catalyst crush strength apparatus

Apparatus for measuring the crush strength of solid ...

The crush strength may then be computed. A suitable sample of catalyst or adsorbent consists of many particles and contains particles having wide variations in crush strengths. It is therefore desirable to test many particles to obtain an average crush strength value representative of the sample. The subject invention permits such rapid testing.
