—Why Does It Determine Powder Flowability and Mixing Difficulty?In powder engineering, many parameters are used to evaluate powder behavior, including:Particle size;Particle size distribution;Angle of repose;Bulk density;Tapped density;Flowability;Cohesion.However, one of the most fundamental proper
1. IntroductionVacuum drying is an advanced industrial drying technology that removes moisture or organic solvents from materials under reduced pressure. By lowering the pressure inside a sealed drying chamber, the boiling point of liquids decreases significantly, allowing evaporation to occur at mu
