Structure of Small Jaw Crushers

First we look at a rack of small jaw crusher. Rack jaw crusher is the opening of the upper and lower walls of the rigid frame, used to support the eccentric shaft and bear fragmentation reaction of materials. Under normal circumstances, the rack should have sufficient strength and stiffness, with the whole cast steel. Small jaw crusher frame can also be used in place of high-quality cast iron. Large jaw crusher frame required segmented cast, and then bolt firmly linked into a whole, the casting process is complex.

Followed by a small jaw crusher jaw plate and side guard. Fixed jaw and a movable jaw by jaw bed and jaw plates, jaw is working part, fixed jaw and wedge bolts bed. Small jaw crusher jaw jaw fixed bed frame is anterior, moving jaw jaw hanging in the week on the bed, have sufficient strength and rigidity to withstand the crushing counter- force, so it is mostly composed of steel or cast iron.

The third is a small transmission parts jaw crusher. The eccentric shaft spindle small jaw crusher, by a huge bend torque, generally made ​​of high carbon steel. Eccentric parts should be finishing, heat treatment, bearing liner with Babbitt pouring.

The fourth is to adjust the device small jaw crusher.

Small jaw crusher discharge port regulation is thrust plate bearing shims between the rack to realize how much change after use.

Finally, we look at a lubricating device small jaw crusher. The eccentric shaft bearings are usually centralized lubrication cycle. Spindle and thrust plate support surface generally use the grease gun oil to the oil by hand. Movable jaw swing angle is very small, so that lubrication difficulties, often in the bottom of the opening number of the axial bearing oil groove between the spindle and bearing, in the middle to open a ring connected to the tank to make it, and then forced to inject dry butter oil pump lubrication.
