美國W.S.Tyler Gilson強度測試篩

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，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).
