Testing a High-Speed Disperser With Your Own Liquid Batch
A buyer's guide to planning a disperser demonstration around the buyer's actual liquid material, with practical questions on batch size, speed range, and acceptance criteria for the RFQ and trial run.
Before accepting a disperser demonstration, decide whether the supplier will run your own liquid formulation at your intended batch size, not a generic sample. A trial on your material reveals more about mixing behavior than any catalog figure.
Ask the supplier to confirm the demonstration batch volume within the 200–1,000 L range and to state the motor power of the unit used; the reference catalog lists 22 kW and a rotation speed of 0–1,440 rpm, but treat these as reference values only and confirm what the offered model actually provides. Request that the trial cover the low and high ends of the speed range you expect to use, and agree in advance how you will judge dispersion quality, such as visual uniformity or a sampling method you specify.
For the RFQ, ask whether the demonstration unit matches the proposed configuration, what material quantity you must supply, and how results will be recorded. For acceptance, define pass criteria tied to your formulation rather than to the supplier's standard test material.
Before requesting a quote, confirm with the supplier the batch size and speed range of the exact model offered, the motor power, the material quantity needed for a trial, and how demonstration results will be documented.
