Design and function

Jaw crusher is mainly used for primary crushing.
It is made up of frame, eccentric shaft, grooved wheel, and flywheel, moving jaw, side guard plate, and toggle plate, toggle backseat, adjusting screw, returning spring, fixed jaw plate and moving jaw plate. Toggle plate is of safety function.
In jaw crusher the material is being sandwiched between the two jaws. The jaw moves to the maximum position of the jaw plate, i.e., the movable the jaw plate leaves the fixed jaw plate to the furthest position. Then the material falls into the crushing chamber, the movable jaw plate moves gradually to the fixed jaw plate, thus material is squeezed into several small pieces. Due to gravity, the crushed material will fall, and those small enough will be discharged by the crusher. And the bigger sizes will fall to the bottom of jaw crusher chamber, and will be crushed again with newly fed raw materials.
