reduction through the crusher and the end product shape Closed side setting CSS The closed side setting has a significant effect on the product gradation capacity and power draw of an MP Series cone crusher The closed side setting is measured from the bottom of the mantle to the bottom of the bowl liner at their closest point during the
The horizontal axes represent cmmdative percentages passing corresponding screen openings If we wish to check the product to be expected from a crusher set at some predetermined discharge opening we first refer to the table showing the approximate percentage of product which will pass an opening equivalent to the crusher setting
A jaw crusher usually wears more manganese steel per crushed tonne than a gyratory crusher Feeding fines into the crusher may increase peak stress loads because of packing ie material being compacted as far as it compacts This is enhanced by moisture which again is highest in the fines and quite common in underground mines
crusher Whenever a jaw crusher is off and at rest stopped it will remain in the open position at its open side setting OSS However the adjustment of your crusher is performed at its closed side setting CSS OSS is measured while the crusher is stopped CSS is calculated by deducting a certain amount the average stroke from the OSS
More compact More energy efficient More powerful Operation principle Fines are screened out by means of an integrated grizzly and bypassed through the crusher housing The coarse particles are transferred into the crushing chamber The rotation of the drive motor is transmitted via V belt drive to the eccentric shaft of the roll This is
It was concluded from the experiments that among process parameters RPM has a more prominent effect on generation of fines compared to feed rate feed size and gap setting Among coal properties volatile matter ash content and fixed carbon have significant effect followed by moisture content

The model depends on the feed gradation and crusher setting The optimization routine will therefore be able to find the best machine parameter settings for the plant The optimum setting will maximize the gross profit and produce products with the required quality Since a smaller CSS will generate more fines the crusher was kept as

Fines for example 0 4 mm should be screened out before the material is fed to the crusher as the fines may cause packing this is a force overload and can be seen as adjustment ring movement There are differences within different product ranges and Nordberg GP Secondary cone crushers for example can handle a certain amount of fines in

For example If the following process requires 100% less than 80 mm without a high quantity of fines the crusher can produce 90% less than 80 mm After screening out the 0 80 mm fraction the oversize that is more than 80 mm material is
closed side setting position The maximum feed size in GP cone is the same as closed side feed opening Maximum feed sizes are also stated in chamber configuration tables later in the guide Closed side setting CSS The closed side setting defines the reduction ratio in GP cone crusher and has significant bearing on product gradation capacity
