Breaking Down the Basics: Jaw Crusher Capacity Calculation: The jaw crusher is one of the most commonly used primary crushers in the mining, quarrying, and construction industries. Its capacity, or the ability to crush material, is often cited as a key factor in determining its performance. The capacity of a jaw crusher is typically measured in ...
Reduction of data from one type or size of jaw crusher into the equivalent performance of another crusher has been accomplished by ratios of all of the various equation factors involved. The individual u Fig. 3-Dodge-type jaw crusher showing relative swing jaw motion at feed and discharge ends.
The estimated capacity is the maximum capacity of the crusher given the input parameters, assuming an unobstructed and perfect flow of particles. This implies …
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 possible, when all conditions are favourable, to …
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 image above represents capacity of jaw crusher. To calculate capacity of jaw crusher, three essential parameters are needed and these parameters are Gape Size (G), Width of Crusher (W) and Closed Single Setting of Jaw Crushers (CSS). The formula for calculating capacity of jaw crusher: C JC = G.W / CSS. Where: C JC …
J r = Jaw Crusher Rating = 32 W = Width of Crusher = 2. G = J r / W That is, G = 32 / 2 G = 16. Therefore, the gape size is 16.
