Samples are automatically taken from the production line, the machine tests the pellets by agitating them with air at a fixed 70mBar pressure, returns them to the line, and a PDI result is provided to the NHP300 control software, or to your current mill management software without manual input from the mill operator during the test phase.

Taking a sample from the process line enables changes to be made at a point that will maximise production, reduce cost, minimise waste and maintain pellet quality.

In addition to calculating the PDI, the amount of ‘dust’ (Fines) can be also be calculated.
Up to four pellet lines can be tested by one NHP300 with the option to return samples back to their original lines too.
