how jaw crusher to calculate the material through feed opening?

How jaw crusher feed opening through to conversion material ? In fact, on the crusher model problem , we are on a topic already mentioned , it is how to distinguish ? This issue, we do a review , mainly from the naming of jaw crusher , the size to be divided . PEX is generally thin broken , PE is coarse broken, such as the common and common models : PEX-250 * 1000, PEX-300 * 1300. Above thin broken , broken in the domestic crude common and common models : PE-600 * 900, PE-800 * 1060.
Above only a few examples , to distinguish fine coarse broken broken , mainly because the letter naming , and crushing ratio is based on the model and size for division. So how through the feed opening to conversion of the obtained materials , this is a formula , generally you can simply translated.
In this way can be used to get to the inlet size of discharge opening width
For large PEX formula : L = (1.25 ~ 1.5) B
For small PEX formula : L = (1.5 ~ 1.6) B
Feed opening width B determines the maximum crusher feed size Dmax size. General admission Dmax = (0.75 ~ 0.85) B. In the country , through this formula has two, one simple pendulum A complex pendulum :
Jane Swing : Dmax = 0.75B
Complex Tilting : Dmax = 0.85B
By this formula , you can get the width of the discharge opening , can roughly calculate how much material will be discharged .
