When it comes to buying an asphalt plant, you need to decide what is the best configuration and layout, as well as the best system for your requirements. There are two main different types of plants: continuous and batch. In this short article, we are going to be talking about some of the features, benefits, and common applications of continuous asphalt mixing plants and batch asphalt mixing plants. The truth is, however, that there is no ideal solution, as every business needs to carry out its own production analysis to determine which system and layout are optimal for its needs.
Continuous Plants
In a continuous asphalt mixing plant, the production cycle is uninterrupted and can operate 24/7. The mixing process is carried out in the dryer drum, as raw materials are dried and mixed simultaneously. Since there is no need for any elevators or mixing towers, a continuous plant has a much more simplified design than a batch plant and subsequently has lower maintenance costs. However, the absence of a screen means precise controls are necessary at the start of the production cycle. This type of plant is preferred by producers who need large quantities of one formulation of an asphalt mix.
Continuous plants usually have volumetric metering systems for filler, which use variable-speed feed screws. Some of the older models, however, have pneumatic metering systems. The bitumen and aggregates also metered volumetrically.
Batch Plants
The asphalt batch plant is the most common type of plant in operation across the world because it offers flexible production and asphalt mix quality. A new batch of asphalt formula can be produced every 50 seconds. However, all the raw materials for the mix needed to be weighted separately first. The reason this plant is so popular with producers is that it allows them to easily alter the mix specifications for asphalt production for different clients without sacrificing quality or speed of production.
In batch plants, the filler is measured by weight in a hopper and fed into the mixer by gravity. However, some models have screw conveyors to feed the filler into the mixer. The bitumen is also metered by weight, while aggregates are initially metered by volume.
Asphalt Mixing Plant Suppliers
Most asphalt mixing plant suppliers stock both types of plants and can also offer custom plant configurations to customers. It’s important to pay attention to the technical specification when comparing mixing plants from different suppliers. Furthermore, it’s best to order your components from a reputable manufacturer who is a known global brand. That way, you can rest assured that you are buying a quality product.

Conclusion
So what type of plant is better the continuous asphalt mixing plant or the batch mix asphalt plant? Well, it depends on the application. Batch plants are best for producers who serve multiple clients and want production flexibility and the ability to make special formulas as required. Meanwhile, continuous plants are best for producers who want low operational costs, 24/7 mass-scale continual production, and high-consistency end product.
