Vortex’s design philosophy is to develop products that compensate for wear, require minimal spare parts, provide in-line maintenance, and maintain a longer service life than market alternatives. Vortex offers a wide range of solids handling components for dry bulk material handling application.
The Specific Gravity - SG - is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature. It is common to use the density of water at 4 o C (39 o F) as reference - at this point the density of water is at the highest.. Specific gravities - SG - for common solids and metals can be found in the table below:
Apparent specific gravity is intended to only measure the specific gravity of the solid volume, therefore it will be the highest of the aggregate specific gravities. ...

How to Obtain the Specific Gravity of Dry Solids. To obtain the per cent solids in a pulp, from the specific gravity of that pulp, the specific gravity of the dry solids in the pulp must be known. The following is a simplified procedure for obtaining this figure. Place a weighed amount, say 200 grams, of dry solids in a dry graduate.
