Critical Design Factors

    Maximize Polymer Efficiency

  • When a polymer is poorly mixed and not fully incorporated with the base asphalt, it does not contribute to the performance of the asphalt binder Performance – When we are talking about Polymers, we are really talking about elastomers which is a subset of polymers. They are rubber like a rubber band and rubber that makes tires. These materials recover to the original size and shape after stretching or using a force on them. When “polymers” are used successfully, they do that to roads improving the performance and longevity. If they are not mixed well and not fully incorporated, it is a waste of time, resources, and money because ultimately, they don’t improve the performance of the road. and, by extension, will not contribute to the performance of the road.
  • Successful incorporation of polymer into base asphalt results from high sheer. With high sheer mixing, polymers incorporate more completely and faster resulting in a greater return on investment and with lower cycle times.
    Speed of Processing

  • Polymer needs time and energy to go in. Low shear mixing requires more time (anywhere from 2 to 24 hours to fully incorporate).
  • High shear mixing with a colloid emulsion mill drastically reduces mix time.
    Equipment Durability

  • A Bergkamp colloid emulsion mill is engineered for durability in the following ways:

  1. Rotor/stator is composed of alloys to resist abrasion of polymers and the mineral fillers that come with the polymer
  2. All wetted parts (asphalt metal contact) are constructed of stainless-steel alloys
  3. Silicon carbide sleeve bearings
  4. Pressurized double mechanical seal system
  5. 5-year warranty

Key Features

  • Provided as a complete package with mill, motor, and seal lubrication system
  • Milling zone with pattern of grooves and teeth for efficient droplet dispersion
  • Variable gap adjustment to control particle size distribution
  • Low relative power consumption
  • All wetted parts made of durable stainless steel construction
  • Low noise
  • Available in sizes from 6 to 60 t/h and in a laboratory version of 300 l/h
