Moist, spherical zeolite 4A granules were tested by compression at a constant loading velocity until primary breakage, and were also rectilinearly accelerated and impacted to achieve breakage using a pneumatic canon. The compressive breakage force and the impact breakage velocity distributions were determined. The results obtained by compression and impact tests were evaluated using the model from...
Impact tests against a hardened steel plate have been carried out to obtain the coefficient of restitution of three types of spherical granules. The dominant elastic γ-Al2O3, the elastic-plastic zeolite 4A and the dominant plastic sodium benzoate have been chosen as granule samples. An electromagnetic canon has been constructed to accelerate the granules and to measure the normal coefficient of restitution...
