SSA-39Gilson Ball Disk Hardness Test Taylor Sieve Strength Test Disk Hardness Test Disk

The ball and disc hardness test method has been widely used to determine the degradability of granular activated carbon. The SSA-39 model consists of a special 8-inch (203mm) diameter brass ball disc and 15 1/2-inch (12.7 mm) and 3/8-inch (9.5 mm) diameter steel balls. The spherical disk has a special 8mm thick hard brass base plate with a radius of 1092mm and a thickness of 3.2 millimeters at its center. The bottom plate is installed within a standard full height screen frame and has extended edges for stacking.

The ball-pan hardness test method has been widely used for determining degradation resistance of granulated activated carbons. Model SSA-39 set consists of a special 8in (203mm) diameter brass ball-pan and 15 each steel balls of 1/2in (12.7mm)and 3/8in (9.5mm) diameter. The ball-pan has a special 8mm thick hardened brass bottom plate dished out at 1,092mm inner radius to give a 3.2mm thickness at its center. The bottom plate is mounted in a standard full-height sieve frame with extended rim for stacking.

In use, a 100ml sized sample is placed in the ball-pan with the 30 steel balls and run for 30 minutes in a Sieve Shaker. The heavy ball-pan is loosely stacked (free to rotate) with five regular 8in sieves, sieve pan, and cover. “Hard-ness” of the activated carbon sample is determined by degradation resistance as measured by sieving the ground sample. The SS-30 Ro-Tap, sieves,sieve pan, and cover are all available from Gilson if needed. Est. Ship Wt.: 6lb (3kg).
