operating hours was 8 460 hours The 12 month average failure rate was failures per 1 000 hours and the 12 month average MTBF was 368 hours This data shows that the failure rate of impact crusher machines varies every month Keywords
·In this paper studies into the causes of fatigue cracks of a jaw crusher supporting structure are presented The problems appeared after short time of operation at a new crushing facility A large number of fatigue cracks with a high growth rate and bolt failures were observed in the crusher supporting structure Considering the high dynamic forces that occur
·To our knowledge this is the first quantitative study on actual and ideal HFC entry criteria as well as exclusion considerations although there has been a review of guideline recommendations for entry criteria 13 with more recent guidance by the Heart Failure Society of America HFSA 24 primary studies on the clinical characteristics of
Further by implementing ANOVA parameters such as the shape scale and time are evaluated to examine the failure rates of crusher and its components The data for these three parameters have been generated through Monte Carlo Simulation method A 23 factorial design is used for the failure rate analysis
·the failure in the point of view of determined factor and number 10 indicates that the biggest importance that must be attributed to the failure The critical components function of the components functional failure of compo nent failure mode and effect of component failure of the crusher under study is shown in Table 2 The severity
·The crusher jaw had therefore failed prematurely ASTM A 128 grade B 4 is a grade of austenitic man ganese steels that combines both high toughness and good wear resistant properties required for crusher jaws From the spectrometric analysis the elemental composition of the failed crusher jaw conforms to ASTM A 128 grade B 4
·Over the last few decades the demand for energy efficient mineral processing methods has continued The necessity to develop energy efficient technologies for the mineral industry will increase in the future considering the exhaustion of high quality resources and severe environmental limitations The subject of this study is crushing equipment It is a
