CEI portable Asphalt-Rubber Blending Plants produce a consistently high quality product at the highest continuous production rate available in the market. Highly accurate mass measurement controllers, and a fully automated PLC control system ensure product compliance with a minimal amount of operator functions. The component selections are based upon reliable and readily available suppliers. When service is required, you are assured that it is not only available but also affordable.

Shrouded high speed augers in the bot-tom of the holding tank agitate the mix to keep the crumb rubber in suspension.

Portable Mixing UnitGround Tire Rubber (GTR) is loaded into the hopper before mixing begins and must be replenished during the mixing process. Next the screw conveyor carries the GTR to the mixing chamber. Then, the GTR is blended with virgin asphalt by a high shear mixer running at a speed of 3400 rpm. As the materials are mixed, they are pumped to the portable holding tank. During the mixing process, fresh materials are continuously fed into the chamber until the required volume of material has been mixed.

One compartment in the Portable Holding Tank contains fresh mix for a specified time while aged mix is used out of another compartment to make Hot Mix Asphalt (HMA). Each compartment has an auger mounted horizontally in its lower compartment. The auger agitates the mix to keep crumb rubber in suspension. The augers in each compartment operate independently. A level float system diverts the hot oil flow if the asphalt-rubber drops below the top of the heating coils.

The CEI Portable Mixing Unit includes the high temperature heating system for the process. Load Cells and Mass Liquid Flow Meters provide extremely accurate material regulation. And the controls can be either panel mounted or included in an air conditioned con-trol room. Low emission options are available for the hot oil heater.

The CEI Portable Reaction Tank can be a single, double, or triple compart-ment design. Each compartment has individual controls for level and tem-perature. Blue smoke control, folding walkways and plant supply pumping/metering systems are all inclusive. Axles are provided per permitting requirements.

Equipment. Parts. Service. Rely on CEI. A legacy of innovation and quality since 1969.

Controls automatically maintain the ratio of asphalt-to-GTR set by the operator. The system incorporates a Program-mable Logic Controller (PLC), a mass flow asphalt meter and load cells. The PLC controls the flow of materials into the mixing chamber based on information provided by the asphalt meter and load cells. The mass flow asphalt meter, located in the asphalt line, monitors the flow of asphalt into the mixing chamber. The load cells are mounted on the GTR hopper and monitor the amount of GTR being fed into the chamber. Running totals of asphalt and GTR are displayed so the operator can verify that the set mix ratio is being achieved.

Nominal Continuous Capacity RatingBlending Trailer 35 to 45 Tons Per Hour

Reaction Tank Single Compartment Double Compartment Triple CompartmentTons Per Hour 10 to 15 15 to 22 25 to 34Nominal capacity ratings are based upon a continuous 24 hour per day plant supply delivery in compliance with normal specifications for reaction time and temperature. Actual continuous production rates are influenced by the compatibility of the virgin asphalt with the crumb rubber, piping system designs, specified reaction times, temperatures, etc.
