A new CPP (Critical Process Parameter), in the form of batch loading was identified. It was found that there are two different regimes (quasi static regime and impact regime) in which a comil generally operates, and the effect of the CPP's (batch loading and impeller speed) on these regimes was studied.
The milling model described in Part 1 has been expanded to a three-level model with the addition of powder-dependent parameter function models with simple material characterization measurements as ...

Process Step Physical/ Chemical Change Parameters ...
Milling is an essential unit operation used for particle size reduction in solid oral dosage manufacturing. The breakage of particles in a comil is due to the intense shear applied on the particles between impeller and the screen. Breakage also occurs due to the impact from a rotating impeller. Particles exit the mill based on their size relative to the aperture size of the screen bores.

02-04-2017· A typical process optimization methodology includes a systematic identification of CQAs, CPPs, and a risk assessment to identify the critical selection of key parameters. A plan can then be drawn up, using a statistical design of experiments (DOE), which can be a full- or partial-factorial design, based on the availability of API and the number of runs that can be manufactured.

The values for these critical parameters may vary considerably. Typically, the amount of drug in the milling chamber is rather low, from 2 to 30%(wt), 9, 17, 18, 25-29 while the number/volume of the milling pearls/beads is rather high, 10–50% of the weight/volume of the slurry. The size of the nanomilling pearls is constant, between 0.5 and 1.0 mm. 9, 17, 25-27, 29, 30 The milling times and ...

Critical process parameters (CPP) in pharmaceutical manufacturing are key variables affecting the production process. CPPs are attributes that are monitored to detect deviations in standardized production operations and product output quality or changes in critical quality attributes.Those attributes with a higher impact on CQAs should be prioritized and held in a stricter state of control.
