What Is A Bitumen Mixing Plant?

A bitumen mixing plant is one of the most common types of asphalt plants used in the world. One reason for their popularity is that they guarantee quality asphalt mixtures and superb flexibility. The name of bitumen production plant comes from the way the plant produces asphalt.

Batches are produced every 50 seconds, and this time is decided by the mixing specifications of the plant and the capacity of the plant.

How To Operate A Bitumen Mixing Plant?

How to operate a asphalt plant? Generally speaking, aggregates are collected from the piles of stock that is located on the site. They are then placed into cold feeders via a mechanical shovel. Each one of these feeders contains a certain amount of aggregate, and it has a dedicated extractor belt. These days, every plant has a minimum of four feeders. However, more can be installed if necessary. The number needed will depend on how flexible the work is and the specifications of the grading curve.

The transporter belt allows aggregates to feed into the drum for moisture extraction. Heating also occurs in the drum dryer to the correct temperature. The aggregates are then ready to mix and coat with bitumen.

The Importance Of Drum Dryer

The dryer drum is simply a rotating cylinder. It has a series of flights that are located on the inside, and they have the job of lifting the unprocessed materials and then heating them when they come into contact with the air that is produced by the hot burner.

The flame that is inside the dryer of asphalt mixing equipment heats the aggregates by the process of thermal radiation. During this process, elements of combustion and gas are naturally produced in the dryer. They are then passed through a filter before they are given off into the atmosphere.

The Filter

Due to the limits for greenhouse gases and emissions, new technologies have allowed for greater filtering efficiency. This means that problems that were related to the environment have been reduced and simplified.

The materials that are collected in the filter are known collectively as filler. The filler is collected by an auger at the bottom of the filter, and then it is sent by a conveyor belt of the portable asphalt batch plant to the surge hopper. It is at this stage that the filler is weighed again and then fed into the mixer again.

The filter plays a very important role in helping to regulate asphalt adhesion and improve the binding of bitumen to aggregates.

The Mixing Tower

One of the main components of this type of asphalt plant is the mixing tower. It is then transported by a bucket elevator to the re-selecting screen when the aggregates reach a temperature of up to 160 degrees Celsius.

The vibrating screen allows newly separated materials based on the size. After being separated, the aggregates are then fed into the right compartment. They are kept as hot as they possibly can until they are ready to be weighed again.

A bitumen mixing plant offers high flexibility and versatility. They are also ideal for urban construction sites that satisfy a range of production demand.
