Asphalt drum mixers are indispensable tools which are commonly employed in road construction works to manufacture continuous and uniform asphalt mixtures. Drum mixers are single continuous processes unlike batch-type plants where drying and mixing occur in the same drum. The design also makes them very efficient, economical and suitable in long term or large scale asphalt paving works. Drum mixers have proven themselves as the choice of contractors in the world due to their capability to provide continuous production with a lot of minimum interruptions.
The asphalt drum mixer is made up of various major parts among them being aggregate feeders, a drying and mixing drum, a high-performance burner, fuel systems, mineral filler units, bitumen tanks, and a control panel. The aggregates are introduced into the drum, then they are heated, dried and completely combined with liquid bitumen to form a homogenous mixture of asphalt. This equipment is continuous and therefore guarantees consistency in production and quality and fewer complications in operations.
High production efficiency is one of the best strengths of asphalt drum mixers. Since the machine operates on a continuous basis, it reduces downtimes and accelerates the project schedules. Another characteristic of drum mixers is the fact that they require less maintenance, have a small size, and operate efficiently, which all add to reduced operating costs. Their single-unit nature means that they are easy to install, operate and transport and their flexibility is unmatched by other products available in the market that deal with multiple or distant work areas by the contractors.
The current asphalt drum mixers have complex automation options including real-time temperature control, accurate feeding of the materials and burners that are fuel efficient. These technologies assist in the production consistency and in making the end product of asphalt mixes to be of the required standard on issues of strength, durability, and smoothness. It also has eco-friendly dust collection systems to minimize emissions and ensure that they meet the environmental regulations.
To conclude, asphalt drum mixers have proven to be very productive in terms of cost of operation, reliability of operation and continuous production, they are therefore an ideal option to any road construction company that wants to produce high quality asphalt with a high level of productivity.
