Hopper Design Principles Chemical Engineering

2016-1-1  δ. φ. Jenike [1] found that the hopper angle required to allow flow along the walls depends on the friction between the powder and the walls, the friction between powder particles, and the geometry of the hopper.Design charts originally developed by Jenike [1] provide allowable hopper angles for mass flow, given values of the wall friction angle and the effective angle of internal friction

Impact of Operating Parameters on the Breakage

2020-8-12  Dry mills are commonly used to grind talc particles [19,20,21,22,23,24]. However, wet milling is preferred for submicron talc production, since it is more difficult to obtain a very fine product in dry milling [25, 26]. Furthermore, wet stirred mills enable particle breakage to grinding limits [27, 28]. Material properties (particle size, shape), mechanical properties (Young’s modulus, hardness and fracture
