphalt is transferred to storage silos or directly unloaded into waiting trucks.
There are storage tanks for bitumen and storage facility for filler material. Dry dust collector will help trap heavy dust particles. The finer dust will be trapped by the bag filters. Bag houses are known to be the best pollution control devices for asphalt plant.
The amount of material that the mixer makes in a specific time till it opens. Its gate for unloading is called as a batch. The total capacity of batches in an hour will determine the production capacity of the equipment.
