Differences in the dynamics of powder densification involving bizarre and Rotary Tablet Press Machine have been pointed out by squeezing at distinct compression pressures microcrystalline cellulose, lactose monohydrate along with dicalcium phosphate dihydrate and regaining the corresponding stress/strain data in the two machines outfitted to track punches displacement and compression forces. Heckel plots were subsequently obtained from those stress/strain data. Curves got from the inkjet machine have a thinner zone of linearity for the calculation of P(Y) and D(A). The impact of this various compression mechanism of this inkjet machine on the form of this Heckel plot is more noticeable at a non-deforming substance like dicalcium phosphate. The effect of this longer dwell time of the rotary system about the porosity reduction happening following the maximum strain was attained, is more evident at a ductile material like microcrystalline cellulose. Heckel parameters obtained from the cage press are in some cases different from those retrieved from the bizarre machine due to the longer dwell time, machine deflection and chalk leaning happening in the rotary machine, even though they could better explain the substance densification at a Automatic High Speed Rotary Tablet Press Machine.
