·The reduction ratio is driven by the Crusher Close Side Setting The actual minimum safe closed side setting of a crusher will vary somewhat for any given crushing machine depending upon the character of the material the amount of fines in the feed and whether the crusher is being operated under choke feed or regulated feed conditions It is
Crusher types and their ratios Jaw Crushers Reduction ratio 6 1 Jaw crushers use pressure to break up very hard flaky and slabby rocks by passing them between a moving surface and a stationary one They are generally used for primary crushing but also provide great results with secondary crushing
·Jaw crusher movement is guided by pivoting one end of the swinging jaw and an eccentric motion located at the opposite end [4] The size of a jaw crusher is designated by the rectangular or square opening at the top of the jaws For instance a 22 x 30 jaw crusher has an opening of 22" by 30" a 46 x 46 jaw crusher has a opening of 46" square
·used crushers are of three types namely Cone crusher Jaw crusher and Impact crusher The first stage of size reduction of hard and large lumps of run of mine ROM ore is to crush and reduce their size Large scale crushing operations are generally performed by mechanically operated equipment like jaw crushers gyratory crusher and roll crushers
·R r = Crusher Reduction Ratio = 8 S = Set Size = 4 G = R r x S That is G = 8 x 4 G = 32 Therefore the gape size is Read more How to Calculate and Solve for Capacity of Jaw Crusher Mineral Processing Calculating the Set Size when the Crusher Reduction Ratio and the Gape Size are Given
·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
·As the equation for calculating the efficiency of a jaw crusher is a six variable equation set the results visualization represents no easy task It was found that the configuration of the optimum jaw crusher is not constrained by the material but this optimum will give a different total power efficiency value η Power Total depending on
·Tips to maximize crushing efficiency Pit Quarry Pit May 13 2019 Additionally jaw crusher feed should be prescreened using a grizzly screen prior to crushing to remove material finer than the closedside setting Setting jaw crushers Ideally the reduction ratio of a jaw crusher should be 6to1 There are different ways to calculate reduction ratio but the best way is
