Powders granulation

Plastic, virgin A plastic material in the form of pellets, granules, powder, flock, liquid, etc. that has not been subjected to use or processing other than what was required for its initial manufacture. It is not recycled plastics.

A second flow measurement to be considered during scale-up is the ability of the granulate/powder to fill the dies. This can most efficiently be monitored by punch force variability and individual core weight measurements. Acceptable weight control (<3% RSD) and force (<5% RSD) may be masked at slower compression speeds typically used for development or when a tablet press is not fully tooled. Production operations will tend to run at the high end of any validated range, so flow must be consistent from batch to batch. 

The flow function illustrated in Fig. 1 reveals a singular behaviour of the powders which may be associated with the process or with the high percentage of PVC. In fact, even if the curves were obtained by linear regression, a marked dispersion may be seen, particularly for the compaction of the mixture and, curiously, for the wet granulation powder.

The plate granulators ensure continuous granulation. Powdered aminoplast is supplied to an inclined rotary plate whereby it is lifted and then lowered. Agglomerating liquid is forced into the formed layer by injectors. The powder moistened with the liquid is pelletized. The formed pellets reaching a predetermined size are fed to the plate and then by gravity to an area wherein drying and subsequent sizing occur.
