You need to know bulk density to work with any powder or bulk solid. This guide lists thousands of materials and is intended to be a reference tool to assist you in conveyor specification and designing your production system. Because the bulk density of a substance varies greatly depending on how the material has been handled, the information contained in this reference tool should be used for estimation purposes only in your bulk material handling application. To calculate material density, you can scroll through the entire list or start typing the name of a compound in the search field. All materials containing those characters will be displayed. Discover the information you need to know to work with any type of power or bulk solid. In seconds you can locate the bulk density of over 1,700 materials right at your fingertips. Use this app as a reference to determine bulk density for the material in your process. Bulk density of any substance can vary depending how it has been handled, but this tool can be very helpful in giving you an estimate.
