What inspections and refurbishments are required before purchasing a used bitumen emulsion plant?

A used plant must be inspected for colloid mill wear, rotor-stator clearance, pump condition, and corrosion in tanks and pipelines. Control systems, dosing accuracy, and heating circuits should be verified and recalibrated. Residual contamination from incompatible emulsions must be removed. Refurbishment often includes seal replacement, instrumentation upgrades, insulation repair, and automation updates. A test production run with lab verification is essential before commissioning.
