WRT Cold Mix Plant

Presenting the world's first cold mix plant!

This portable (mobile), modular continuous-flow (Drum-Mix) plant for production of high quality cold asphalt mixes with the aggregate heating/mixing temperature of 47-68 °C, has been specifically engineered at the request of Cantat Associates Inc. with the purpose of providing a highly efficient and economical solution, requiring minimal energy and fuel consumption, which will allow you to establish your own cold mix asphalt production with minimal capital investment. The entire CMP cold mix plant, including the drum mixer/heater, aggregate hopper (fraction 5-10 mm), discharge conveyor, AC/bitumen feeding and metering system and other required and optional components, can travel on a single trailer.

This modular WRT CMP plant offers additional/optional components and modules and can be fully adapted to satisfy your current or future production needs, both in produced capacity (tons per hour) and in the types of mixes that you wish to produce - by adding several optional modules to an existing plant, you will also be able to produce warm and hot mix asphalt.

Features:
  • Various ranges of production capacity: from 7 to 30 tons per hour, from 12 to 45 TPH (by upgrading to a higher burner capacity), and from 70 to 100 TPH.
  • Extremely low fuel consumption - only 1 liter/ton of cold asphalt mix!
  • Allows for easy start-up, installation and maintenance.
  • Has a simple plant design that requires just one plant operator and one loader operator.
  • Has a high operating efficiency that ensures reduced fuel and energy costs and low cost-per-ton production.
  • Operates on multiple fuel types.
  • Compact, allowing for lower cost standard freight shipping worldwide in a single sea container.
  • The aggregate heating can be performed using 2 types of fuel sources for the burner: fuel oil (diesel) and/or gas (natural gas), depending on the customer requirements (a combination diesel/natural gas burner is available). Mazut can also be used.

The plant can be either mobile with a single axle, or stationary for production indoors.

We offer 2 types of base plant configurations:
  1. Manual control of raw material feed (aggregate and AC/bitumen).
  2. Automatic control and metering of raw material feed (aggregate and AC/bitumen). This base configuration must be selected if the customer is planning a future upgrade to facilitate warm/hot mix production.

Additional / optional:
  • Electric vibrator for cold feed hopper.
  • Combination burner - fuel oil (diesel) and gas (natural gas) with gas manifold.
  • Heated enclosure for asphalt pump skid - maintains asphalt pump system temperature during shutdown periods.
  • 1025 kWh (3.5 million BTU/h) for increased cold mix asphalt production capacity (up to 45 TPH).
Retrofitting with additional modules for warm and hot mix asphalt production

At any point in time, the plant can be retrofitted with additional modules, allowing the customer to produce cold, warm and hot asphalt mixes at the increased capacity of (up to) 45 TPH.

Supervised installation and plant start-up

A qualified WRT engineer will be provided for installation supervision, plant start-up and training of the local personnel.

Warranty

1 year from plant start-up.
