The 4″ x 5″ is a Laboratory Rock Crusher engineered for rapid reduction of hard and brittle materials. The 911MPCJC200D Jaw Crusher is designed for batch-wise and continuous pre-crushing of middle hard, hard brittle, and tough materials for the following fine …

The present work uses a Particle Replacement Model (PRM) embedded in the software EDEM® to model and simulate operation of a laboratory-scale jaw crusher. The PRM was calibrated using data from single particle slow compression tests, whereas simulations of the jaw crusher were validated on the basis of experiments, with very …

For the 1-in. screen below the roll crusher the capacity has no correction factor and the area needed is 32/2.1 = 15.2 sq ft. To handle the output from a 40 x 24 roll crusher the screen will have to be at least 24 in. wide. Perhaps it will be more effective to use one continuous screen of at least 20.1 + 15.2 = 35.3 sq ft.
