Some materials present a risk for combustible dust explosion or harmful environmental impact, so the system needs to ensure that the material is contained and processed in a way to remove manual handling and eliminate fugitive dust. Before selecting a vacuum conveying system for powders, here’s what to consider…READ MORE.
