The estimated capacity is the maximum capacity of the crusher given the input parameters, assuming an unobstructed and perfect flow of particles. This implies that the capacity may be overestimated in most real applications; there are a few explanations for this. First, the perfect chamber utilization of each crushing zone is unlikely.
