Drum Mix Asphalt Plant

A continuous plant that dries and mixes in one drum — simpler, lighter and lower in cost, ideal for steady production of one mix.

Models: RMX-D40 ~ RMX-D160

Certifications: ISO 9001
Warranty: 12 months

Best for: Rural roads, base courses and county programmes that need steady output of one mix at the lowest cost per tonne.

Continuous drying and mixing in a single drum
Fewer components — simpler operation and maintenance
Lower investment and fuel use per tonne for standard mixes
Available in stationary or trailer-mounted layouts

Simple, continuous production

In a drum mix plant, cold aggregate is proportioned by belt feeders and enters one rotating drum. The front section dries and heats it; further along, bitumen and filler are added and the mix leaves the drum continuously into a storage bin.

Where it makes the most sense

Drum plants shine on work with one main recipe and steady demand: rural and county roads, base courses, and maintenance programmes where the lowest cost per tonne matters more than recipe flexibility.

Limits to know

Recipe changes are slower than on a batch plant, and some specifications call for batch production. If that applies to your contracts, compare the stationary batch plant or the containerized plant.

How the RMX-D works, step by step

Cold feed: each aggregate size is metered from its bin by a variable-speed belt feeder.
Weighing belt: the combined aggregate passes over a belt scale, so the control system knows the tonnage entering the drum.
Drying zone: the burner heats and dries the aggregate in the first part of the drum.
Mixing zone: bitumen is sprayed in, in proportion to the measured aggregate flow, and filler is added; the drum mixes the material as it travels.
Discharge: finished mix leaves the drum continuously into a storage bin or straight to trucks.

Choosing an RMX-D model

Model	Rated output	Daily output, 8 h at 75%	Typical work
RMX-D40	40 t/h	about 240 t	Village roads, small municipalities
RMX-D60	60 t/h	about 360 t	Farm-to-market and rural road programs
RMX-D80 / D100	80–100 t/h	480–600 t	County roads, base courses
RMX-D120 / D160	120–160 t/h	720–960 t	Larger programs with one main mix

Drum mix or batch: a quick decision table

If your project…	Choose
Uses one or two mixes for months at a time	Drum mix
Changes recipes several times a day or serves many customers	Batch
Has a specification that requires batch weighing	Batch
Needs the lowest cost per ton on rural roads	Drum mix
Has variable stockpiles and little room to control them	Batch

Keeping quality steady on a drum plant

Because there is no hot screen, the mix follows the cold feed closely. Good practice is to keep separate, well-graded stockpiles, cover fine aggregate against rain, calibrate the belt feeders and weighing belt regularly, and check gradation and binder content from production samples every shift.

Options

Trailer-mounted layout, finished mix storage silo, baghouse or wet dust collector, burner fuel choice, extra bitumen tank, cold RAP addition at modest rates, and generator power.

Price range

Indicative FOB prices for RMX-D plants run from about $55,000 to about $360,000, depending on output and layout. See the model-by-model price page and the price guide.

How a drum mix plant works

Drying and mixing happen continuously in one drum, giving steady output with a simpler structure. These are the main systems of the plant, in the order material flows through them.

1
Cold feed
Speed-controlled feeders deliver each aggregate size continuously, with a belt scale tracking the total flow.
2
Drying and mixing drum
The first part of the drum dries and heats the stone; further along, bitumen and filler are added and the mix leaves the drum without stopping.
3
Bitumen dosing
A metering pump adds hot bitumen in step with the measured aggregate flow.
4
Dust control
A baghouse or wet scrubber cleans the drum exhaust before it reaches the stack.
5
Controls
The PLC keeps feed rate, bitumen dosing and burner output in balance as production changes.

Frequently asked questions

What is the difference between a drum mix plant and a batch plant?

A drum plant proportions materials continuously and mixes them inside the drying drum; a batch plant weighs each ingredient per batch in a separate mixer. Drum plants cost less and run simply; batch plants handle frequent recipe changes and tight specs better.

Can a drum mix plant make surface-course asphalt?

Yes, for standard mixes with a consistent recipe. If your contract needs frequent recipe changes or strict specifications, a batch plant is the safer choice.

Is a trailer-mounted version available?

Yes. The drum plant can be built stationary, semi-mobile or fully trailer-mounted depending on how often you plan to move.

Is a drum mix plant cheaper to run than a batch plant?

Usually yes for long runs of one mix: fewer moving parts, no screen or hot bins, and continuous production. The advantage shrinks when recipes change often, because each change takes longer to stabilize.

Can a drum mix plant produce surface course?

Yes, if the specification allows continuous production and the aggregate stockpiles are well controlled. Some highway and airport specifications require batch plants, so check your contract first.

How much does a drum mix plant cost?

Indicative FOB prices for RMX-D plants run from about $55,000 (40 t/h) to about $360,000 at the top of the range; an 80 t/h stationary drum plant is typically around $90,000. See the price guide for more detail.

What dust collector does a drum plant use?

A baghouse is recommended where emission limits are strict or filler should be recovered. A wet dust collector costs less and suits some remote sites, but it needs water and settling ponds.

Can a drum mix plant be trailer-mounted?

Yes. RMX-D plants can be built stationary, semi-mobile or with the main units on trailer chassis for frequent moves.
