Features & Benefits
- Available as a set which includes scale, plastic beaker and a full set of charts
- Requires no reference to seperate charts or tables, saves time and prevents errors in calculations
- Simply hang the filled container on the scale hook, read the information directly from the scale
- High quality internal parts ensure trouble-free operation and long life
- A majority of the internal components are manufactured in stainless steel or advanced polymers
- The scales correlates the specific gravity of the ore with the percent solids of the pulp
- This information is displayed on a circular scale for several specific gravities by use of a simple weigh scale
- The simplicity of the scale along with its many applications have made this a common feature at concentrators throughout the world
- The scale can be used for fast, accurate percent solids determinations at various points through-out a concentrator, enabling adjustments to be made to keep, for example, a grinding circuit running effectively
- A full inventory of spare parts and accessories is always available including buckets and charts
- All our charts and buckets are interchangeable with the Marcy Brand Pulp Density Scale Pulp Density Scales are often referred to as Pulp Density Balance, Specific Gravity Scale, Density Balance, Density Scale, Marcy Scale

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.
Example:
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.
