The High-volume cascade impactors attached to any high-volume air sampler fractionate suspended particulates into as many as six different size fractions. The slotted impactor design separates particulates from larger than 7.2 μm to less than 0.49 μm while operating at a flow rate of 40 cfm. The cascade design of this impactor collects particles on small …

In roller compaction, the nip angle defines the critical transition interface between the slip and nip regions which is used to model material densification behavior and the …

The calculated nip angles were validated against those obtained from physical measurements during actual roll compaction. These nip angles were in agreement for various powder formulations containing plastic and brittle materials. The nip angles ranged from 4° to 12° and decreased significantly when the proportion of brittle material increased.
