Crushers-an overview | sciencedirect topics

The cone crusher is a modified gyratory crusher. the essential difference is that the shorter spindle of the cone crusher is not suspended, as in the gyratory, but is supported in a curved, universal bearing below the gyratory head or cone (figure 8.2). power is transmitted from the source to the countershaft to a v-belt or direct drive.

analysis technology nsk bearings support mining machinery for the challenging task of raising efficiency and productivity of operations under harsh environments. jaw crusher work material is crushed between two opposing jaw plates. one plate opens and shuts, crushing raw material against the stationary jaw plate. cone crusher

cone crusher’s troubleshooting and maintenance measure. cone crusher often appear the gears unwearable, broken teeth; reduction in the fuel tank, oil level decreased significantly; oil pressure lower than 0.05 mpa; water in oil; seal drainage oil, oil temperature does not rise; at the same time increasing the hydraulic oil also increased; the filter pressure is too large; oil temperature exceeds 60 ℃, but the oil does not rise; lubrication oil qualitative difference; crusher

Bearing failure: causes and cures

Increase bearing vibration (noise]. severe brinell marks can cause premature fatigue failure. any static overload or severe impact can cause brinelling. examples include: using hammers to remove or install bearings, dropping or striking assembled equipment, and a bearing onto a shaft by applying force to the outer ring. install bearings by applying

1. the oil temperature is too high. 2. oil temperature and pressure rise. 3.oil pressure is low after oil pump is started. 4.oil contain lots of fine mud and impurities. 5.there is water in the oil. 6.the vibration of cone crusher is too strong. 7.

a basic understanding of bearing failures and failure analy sis. with the knowledge presented in this publication, it is pos sible to assess simple failure situations and start the right analysis. however, the information is not sufficient to do in-depth bearing failure analysis and does not compensate for experience neces - sary in this domain.
