What technical parameters should be evaluated before purchasing a bitumen emulsion plant for sale?

Evaluate target emulsion grades, required residue range, and break behavior, then match them to plant capabilities. Key parameters include colloid mill power and adjustability, accurate metering of bitumen, water, emulsifier, and acid, and temperature control capacity for both phases. Check tank volumes for soap, bitumen, finished emulsion, and additives. Confirm materials compatibility with acidic systems, filtration stage, agitation design, and cleaning changeover method. Instrumentation for flow, temperature, pH, and density strongly affects repeatability and reject rate.
