Stationary Batch Asphalt Plant

Warranty
12 months

Best for: Asphalt producers and contractors running one site for years, with many mix recipes and strict specifications.

  • Separate weighing of aggregate, filler and bitumen for every batch
  • Quick recipe changes for different layers and customer orders
  • Room for larger hot-mix storage, extra silos and RAP additions
  • Coal, oil or gas burners to match local fuel supply

The workhorse for long-term supply

A stationary batch plant dries and heats aggregate in a rotating drum, screens it into hot bins, then weighs aggregate, filler and bitumen for each batch before mixing. Because every batch is weighed, one plant can switch between base, binder and surface mixes — or between customers — during the same shift.

Who it suits

  • Commercial asphalt producers supplying many contractors from one location
  • Highway and airport work with strict mix designs
  • Long contracts where a permanent site and civil works make sense

Planning the site

Allow space for aggregate stockpiles, truck circulation, bitumen tanks and future additions such as extra storage silos or a RAP line. If you expect to move within a few years, compare the containerized plant, which needs no foundations.

Choosing an RMX-B model

Model Rated output Daily output, 8 h at 75% Typical use
RMX-B60 60 t/h about 360 t Municipal plant, small towns
RMX-B80 / B120 80–120 t/h 480–720 t Regional contractors, provincial roads
RMX-B160 / B200 160–200 t/h 960–1,200 t Highway contracts, commercial supply
RMX-B240 / B320 240–320 t/h 1,440–1,920 t Expressways, large commercial plants
RMX-B400 400 t/h about 2,400 t Metropolitan supply, mega projects

Commercial producers should also size hot mix storage: two or more silos let the plant run steadily while trucks from different customers arrive unevenly.

Site layout essentials

  • Stockpiles: separate bays for each aggregate size, with covered storage for sand and fines to control moisture
  • Traffic: one-way truck loop under the tower or silos, and a separate loader route to the cold feed bins
  • Bitumen area: tanker unloading, tanks and heating with spill containment
  • Utilities: power supply sized to installed kW (178 kW for the RMX-B60 up to 960 kW for the RMX-B400), water for dust control, and fuel storage
  • Space to grow: room for an extra silo, more bitumen tanks or a RAP line

Why batch production matters for specifications

A batch plant screens the hot aggregate and weighs every component for each batch. When stockpile gradation drifts, the hot bins absorb part of the change; when the recipe changes, the next batch follows the new formula. That is why many highway and airport specifications favor batch plants, and why commercial plants serving several customers are usually batch plants.

Options

Hot mix storage silos, extra bitumen tanks, thermal-oil heating, coal powder or dual-fuel burners, RAP line, fiber and additive feeders for SMA, insulation for cold climates, and an asphalt laboratory set.

Price range

Indicative FOB prices for RMX-B plants run from about $115,000 (60 t/h) to about $1.0 million (400 t/h). See the model-by-model price page and the price guide for the capacity breakdown.

How a batch mix plant works

Every batch is weighed before mixing, so each ton of asphalt meets the selected formula. These are the main systems of the plant, in the order material flows through them.

  1. 1

    Cold feed

    Four to six hoppers each hold one aggregate size; belt feeders with speed control release them in the ratio your mix design calls for.

  2. 2

    Dryer and burner

    The rotating drum tumbles aggregate through the burner flame until moisture is driven off and the stone reaches mixing temperature.

  3. 3

    Hot elevator

    Buckets carry the hot aggregate up to the screen at the top of the mixing tower.

  4. 4

    Screening

    A vibrating screen splits the hot stone into size fractions again, correcting any variation from the cold feed.

  5. 5

    Hot bins

    Each fraction waits in its own insulated bin so it can be weighed exactly.

  6. 6

    Weighing and mixer

    Stone, filler and bitumen are weighed per batch, then blended in a twin-shaft mixer before discharge to trucks or a storage silo.

  7. 7

    Baghouse

    Fabric filters catch the fine dust in the dryer exhaust; recovered fines can be returned to the mix as filler.

  8. 8

    Control room

    A PLC system runs the sequence, stores recipes and logs each batch for quality records.

Frequently asked questions

Why choose a batch plant over a drum mix plant?

Batch plants weigh every ingredient for each batch, so switching recipes and meeting tight specifications is easier. Drum plants are simpler and cheaper but best for long runs of one mix.

What foundations does a stationary batch plant need?

Concrete foundations under the mixing tower, drum, baghouse and silos. We provide foundation drawings with loads so a local civil contractor can build them.

Which output should I choose?

Size the plant on your average daily tonnage and effective hours rather than the busiest day, and check that trucks and pavers can keep up. Send us your figures and we will propose a model.

How long does it take to build a stationary asphalt plant?

After the foundations have cured, steel erection, equipment installation, wiring and commissioning of a mid-size plant typically take several weeks. Foundation design and concrete work should start while the plant is being manufactured.

What foundations does a stationary batch plant need?

Reinforced concrete foundations under the tower, drum, baghouse, silos and tanks. We send foundation drawings with loads and anchor positions; a local civil engineer adapts them to your soil conditions.

Which RMX-B model is right for commercial asphalt supply?

Commercial plants serving several contractors usually choose 160–240 t/h with hot mix storage silos, so trucks from different customers can load without waiting for the next batch. Busy metropolitan plants go to 320–400 t/h.

How much does a stationary batch plant cost?

Indicative FOB prices for RMX-B plants run from about $115,000 for the 60 t/h model to about $1.0 million for the 400 t/h model, depending on configuration. The price guide shows the ranges by capacity.

Can I add RAP recycling to a stationary plant later?

Yes, if space is planned for it. Cold RAP can be added through a feed collar at modest rates; higher RAP content needs a separate RAP drum and heated weighing, which is easiest to plan at the layout stage.
