Abstract:
The mixing of material particles is a vital operation in numerous industrial
applications such as pharmaceuticals, polymers, ceramic, cosmetics, food, agricultural.
To determine the parameters related to the mixing process that are suitable for that
product such as material loading arrangement, mixing rotation speed, material's
coefficient of static friction, etc. The Discrete Element Method (DEM) analysis process
was used to create various models to study the effects of various parameters on mixing
quality. Where Lacey's mixing index is used to describe the quality of the mixing and
movement of the particles. In the case the effect of mixer rotation speed on mixing
quality. The speeds used in the analysis were 25, 50, 75, and 100 RPM The high mixing
speed here is 100 RPM This resulted in the material being dispersed faster than the
low mixing speed. In the case of examining the effects of the adhesion properties of
material particles the material with a low Coefficient of static friction (µ.), in this case µ = 0.2, causes the material to disperse faster than a material with a high Coefficient of static friction (µ) value. In the case of effects from the material particle loading
pattern It can be concluded that the top-bottom material particle loading pattern
affects the material to disperse faster than the left-right material particle loading
pattern.
