  • Rock Crushing Rule of Thumb Mineral Processing & Metallurgy

    The desired grizzly opening for an underground jaw crusher is equal to 80% of the gape of the crusher. Source: Jack de la Vergne; The maximum feed size for a jaw crusher should be about 85% of the gape. Source: Arthur Taggart; The combination of a jaw crusher and a scalping grizzly will have 15% more capacity than a stand-alone jaw crusher.

  • Capacities and performance characteristics of jaw crushers

    Although jaw crushers are extensively used for a variety of materials, their operational characteristics are not well understood. This lack of understanding makes selection of the proper machine difficult. Hersam (1923) proposed a method for calculating capacities using a Dodge-type jaw crusher.

These are not limited to the design features of the crusher. If the feed is blasted rock from a quarry, the size and method of handling the feed influence crusher selection. For instance, a power shovel is limited by the dimensions of the dipper in the maximum size of rock it can handle well. ISee more on 911metallurgist

When the swing jaw is rising, it is opening, at the top, during the first half of the stroke, and closing during the second half, whereas the bottom of the jaw is closing during the entire up-stroke. A reversal of this motion occurs during the downstroke of the eccentric.See more on 911metallurgist
  • Crusher Efficiency Calculations

    The specifications and manufactured limitations, rather than economy, generally govern the selection of crushers. To find the required areas of screen, the rate of feed of material as well as gradation of the feed must be known. The 1½-in. screen under the jaw crusher is the top deck—no deck correction factor will be necessary.
