Ball-Pan Hardness Test Set determines the degradation resistance of granulated activated carbons. A sample is placed in the ball-pan with the steel balls and runs 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 ASTM Test Sieves, Pan, and Cover. The hardness of the activated carbon sample is determined by degradation resistance as measured by sieving the ground sample.
Ball-Pan Hardness Set includes 8in (204mm) Brass Pan, (15) 1/2in (12.7mm) Steel Balls, and (15) 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.
