Ball-Pan Hardness Test Set

Model: SSA-39
Price: $491.00

The Ball-Pan Hardness Test determines degradation resistance of granulated activated carbons. SSA-39 Ball-Pan Hardness Test Set includes SSA-41 8in (204mm) Brass Pan for Ball-Pan Hardness Test, and one set each of 15 SSA-43 1/2in (12.7mm) Steel Balls and 15 SSA-44 3/8in (9.5mm) Steel Balls. The Ball-Pan has an 8mm thick hardened brass bottom plate dished out at 1.092mm inner radius for a 3.2mm thickness at its center. The bottom plate is mounted in a standard full-height sieve frame with extended rim for stacking. The Ball-Pan requires a standard sieve pan to nest properly in the Ro-Tap sieve shaker.

A sample is placed in the ball-pan with the steel balls and run for 30 minutes in the SS-30 8in W.S. Tyler® Ro-Tap® Sieve Shaker. The heavy ball-pan is loosely stacked (free to rotate) with five standard 8in Sieves, Sieve Pan, and Cover. Hardness of the activated carbon sample is determined by degradation resistance as measured by sieving the ground sample.
