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.Machine efficiency and man power utilization on production ...work efficiently, but in some circumstances machines can be less productive due to improper preventive maintenance. Preventive maintenance is a key factor that keeps the machine running efficiently through the production process. The maintenance activity on machines needs extra attention by the management along with the responsible personnel toFDK-Type Algorithms with No Backprojection Weight for ...Note that the integration in second formula in is over β and therefore it is a fan-beam backprojection while the integration in first HFDKW formula being over θ results in a parallel-beam backprojection.The first HFDKW formula can be modified to include redundancy weight for partial scan data as given by You and Zeng [] ().The conventional FDK formula involves a weighted .14 Cone Crusher Common Problems And How To Fix Them | M&CCone crusher has high crushing ratio, high efficiency, low energy consumption, uniform product size, suitable for medium crushing and fine crushing of various ores and rocks.
