Bergkamp Bituminous Solutions introduces a High Sheer Colloid Mill that can efficiently and cost-effectively produce asphalt emulsions that contain higher percentages of asphalt. The mill’s rotor and stator are designed with more teeth, placed closer together, to transfer greater shear energy into the materials, increasing the mill’s power and efficiency. Manufactured with a special steel alloy, the rotor and stator do not easily wear or corrode. Bergkamp’s mill is designed to produce consistent particle size distribution, improving breaking and curing time, as well as the emulsion viscosity. The mill’s PSD (particle size distribution) increases the shelf life of the emulsion and improves its ability to arrive intact at job sites. The mill is backed with a five-year warranty and onsite service.
