SPHERES INFORMATION

These minerals have unusually round particle shapes. Some are very strong while others are hollow and light weight.

Mineral Beads 45 Filter Aid

MINERAL BEADS 45 FILTER AID INFORMATION

Kam Grade 45 is produced by the selective milling of expanded Volcanic Ash followed by chemical fusion and air classification. A naturally occurring glass, it is inert, tasteless, odorless and only slightly soluble in water or mineral acids.

Permeability Flowrate (volume basis)———- 85 to 115
50 is available upon request.
Filter Cake Density (pounds per cubic foot)— 14.5 to 15.5

EFFECTIVE VOID VOLUME (PER 100 POUNDS) = 5.0 CUBIC FEET
