crusher squeezes rock between two surfaces, one of which opens and closes like
a jaw. Rock enters the jaw crusher from the top. Pieces of rock that are larger
than the opening at the bottom of the jaw lodge between the two metal plates of
the jaw. Jaw Crusher opening and closing action of the movable jaw against the fixed
jaw continues to reduce the size of lodged pieces of rock until the pieces are
small enough to fall through the opening at the bottom of the jaw. It has a
very powerful motion.
structure of jaw crusher contains the frame, eccentric shaft, big belt pulley,
flywheel, movable jaw, side guard plate, toggle plate, rear seat of toggle
plate, modulation gap screw, returning spring, fixed jaw plate and movable jaw
plate, etc, among which the toggle plate is used for safety. The working mode
of this series jaw crusher is pressing deviously.
crushing machine working theory is: The motor drives belt and belt wheel, the
eccentric shaft causes the movable jaw to move down and up, forward and
backward, the angle between toggle plate and movable jaw becomes bigger when
the movable jaw moves up, so that the movable jaw moves toward the fixed jaw,
and the materials are pressed, crushed, or cut, as a result, the aim of
crushing is accomplished.
