1. What is an Asphalt Drum Mix Plant?
Answer: An Asphalt Drum Mix Plant is a continuous type of hot mix plant used for producing asphalt. It mixes aggregates and bitumen in a drum, continuously producing hot mix suitable for road construction.
​
2. How is it different from a Batch Mix Plant?
Answer: A Drum Mix Plant operates continuously, mixing materials in a single drum, while a Batch Mix Plant processes asphalt in separate batches. Drum plants are faster and more economical, ideal for large-scale road projects.
​
3. What are the typical capacities available?
Answer: Asphalt Drum Mix Plants are available in various capacities, commonly ranging from 40 TPH to 120 TPH, depending on the model and requirement.
​
4. What are the main components of the plant?
Answer: Key components include the cold aggregate feeder bins, drying & mixing drum, burner, bitumen tanks, control panel, mineral filler unit, and pollution control unit (bag house or wet scrubber).
​
5. What type of burner is used in Drum Mix Plants?
Answer: Burners can be diesel, LDO, furnace oil, or gas-fired, and are used for heating aggregates inside the drum. Efficient combustion ensures proper asphalt mixing and drying.
​
6. Can recycled asphalt pavement (RAP) be used?
Answer: Yes, many modern plants support RAP usage to reduce costs and promote sustainability. However, specific design adjustments may be needed.
​
7. What is the role of the pollution control unit?
Answer: It helps capture dust and particulates during production to meet environmental norms. Typically, a bag house filter or wet dust collector is used.
​
8. How is temperature controlled during production?
Answer: The control panel monitors and adjusts the drum temperature and burner flame intensity, ensuring optimum mixing temperature of aggregates and bitumen.
​
9. Is the plant easy to transport and install?
Answer: Yes, most Asphalt Drum Mix Plants are SKID-mounted or mobile, allowing for easy transportation and quick setup at project sites.
​
10. What is the lifespan of a typical Asphalt Drum Mix Plant?
Answer: With regular maintenance and proper usage, these plants can last 10–15 years or more, depending on build quality and operating conditions.
