Drum mix plants are linked to many benefits. If you are thinking about buying a drum mix plant, it is important to know about the different types.
There are 5 drum mix plant types which include the portable asphalt mixing plant, the asphalt soil stabilization plant, and the mobile hot mix plant. The other 2 types include the mobile asphalt plant and the asphalt wet mix plant. Here is what you can expect when you purchase one of these drum mix plants.
The first advantage of drum mix asphalt plants is that the dust emissions are low. The design of these plants also ensures that they are simple to operate. Another advantage is lower fuel consumption, and the control panels are usually fully automatic. Today, the operation of drum mix plants relies on computerized processes to produce asphalt.
Since the process is computerized, it improves the quality of the mixes. Quality control and accuracy are important, especially for the manufacturing companies that are focused on producing high-quality asphalt. With the latest aspal mixing plant, you can rely on modern technology to produce the best products.
Asphalt Drum Mix Process
The process involved with a mini asphalt mixing plant involves feeding aggregates into a feed bin. This equipment usually included 3 to 4 bin feeders (in some cases more) and the aggregates are then loaded into the different bins according to their sizes. The bins also come with adjustable gates that control how the materials flow.
Under the bins is a conveyor belt that transports the aggregates to a scalping screen. The next step of the process includes a screening process. During this step, a vibrating screen is used to remove oversized aggregates, which stops them from getting inside the drum. The charging conveyor not only performs the role of transferring cold aggregates from under the screen into the drum but also weighs the aggregates at the same time. These conveyors come equipped with load cells that weigh the aggregates continuously which sends a signal directly to the control panel.
The mixing and drying drum performs two important operations which include drying first, followed by mixing. The drum rotates continuously, which causes the aggregates to move around the drum. These aggregates are then heat-treated using a burner flame to lower the content of moisture present. The heated aggregates will then be combined with minerals and bitumen.

A pollution control device also plays a vital role in these processes. This device assists with eliminating harmful gases which may be emitted into the surrounding environment. These devices include a dry dust collector known as the primary dust collector that works with the wet dust scrubber or a bag filter, better known as the secondary dust collector.
The load-out conveyor collects the hot mix asphalt under the drum which is then transported to a storage silo or a waiting truck. The storage silos are also used for the hot mix asphalt to store the materials until a truck arrives.
Today, most of the bitumen mixing plant come with sophisticated and modern controls. This allows the operators to control the machine from one place.
