An asphalt drum mix plant, also known as a continuous mixing plant, operates without interruptions, unlike batch mixing plants that produce hot mix in distinct cycles.
This seamless process ensures a steady production of material. If you’re seeking to understand how an asphalt drum mix plant functions, this step-by-step guide will walk you through its operation.
Step-by-Step Operation of an Asphalt Drum Mix Plant:
Step 1: Loading Aggregates into Cold Feed Bins
The process begins by placing aggregates into cold feed bins of various sizes. These bins regulate the material flow with adjustable gates before delivering it to the drying drum.
Step 2: Single-Deck Vibrating Screen
Aggregates are then passed through a single-deck vibrating screen. This critical step filters out oversized particles, ensuring only suitable material proceeds to the drying drum.
Step 3: Weighing Conveyor
A weighing conveyor transports the sifted aggregates into the drying drum. Equipped with a load cell unit, it measures the aggregate weight, relaying this data to the control panel for precision mixing.
Step 4: Drying and Mixing Drum
Once inside the rotating drying drum, the aggregates undergo a two-phase process: the first half of the drum dries the material using internal flights, while the second half facilitates mixing with bitumen and filler material.
Step 5: Fuel Tank for Drum Burner
The fuel tank supplies the necessary fuel to the drum burner, enabling efficient heating and operation of the drum mix plant.
Step 6: Asphalt Storage Tanks
The tanks store and heat asphalt before mixing it with hot aggregates in the drum mixer, ensuring uniformity in the final asphalt mix.
Step 7: Filler Silo
The filler silo dispenses binding material into the drum mixer, adjusting quantities based on mix requirements for optimal composition.
Step 8: Pollution Control Systems
Environmental safety is a priority. Asphalt drum mix plants are equipped with two pollution control mechanisms:
Step 8: Pollution Control Systems
Environmental safety is a priority. Asphalt drum mix plants are equipped with two pollution control mechanisms:
Dry Dust Collector – Captures heavy dust particles from the drum.
Wet Dust Collector – Acts as a secondary filter, trapping finer particles that escape the dry dust collector.
Step 9: Load-Out Conveyor
The load-out conveyor transfers the final mix to a hopper or storage silo, from where trucks load it for transport to construction sites.
