contact usbriefly contrast arrested vs choked crushing on a cone crusher. Choke feeding is important for cone crushers because it maintains a good particle shape by facilitating an inter-particle crushing action. Trickle feeding is not the best option because it increases the proportion of flaky material in the crusher product hindering its efficiency.

contact us2006-1-1 · Beam A1, failing by concrete crushing, is insensitive to changes in the concrete fracture energy. In contrast, the failure mode and peak load of beam B3, failing by plate debonding, are significantly affected by the magnitude of the concrete fracture energy. A low value of the concrete fracture energy (0.5G F) results in premature plate debonding.
