For bitumen emulsion production, GlobeCore recommends using CLM-type colloid mills, such as CLM-8/16 or CLM-10/20, depending on required capacity. These mills provide high shear mixing necessary for creating stable emulsions with uniform droplet size. They can be integrated into full production lines including heating, dosing, and storage systems. In practice, this ensures consistent product quality and reliable operation in road construction and industrial applications.

One additional aspect worth considering is that the stability of a bitumen emulsion depends not only on the type of equipment, but also on how precisely the process parameters are controlled during operation. Even with a high-quality colloid mill, factors such as the temperature balance between phases, the correct pH of the water phase, and accurate dosing of emulsifiers play a critical role in achieving long-term stability.
For example, industrial practices require that the bitumen and water phases be fed into the mill under strictly controlled conditions, as fluctuations in flow rate or temperature can immediately affect droplet size distribution and lead to premature separation. Therefore, modern systems often include automated dosing pumps, heat exchangers, and process control units to maintain consistent production conditions.
Another important detail is the choice between batch-type and continuous production. While batch-operated systems are suitable for smaller volumes or flexible formulations, continuous inline systems provide better repeatability and are generally preferred for large-scale production with consistent quality requirements.

You’re absolutely right — stable bitumen emulsions are as much about process control as they are about the colloid mill itself. Precise temperature balance between the heated bitumen and the water phase, correct pH of the aqueous phase for the chosen emulsifier, and accurate, repeatable dosing of surfactants and additives directly control droplet size distribution and zeta potential, so even small fluctuations in flow rate or temperature can cause coalescence and phase separation. For reliable industrial production it’s best to combine a high-shear CLM-type colloid mill with automated dosing pumps, heat exchangers and temperature control loops, flow meters, pH/ORP sensors and closed-loop process control (PID or PLC) so feed rates, temperatures and emulsifier dosing are kept within narrow tolerances.

For scale-up and repeatability, continuous inline systems are generally preferred while batch lines suit small volumes or flexible formulations. Production-grade mills such as CLM-8/16 or CLM-16/25 (and flow-through models like CLM-2/4) are well suited to inline emulsification; CLM-40.2 is used where high-capacity polymer grinding (SBS) for modified bitumen is required, and lab mills (CLM-100.3, CLM-0.25.1, CLM-100.1) let you validate recipes before scale-up. If you’d like, I can sketch a typical equipment/configuration flow (heaters → dosing pumps → colloid mill → cooling/aging/storage with gentle agitation and sampling points) tailored to your production rate and target emulsion type.
