Even though the ordinary passive acoustic emissions indicated no adjustments, the kurtosis with the emissions measured within the air outlet indicated the entrainment of fines read more from your bed. Kurtosis suggests the relative peakedness in the distribution of values within a signal. Kurtosis is calculated by:

The utility with the fluid mattress drier will come into play right here. To ensure that processes like drying, mixing, finishing, granulation, and cooling are attained during the exact same cycle, it is feasible to combine an it which has a granulation system.
Solutions: Clean the filter as per the supplied frequency or throughout batch changeover cleansing. Examine the tension gradient inside the manometer or alarm through the process.
