what are the different types of asphalt mixing plants?
Release Time:2023-08-01
With rapid development of the world economy, more and more countries continuously have improved requirements for the grade level of their national roads. Therefore, the quality asphalt mixtures required in road construction are also getting higher. For asphalt plant manufacturers, how to meet the user's customized needs have become more and more popular. To better meet the needs of the users, Sinosun Group has developed a variety of asphalt plants, which can be customized according to the specific engineering projects of the users.

There are many types of asphalt plants available. but what are the different types of asphalt mixing plants? And how to choose the type of asphalt plant ?

There are many factors needing to be taken into account when you endeavor to choose the best asphalt mixing plant, such as your project's properties, your procurement budget, capacity, the model of hot mix plants for sale, etc., each one of which has a huge impact on the final decision so that each one needs to be considered twice.

Usually there are two basic types of plants that are used in the process of making asphalt mixtures: batch plants and drum plants. Let us now take an in-depth look at each type.

The advantages of batch mixing plants:
Batch plants make small accurate “batches” of asphalt mixture through a process that is repeated over and over until the total tonnage for a project has been manufactured.
1. They offer the highest level of flexibility in production.
2. They manufacture a very high-quality finished product due to the accurate measurement of each batch produced.
3. Batch size and production capacity can vary based on the designs of the plants themselves.
4. Due to the intermittent production process, plant operators can easily switch back and forth between different mix recipes if necessary.
The advantages of drum mixing plants:
Drum plants, on the other hand, prepare the asphalt mix through a continuous process and require the use of silos for temporary storage prior to the mix being trucked to the paving location.
1. There is no interruption in the production process as there is a continuous flow of aggregate and liquid asphalt into the drying/mixing chamber.
2. There are several different configurations of drum plants, all depending on how the aggregate flows in relation to the hot air, which is responsible for heating and drying the materials.
3.In parallel flow, the aggregate and air flow in the same direction through the chamber.
4.In counter-flow plants, the aggregate and air flow in opposite directions through the chamber.
5.In double drum or double barrel plants, there is an outer shell through which the aggregate flows before coming in contact with the hot air inside the chamber.
6.Regardless of the configuration, it is a continuous process that creates a homogeneous mixture that can be manufactured at a high rate (sometimes as high as 600-800 tons per hour).

In addition, to choose an asphalt mixing plant it is necessary to understand each type, their characteristics, advantages and disadvantages, configuration and other details in order to choose one as per your construction requirements.
1) Based on Production Capacity
The Small and medium-sized asphalt plants are usually used for small construction projects. These include asphalt mixing plants with capacities from 20 TPH to 100 TPH. They are used in road construction, parking lots, etc.
2) Based on the ability to move
The Stationary Asphalt Plant, as the name suggests cannot move around during the construction process. Therefore, the asphalt mixture that is produced has to be transported to the required location.
3) Based on the Technical Process
The continuous asphalt drum mix plants are capable of producing asphalt mixture steadily without any interruptions. They can integrate the drying and asphalt mixing process together at relatively lower cost. It is why the continuous asphalt plants are favored in large construction sites.
The asphalt batch mix plants are widely used for construction projects. It can produce the highest quality of asphalt mixture. It is best suited for those projects which require the specifications of the mixture to be changed during the process.

If you are looking for asphalt mixing plant, regardless of the type and size, Sinosun Group can help you, and can meet all the needs of customers. For any queries regarding asphalt mix plants, please feel free to get in touch with us.
