Simheuristic-based decision support system for efficiency

Sep 01, 2020 The efficiency of each cone crusher depends of the cavity level. That is, cone crushers that operate at low cavity are less efficient than crushers operating at super chocked or full cavity. Therefore, this behavior must be simulated. Section 4 treats this issue and Section 5 details the simulator developed for evaluating the crushing circuit; 10.

Sep 15, 2014 Good component efficiency and part performance pre-evaluation is essential to a solid design. The aggregate production requires the consideration of several crushers, feeders and screens. This is not intended to be a typical situation, though it does involve common crusher and screen units often used in aggregate plants.
