SSA-39 美國Gilson球盤硬度實驗 泰勒篩強度測試盤 硬度測試盤

球盤式硬度試驗方法已被廣泛應(yīng)用于對粒狀活性碳進行降解性的測定。ssa - 39模型由一個特殊的8in(203mm)直徑黃銅球盤和15個1 / 2英寸(12.7 mm)和3 / 8in(9.5 mm)直徑的鋼球組成。圓球盤有一個特殊的8mm厚硬黃銅底板，在1092mm內(nèi)半徑，在其中心的厚度為3.2毫米。底板安裝在標準的全高度篩網(wǎng)框架內(nèi)，并有擴展的邊緣用于堆疊。

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).
