Description

The versatile catalyst crushing strength tester can be configured for both single-grain and bulk crushing strength measurements. The unit is based on an automated press equipped with a high-precision force sensor to ensure accurate and repeatable results.

Single-Grain Crushing Strength (GCS) – ASTM D4179 & ASTM D6175
In single-grain mode, the tester evaluates individual catalyst pellets or radially oriented extrudates. Each grain is positioned on a transducer anvil and crushed by a motorized piston. The force applied at the moment of rupture is detected by the sensor and recorded by the control software. Results are automatically processed and presented in a detailed analytical report. The system includes multiple standardized hammer-anvil and hammer-holding sets made of stainless steel and fully complies with ASTM D4179 and D6175 standards.

Bulk Crushing Strength (BCS) – ASTM D7084 & SMS-1471
In bulk mode, the instrument measures the crushing resistance of a catalyst bed composed of grains up to 6 mm in size. This configuration is designed to assess the mechanical strength of catalyst batches under realistic loading conditions and complies with ASTM D7084-18 and SMS-1471 standards.
