球盘式硬度试验方法已被广泛应用于颗粒活性炭的降解阻力的测定。SSA-39模型由一个特殊的8in (203mm)直径黄铜球盘和15个1/2英寸(12.7mm)和3/8in (9.5mm)直径的钢球组成。圆球盘有一个特殊的8mm厚的硬化黄铜底板，在1092毫米的内半径，以提供3.2毫米的厚度在它的中心。底板安装在一个标准的全高度筛框框架内，并有扩展的边缘用于堆叠。
在使用中，一个100ml大小的样品被放置在球锅中，用30个钢球，在摇筛机中运行30分钟。重球盘松散堆叠(自由旋转)，有5个常规的8英寸筛网，筛板和盖子。活性炭样品的“硬度”是通过对地面样品的筛分来测定的。如果需要的话，可以从Gilson提供SS-30型滚珠、筛子、筛板和盖子。Est. Ship Wt.: 6lb (3kg)。
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).
