6 Cone Crusher Material is fed into the crusher cavity and processed by the eccentric rotating action of the inner cone against the outer cone. Product can be reduced to a diameter ranging from 50mm to 100mm. Quarrying and Mining Process Dragline Dumper Truck Stockpile Dump Hopper Ground Conveyor Primary Jaw Crusher Back Hoe Tractor Double Decker Screen Vibrating Feeder Screen Stockpile Stockpile Cone Crusher Secondary Screening Jaw Crusher Work material is crushed between two opposing jaw plates. One plate opens and shuts, crushing raw material against the stationary jaw plate. PRIMARY...

Quarrying and Mining Industries 7 Surge Hopper Double Decker Screen Double Decker Screens Cone Crushers Impactor Storage Bins Sales Delivery Impact Crusher As indicated by its name, this machine crushes ore through impact and steadily reduces the size of the crushed particles through sharp, repeated impact with a rapidly spinning hammer, steel plate or stick. Vibrating Screen The vibrating screen consists of a case with a shaft and housing installed inside, with springs supporting the case. The swing and rotation of the shaft is produced by the attached unbalanced weight, which generates...

12 Mobile Plant Bearings HPS™ Spherical Roller Bearings HPS series bearings are double-row self-aligning spherical roller bearings capable of carrying heavy radial loads with moderate axial loads in either direction. The spherical profile of the rollers, the inner ring raceway and the outer ring raceway, enable a self-aligning function that allows full capacity loading. The HPS series offers standard-size (steel-cage) and large size (brass cage) bearings with longer operating life and higher limiting speeds than conventional bearings. EM/EW Series EM and EW bearings are cylindrical roller...

Quarrying and Mining Industries 13 Hi-TF Bearings Hi-TF bearings were developed with innovative materials and heat treatment technology for increased durability under harsh conditions. They combine long service life with good resistance to wear and seizure even under contaminated lubrication to achieve outstanding cost performance. TM Series Sealed Deep Groove Ball Bearings TM series bearings are deep groove ball bearings capable of carrying radial and axial loads in either direction. The low frictional torque of these bearings enables use in highspeed applications and feature low noise and...
