In this work, particle electrification in the Turbula and horizontally oscillating mixers were
investigated for adipic acid, microcrystalline cellulose (MCC), and glycine particles. MCC
and glycine particles acquired positive electrostatic charges, while adipic acid particles
attained negative charges in both mixers. Adipic acid (of sieved size larger than 500μm),
MCC, and glycine particles were monotonically charged to saturated values, and had
negligible wall adhesion. On the contrary, the adipic acid particles, both unsieved and …
