<p>This 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.</p> <p>The angle between toggle plate and movable jaw becomes smaller when the movable jaw moves down, the movable jaw leaves the fixed jaw because of the function of drag link and spring, here the crushed materials are discharged from the bottom hole of crushing chamber. Along with the continuous turning of motor, the movable jaw of crusher moves periodically to crush and discharge materials, so that the mass production is obtained.</p> <p>Our jaw <a href="http://www.hx-crushers.com/p3.html">stone crusher</a>s are famous for their durable parts, extensive application, innovative design and fine-processed parts, low price.
