CATALYST CRUSHING and ABRASION TESTERS
As per ASTM D4058-  D4179- D6175- D7084

The crush strength represents the resistance of the solid to compression, a property of paramount importance not only for industrial catalysts, but also for ceramics, pharmaceutical tablets and many other solid materials. In the case of catalysts it is noteworthy that many plant shutdowns occur due to mechanical failure of the catalyst, not to its loss of activity. Therefore an accurate measurement of catalyst mechanical properties is mandatory.
 
 
      
  • This unit allows to make both single pellet and bulk measurements with the same instrument without any modification of its parts. It includes a digital display, providing the crush strength in Newton, and an analog output for a 30 mV recorder, where the shape of the crush peak can be observed. This instrument is a dynamometer of general use for compression measurements. As far as catalysts are concerned, the ASTM standard methods D4179 and D6175 are recommended. D4179 refers to tableted pellets. For bulk crush strength this unit can also run the new method D7084
 
 
 
 
 
  • This rotating cylinder abrasion tester is dedicated to determination of the abrasion resistance of a solid material, either in a granular or a pellet shape or as a coarse powder , whose size can vary in the range 0.85 –20 mm .
  • This rotating unit complies with ASTM D-4058 method .It allows to perform fast and reliable determination of the abrasion resistance of solid materials.
