Pelletized Powder Mass Strength Test TEST EQUIPMENT TO DETERMINE THE MASS STRENGTH OF PELLETED CARBON BLACK AS PER ASTM D1937 State-of-the-art design Force measure by load cell Motorized plunger with position feedback of sample height Single supply: wide range mains 90 to 240 VAC Table model: 610 x 440 x 900 mm (W x D x H) 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 D1937-13 The PMST by HITEC Luxembourg is a small press with up to 500 N compression force. It is equipped with a load cell to hold a compression plunger. The plunger and load cell holder are mounted on a motor driven carriage with a travel range of 255 mm. The plunger immerges into a compression cylinder, which bottom has a removal slide door. The design allows compressing a powder under controlled conditions and to observe its flowabilty after such a compacting. • Motor controlled accurate load application • Linear carriage with load cell, stepper motor driven up to 30 mm/s and with position reading • Programmable controller with 5.7" display, 640x480 px • 4 robust push buttons for “dirty” operations • Anodized aluminum frame and fully dust proof stainless steel electronic cabinet • Software guided measurement sequence according to ASTM D1937 • Software guided load cell calibration • Compact table model – small footprint • AC mains supply only (no compressed air) Copyright © 2015 HITEC Luxembourg S.A.
