A short definition
An asphalt drum mix plant is a machine that makes hot mix asphalt continuously. Stone aggregate of different sizes is fed in at one end; a rotating, burner-heated drum dries it, heats it and coats it with hot bitumen; and finished hot mix comes out at the other end, ready to be loaded into trucks and laid by a paver.
What is hot mix asphalt?
Hot mix asphalt (also called asphalt concrete, bituminous concrete or blacktop) is graded stone, sand and mineral filler bound together with bitumen while hot. It is laid and compacted at temperature to form the flexible pavement layers of most roads: bituminous macadam, dense bituminous macadam and the wearing course on top.
The main parts in one glance
- Cold aggregate bin feeder
- Belt weigher and vibratory screen
- Slinger conveyor
- Thermo drum with burner
- Dust collector
- Bitumen and fuel tanks
- Mineral filler unit
- Load-out conveyor
- Control cabin
Each part is described with sizes on the asphalt plant components page, and the step-by-step flow is on the working principle page.
Who uses one?
Road contractors building national and state highways, municipal bodies maintaining city roads, rural road contractors, airport and port developers, and commercial asphalt suppliers who sell hot mix by the tonne.
How is it different from a batch plant?
A batch plant weighs ingredients separately and mixes them in a pugmill one batch at a time. A drum mix plant does everything in one continuous stream, so it is simpler and generally cheaper to own. Compare both on the hot mix plant page.
Vinayak drum mix plant range
Vinayak builds the DM-45, DM-50 and DM-60, covering about 40 to 120 TPH, as stationary or mobile plants. See models on the asphalt drum mix plant page.
FAQ
Frequently asked questions
Is an asphalt drum mix plant the same as a hot mix plant?
A drum mix plant is one type of hot mix plant. The other common type is the batch mix plant. Both produce hot mix asphalt.
What fuel does the drum burner use?
Vinayak drum mix plants use a high-pressure, fully automatic dual-stage burner that runs on diesel.
