— The crushing rate refers to the proportion of crushed proppant under a certain pressure. It is typically calculated by dividing the mass of the crushed proppant smaller than a certain size by the total mass of the proppant used. However, using screens to separate crushed micro-proppants is impractical due to the too-small particle size.
