  • Crusher Wikipedia

    A jaw or toggle crusher consists of a set of vertical jaws, one jaw is kept stationary and is called a fixed jaw while the other jaw called a swing jaw, moves back and forth relative to it, by a cam or pitman mechanism, acting like a class II lever or a nutcracker. The volume or cavity between the two

    Dual drive arrangements use a separate electric motor and Vbelt drive for each roll, resulting in quiet operation and minimal vibration. For single drive arrangements, power is transferred to opposing rolls by an interstage Vbelt drive. Double Roll Crushers can be equipped with an automatic lubriion system. Product size

  • a fracture toughness based model for the prediction of VTechWorks

    The models allow for the selection of a jaw crusher based on the nature of the rock being broken and the average amount of size reduction done on the feed material. The models can also be used to optimize feed and operational settings, as well to determine the product size produced for a given rock and reduction ratio.
