hat industrial process steps and equipment are required to make bitumen emulsion with stable droplet size and long storage life?

Key steps include preparing a controlled soap solution, heating bitumen to the correct processing range, metered feeding of both phases into a colloid mill, and transferring the finished emulsion into designed storage with gentle agitation. Equipment typically includes bitumen heater and tank, water tank with dosing and pH control, emulsifier and acid dosing, colloid mill, low shear transfer pumps, filtration, and QC lab tools. Stability comes from consistent temperature balance, stable feed ratios, correct mill shear, clean lines, and appropriate tank design to prevent separation over storage time.
