SSA-39 美国Gilson球盘硬度实验 泰勒筛强度测试盘 硬度测试盘

球盘式硬度试验方法已被广泛应用于对粒状活性碳进行降解性的测定。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(12.7 mm)和3 / 8in(9.5 mm)直径的钢球组成。圆球盘有一个特殊的8mm厚硬黄铜底板，在1092mm内半径，在其中心的厚度为3.2毫米。底板安装在标准的全高度筛网框架内，并有扩展的边缘用于堆叠。

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).
