Drying & Mixing Asphalt Drum

A combination of complex flight design and heat transfer technology creates an in-demand drying and mixing unit. As leading asphalt suppliers, we are devoted to developing world-class machines incorporated with the latest innovation that adds a competitive edge to your business. Our CMPL thermodrum unit comprises a triple heat transfer system that facilitates maximum heat transfer to the aggregates. It helps enhance productivity, reduce fuel consumption, and prevent bitumen oxidation. Connective, conductive, and radiation methods transfer heat to the aggregates. Coninfra Machinery Pvt. Ltd. (CMPL) supplies a comprehensive line of high-performance asphalt drum mix plants to meet the varying needs of producers.

Filler Storage Unit

Coninfra supplies a broad spectrum of filler storage and feeding solutions that enable our customers to choose according to their site requirements. A computerized metering system with variable speed guarantees the right proportioning in the asphalt drum mix.

Bitumen Injection

The hot oil jacketed pump is regulated by an AC varying speed that compels the metered portion of Bitumen into the asphalt drum mix section. The arrangement makes the operation high-performing. SCADA/PLC/Microprocessor is 100% automatic. It provides accurate metering of bitumen.

Cold Aggregate Four Bin Feeder

With appropriate welding and modular design, the four bins allow easy addition of bins to cater to a customer’s growing requirements. Steep bin walls and valley angles enable the free-flowing of aggregates from the feeders without causing any bridge formation around the corners with sticky aggregates. Each bin features adaptable calibrated gate openings and variable speed feeder drivers. The system provides complete balanced control, better adjustability, and precision of operations.

Asphalt Drum Mechanics

The asphalt drum drive of the 30-120 TPH plants features a cradle shape design that provides low maintenance. The chain drive receives sufficient lubrication from an automatic lubrication system that ensures durability with hassle-free service. A four-wheel friction drive is a standard on the 120 TPH and higher models. Tunion rings and tunion rollers, sprockets, and thrust wheels are engineered for an effortless and dryer drum rotation. It adds to enhanced productivity in the long run.

Oversize Removal Vibrating Screen

The CMPL series asphalt drum mix plants feature large aggregate removal vibrating screens. They are placed at the end of the cold aggregate feeder. A comparatively large-sized material that can damage the mixing and heating of thermo drum internals is screened out to ensure greater performance and protection of the asphalt mix plant.

Pressure Jet Burner

Our burner unit has achieved an immense reputation for its fuel efficiency, high uptime, and smooth operation. It is backed by a fully automatic remote control system with atomized high pressure. In combination with system interlocks, the automatic control unit ensures conformity to high safety standards. The pressure jet burner is suited for LDO, Diesel, or FO as fuel. It is equipped with a remote control system to detect flame failure. It also has an electric spark ignition system. In addition, the distinct nozzle system enables cleaning during operations, thereby facilitating zero downtime.

Pollution Control Unit (Optional)

CV Series – Wet Dust Collectors

CV Series is our venturi-type wet dust collector with high efficiency. It meets the environmental standards in specific criteria. The turbulence-type venturi design guarantees flawless entrapment of the dust-laden exhaust gas. Large spray nozzles designed using stainless steel deliver clog-free operation and ensure minimum water makeup demands. Venturi throat is flexible and allows fine-tuning to get maximum cleaning efficiency for the asphalt drum mix plant operating conditions.

Bag House Filter Unit

Coninfra develops unrestricted airflow baghouse filters with cutting-edge technology. The emphasis is on asphalt drum application with specially treated filter components. The zero-maintenance design reduces emissions to 50 mg/Nm3 and satisfies international pollution control criteria. The unit is environmentally friendly and supports low operation costs with high durability.

Hot Drum Mix Storage Silo

As a long-established asphalt drum mix plant manufacturer, Coninfra offers a comprehensive range of custom solutions for asphalt storage. Our standard options range from MONOPAK to TWINPAK systems. We offer MONOPAK silos with storage capacities from 70to 80 tons. And we offer TWINPAK silos with storage capacities from 50 to 80 tons with an extra element of reserving varying drum mix designs. Customers can choose different storage combinations by opting for custom-made MULTIPAK designs. Every solution is delivered with an automated standard safety control system and interlock process. Skip hoist arrangements, swiveling loadout conveyors, and hot bucket elevators can be used with the storage silos.

Bitumen Heating Storage Solution

CMPL offers hot oil bitumen storage tanks and direct heating-type tanks for customers to choose from. Each product comes with a storage capacity ranging from 10 tons to 50 tons. Japanese design oil heater is integrated with the indirect heating tanks while the direct counterparts feature imported pressure jet burners equipped with an automatic system. Every CMPL storage tank has hot oil circulating systems, auto thermostatic controls, and jacketed bitumen pumps. To reduce heat loss, the tanks are thoroughly insulated.


The control cabin is integrated with an automatic computerized system and features several standard elements, including a distribution switchboard, electrical power control console, and sequence controls.

A user-friendly control system provides high performance and complete reliability. Other features include:

  • Fail-safe interlocks
  • Automatic process control system
  • Online fault detection
  • Online printing capability
  • Ability to print, store, and edit product details, mix proportions, and do more.
  • Facility to display process control parameters
  • Manual, semi-automatic, and automatic operation options
  • The control unit features numeric keys and function keys that allow operation without special skills.
