Actual Operation And Wear Theory Of Jaw Crusher

failure rate analysis of jaw crusher: a case study,the jaw crusher. crushing is the first stage of size reduction of mined rocks. primary crushers are heavy-duty machines, used to reduce the run-of-mine (rom) ore down to a size suitable for easy handling. a line diagram of a double toggle jaw crusher and its main components is shown in figure 2. the jaws are set at an angle to each other..failure analysis of jaw crusher and its components using,from figure, it signifies that the fitted value of jaw crusher and its components have been compared with an actual value. the r 2 of jaw plate has best-fitted component of the jaw crusher. from the observation of variance, it is concluded that the variance is zero for the jaw crusher and its components as shown in table 8. variance value zero.
