Dry Bulk Material
General Characteristics Database
These are General Characteristics
In this online database, we provide general characteristics for some dry bulk materials for informational purposes only, presented with no warranty and may include inaccurate information, as every material can have different grades with wildly different characteristics. Different grades of the same material can behave quite differently from each other inside of a pneumatic conveying system. It is advised to provide a specific sample of the material to be conveyed to your pneumatic conveying company so they can design the system to the exact specifications of the material and the physical location of the equipment.
