Connecting rod of crank-link mechanism drives directamente by eccentric shaft, the lower end of movable jaw connect with the toggle plate and support to the back wall of the rack. When eccentric rotates, the motion curve of every point in jaw is movable circumference of the pendant point (radius equals to eccentricity) down to ellipse, the lower, the become gradually more slanting of ellipse, till the bottom becomes arc with the track of toggle plate junction point. As the motion curve of points in the movable jaw is complex, the machine is called as complex pendulum jaw crusher. Due to the relatively low productivity of the jaw crusher, most large-scale dressing plants generally adopt the gyratory crusher as in the first-stage coarse crushing. Besides, the reduction ratio of the jaw crusher is smaller than that of the gyratory crusher. The reduction ratio of a gyratory is able to reach 6 to 9.5, on rare occasion it can reach 13.5.
But jaw crusher is mostly applied in the first-stage coarse crushing (cone crusher) en la pequena concentrators as well as quarries. If measured from the feeding, discharging coexistence and productivity and these two types of machine can meet the requirement, and then we should make a decision from many aspects as the secondary, tertiary crushers used in the process flow, investment and infrastructural expenditure. Henan Hongxing Mining Machinery Co., LTD is a large professional manufacturer of mining machinery. It researches and developments the advanced level jaw crusher by absorbing domestic and foreign advanced technology and combining with market trends. This series jaw crusher can greatly reduces the production costs and air pollution. Now the Hongxing brand jaw crusher is warmly welcomed in the market which is thought as the top one crushing equipment and the most valuable product.
