the main components of jaw crusher 1. Rack The rack is the opening framefor supporting the eccentric shaft and bear fragmentation reaction of materials, require sufficient strength and stiffness, which is often cast as a whole cast, minimal machine can also be used iron steel instead of high-quality cast. Sub-frame cast mainframe. and then bolt firmly linked into the overall, it is a complex casting process. 2. jaw plate and check plate Both fixed jaw plate and movable jaw plate are consist of jaw plate and jaw bed. They should have sufficient strength and rigidity to withstand fragmentation reactions, which are mostly cast steel or cast iron. 3.

Jaw Crusher transmission parts Eccentric shaft is crusher machine spindle, bent by the enormous torque, cast high carbon steel. Eccentric part required fine finishing, heat treatment. one end of eccentric shaft is mounted pulley, the other end with the flywheel installed. 4. conditioning Conditioning installations have wedge, plate type and the hydraulic type, and other kinds, generally is wedge. wedge is formed by the two, the former wedge can move easily withstand push back plate; wedge after the wedge for the adjustment can be up and down Mobile, the screw force it to move up or down to adjust the size of the discharge port. 5. Flywheel The flywheel is cast iron or cast steel. the minicomputer often has integral flywheel. When flywheel manufacture, installation, pay attention to static balance. 6. Jaw Crusher Lubrication Device Eccentric shaft bearing lubrication cycle is usually concentrated. Spindle and thrust plate bearing surface generally use the grease gun oil to the oil by hand. the swing angle of fixed jaw plate is small, so that lubrication between the spindle and bearing is difficulty. open a number of oil groove, open a ring at middle part to connecte the oil groove. and then forced into the dry butter oil pump lubrication.
