Mbinu za majaribio ya ugumu wa diski zimetumika sana katika kupima uharibifu wa kaboni yenye nguvu ya granular. Mfano wa ssa-39 unajumuisha diski maalum ya shaba ya kipenyo cha 8in (203mm) na mipira ya chuma 15 ya kipenyo cha 1 / 2 inchi (12.7 mm) na 3 / 8in (9.5 mm). Mzunguko diski ina maalum 8mm unene shaba chini ya sahani, katika 1092mm ndani ya radius, na unene kati yake ni 3.2mm. Plate ya chini imewekwa ndani ya mfumo wa kiwango wa urefu kamili wa screen na ina makali ya kupanua kwa ajili ya 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).
