What are the major components of an Asphalt Mixing Plant? This article provides an overview of the equipment that is used in this process. We will discuss the main equipment of this kind of plant, including the Dryer and Conveyors. We will also talk about the characteristics of the process itself. Lastly, we will discuss the importance of dust collection in an Asphalt Mixing Plant. These machines work to produce a uniform, high-quality asphalt surface.

Equipment used in asphalt mixing plants

Asphalt mixing plants use a variety of equipment to produce finished products. Aggregates are first fed into bins of varying sizes. Each bin is characterized by the particle size of the aggregates. Next, the material is transferred to a drying drum via a conveyor belt. The drying drum typically has flights for efficiency and a secondary dust collector. Finally, the materials are mixed with a liquid bitumen in a specified proportion.

In addition to these mixing arms, asphalt batching plants also feature a mixing tower and elevators. They are compact and highly portable. Their design ensures high efficiency and portability while delivering the same level of mix quality. They are also able to produce up to 140 tonnes of asphalt per hour. The drum mix plant features a continuous manufacturing process, which is more efficient and cost-efficient. The drum plant has a high production capacity and is easy to transport.

Regardless of the number of components in an asphalt plant, it is important to choose one that suits your needs. Modern, mobile asphalt plants are made with international technology and are ideal for small to medium-sized road projects. They feature accurate fabricated dryers, idlers, guide rollers, and steel rollers. They also feature segmented driving sprockets to facilitate smooth and steady movement. The Astec Six Pack plant is the ideal solution for portable asphalt mixing plants.

In September, Systems Equipment Corporation launched a large production version of its ADP-100 asphalt drum mix blend computer. The ADP-100 controls up to 24 feeder channels. It measures liquid mass flow rate and proportions the aggregates as per mix design formulas. New packaging and wiring make the equipment even more versatile. The ADP-100 is one of many innovative solutions for asphalt mixing plants. ADP-100 is also one of the most advanced asphalt mixing plant automation solutions available.

In an HMA plant, the different components are combined and heated at high temperatures to form a finished mixture. Different mixes may also contain additives and mineral fillers. Reclaimed asphalt paving may also be added to the mix. The batching machine also has a cold-feed system that distributes material to a conveyor belt. The conveyor belt moves the materials from the bins onto a gathering conveyer belt. Once the batching is complete, the materials are discharged to the drying chamber.

Process characteristics

There are two main types of asphalt mixing plant: continuous and batch. A continuous asphalt mixing plant produces asphalt mix by mixing liquid asphalt with aggregates in one continuous process. A batch plant requires a continuous flow of aggregates and liquid asphalt to achieve its desired mix proportion. Both continuous and batch types require different levels of equipment. Drum plants can be stationary or portable. They differ in size and are designed to serve one location or a number of locations.

The process characteristics of an asphalt mixing plant can be classified according to how many different components are used in the process. The quality of the mixture depends on the amount of aggregates, sand, and stone dust in the mix. It also needs to be at a certain temperature in order to be durable. If the mixing process is not precise, it can result in uneven, featheredged roads. When a stationary plant is used, the machine will be placed in a location where it is not feasible to move it.

When asphalt is mixed in a plant, the aggregates are screened to ensure a uniform size distribution. Once the aggregates are screened, they are then introduced into a mixing unit in an asphalt mixing plant. The liquid bitumen is then pre-weighed in the heated storage tank and then combined in the correct proportion. The finished product is then dropped into a hot storage silo or truck. These are the two basic types of asphalt mixing plants.

The batch type asphalt mixing plant uses the flame counter-current technique, which has a high level of automation and a small residual water content. Batch mixing plants are more cost-efficient than continuous mixing plants because they do not require the addition of additional aggregates. Continuous-flow plants are more energy-efficient than batch-mixing plants, and are capable of using recycled asphalt as well. In addition to its high-quality output, they are also easier to maintain than batch plants.

Hot mix asphalt is composed of two types: surface course and binder. Surface course consists of aggregates, while the binder course consists of asphalt. A binder course contains larger aggregates and less asphalt than the surface course. During the mixing process, asphalt is chemically modified with polyphosphoric acid. Other materials used in asphalt mixing plant construction are slag, Portland Cement, and stone. In addition to these, coal tar is a black, dark-brown cementitious material that is produced through the destructive distillation of bituminous coal.


A mix plant is a major component of an asphalt plant. It is the device responsible for bringing the different input materials, such as aggregate and bitumen, to a specified temperature and in the right proportion. Conveyors are used to move these materials. Once they are in the mixing plant, they are combined with the bitumen and aggregates, to produce the final product. The mixing plant contains different equipment, such as a mixer, which helps in preparing the bitumen.

Drag slat conveyors transport the hot mix to the silos. Drag slat conveyors are another type of asphalt mixing plant conveyor. These conveyors are equipped with heavy-duty steel casings and are available in several different sizes. These conveyors can transport up to 500 tons of asphalt per hour. Some are also equipped with optional blue-moke recovery systems. These options help in reducing the emission of asphalt.

Crushing and screening plants reduce rocks, stones, and other materials into a suitable form for application. This material is a key ingredient in the creation of roads and pavements, and comprises 90% of an asphalt or concrete mixture. Approximately 28,000 tons of aggregate are used to construct one km of intercity highway, and an average school or house requires 15,000 tons. If you’re planning to invest in an asphalt mixing plant, consider all the options available.

Asphalt mixing plants are usually made at high temperatures, to prevent cooling of the mixture. The mixing plant must also avoid hardening the binder material as the material cools in transportation. Otherwise, the asphalt will harden, compromising the final quality. To ensure consistent compaction and a healthy surface layer, you must invest in a quality mixing plant. If you’re looking for a high-quality mix plant, ALmix offers a variety of models in the 50-600 TPH range.

A major international asphalt mixing plant OEM needed a conveyor system with rugged geared motors and a series of tiered flights inside the dryer drum. These systems are responsible for transferring the hot-dry aggregate to the base of a bucket elevator, which then delivers the finished product up to the raised batching unit. There, the conveyors transfer the dried aggregate to a raised batching unit. With the help of these conveyors, you’ll be able to produce high-quality asphalt in a matter of minutes.


The rotary device is the most critical piece of hot-mix asphalt plant machinery. It must meet exacting specifications, meet the requirements for precision fabrication, and meet application know-how.
