Test equipment to determine the mass strength of pelleted carbon black as per ASTM D1937.

The test method ASTM D1937 "… is designed to determine the force required to pack a cylindrical column with pelleted carbon black. The results of this test are believed to relate to the ability of the carbon black to flow in bulk handling systems." … "Mass strength gives an indication of the flowability in bulk handling. It is affected by pellet properties such as hardness, size, shape, and especially fines content."** Excerpts from chapter 1 resp. 4, of ASTM D1937-18
