Jaw  Crusher (Improved  Jaw  Crusher)
    The machine frame and swing  jaw of the jaw crusher are cast as a whole with cast steel . Jaw Crushers work  in this way: The electromotor drives the eccentric shaft to move the swing  jaw up and down through  driving belts and a pulley. When the swing jaw moves  upward and  toward the fixed jaw, the angle between the toggle plate and the swing jaw becomes bigger,  the building stones are crushed due to  compressing and  chopping . When the swing  jaw moves downward , the angle between the toggle plate and the swing jaw becomes smaller,   the swing jaw moves away from the fixed jaw under the action of the spring tension rod, and the crushed stones are discharged from the bottom opening of the crushing cavity. As the electromotor rotates continuously and  the swing jaw of the crusher moves periodically for crushing and discharging the stones, the batch production of  products  will  be  achieved . 
    Jaw Crushers have features such as  high reduction ratio , simple structure, reliable operation and easy maintenance as well as lower operational cost. It is suitable for crushing  stones with different hardness and with feeding sizes of no more than 1000 mm and discharging  sizes of  no more than 250 mm( however, the specific feeding and discharging sizes  should be decided by the  stone hardness and by choosing crusher models .). 
    Improved  Jaw  Crusher: Optimizing the technical parameters of jaw  crusher in an all-round way. Eccentric shaft is made of forged steel , subjecting to processing such as heat treatment  and precision grinding and so on . Heavy-duty belt pulley and flywheel are installed  in a large size jaw  crusher , possessing big inertial force  and preventing clogs in the machine ,and increasing the  product output. The belt pulley and  flywheel  are  assembled  through expansion bushings , easy to be dismantled . The jaw plates are cast of quality  alloy  with high manganese content , improving the  abrasion  resistance  of  jaw  plates.  National patent has been applied for the improved  jaw  crusher.
