What are the industrial steps involved in manufacturing bitumen emulsion using a colloid mill?

Industrial production typically includes preparing the aqueous phase with water, emulsifier, pH adjustment, and any stabilizers, then heating the bitumen to the target viscosity. Both streams are metered to a colloid mill where dispersion occurs at controlled shear, temperature, and flow rate. The product is cooled or stabilized, then transferred to storage with gentle pumping and minimal air entrainment. QC tests are performed per batch such as residue content, viscosity, stability, pH, particle charge, and breaking behavior before release for delivery.
