Determining the Specific Gravity of Dry Solids
The desired sample should be dry and between 10 mesh and 100 mesh (Tyler). Hang the dry, empty container on the scale and pour in the dry sample of dry material until the pointer indicates 1.000 Kilograms on the outer ring of the dial (the container now has 1.000 Kg of material in it). Pour the sample onto a rolling cloth or sheet of paper. Fill the container one third full with clear water and gradually stir in the dry sample. Insure that the sample is thoroughly wetted and that air bubbles are eliminated. Hang the container on the scale and add clear water up to the overflow holes. Read the dry solids specific gravity on the innermost ring of the dial chart.
Determining Percent Solids
If you know the specific gravity of the dry solids in the pulp (see determining the specific gravity of dry solids), you can directly read the percentage in the pulp on the dial chart. Select the correct dial face for the particular dry solid specific gravity in the pulp. Hang the filled container on the scale. The percent solids in the pulp read clockwise from the specific gravity number on the green, white and red rings of the dial chart.
A reading of 44% solids at 2.2 specific gravity also reads 39% solids at 2.6 specific gravity and 35% solids at 3.2 specific gravity.
