The main part of the jaw crusher

Frame is opening up and down the walls of the rigid frame, used for supporting the eccentric shaft and bear the crawler type mobile crusher counterforce of crushing material, requires enough strength and stiffness, cast steel is commonly used in the whole casting, minicomputer can also be used high quality cast iron instead of cast steel. The anterior wall of the fixed jaw jaw is bed frame, movable jaw jaw bed hanging on the week, should have sufficient strength and rigidity, to inherit the fragmentation reaction, thus mostly cast steel or cast iron pieces.
Jaw Crusher machine with a compound pendulum mainly consists of the following major components of
they are: frame, a movable jaw, eccentric axis, gear, elbow, elbow board seat, bearings and tie rods and tie rod spring. The equipment of main work part is two block jaw Board,a is fixed mobile impact crushing plant  we often called set jaw, the e Board vertical (or top slightly decumbent) fixed in body Qian wall Shang, another a is activities jaw Board (moving jaw), the e board design of location is tilt of.

Dang broken machine started, eccentric axis rotating will will with of rotating, at equipment of moving portable crushing plants for sale  each points of movement track is by hanging points of Circle line , then gradually down movement into oval, moving e each points of movement track rendering out more to lower, oval more partial, calcite crusher until lower and thrust Board connection points track for arc line Shi, each points of movement track completed a work cycle.
