Obviously the two go hand in hand, and that’s the way it is with all asphalt plant systems: An improvement or efficiency in one area has an impact on others. The advantages of an efficient cold feeder are significant. To put it simply, the proper calibration means you only heat what you need. And that leads to these benefits: Reduced fuel costs.
