顎式破碎機(改進型顎式破碎機)：
　　顎式破碎機，機架、動顎采用整體鑄鋼結構。通過電動機驅動皮帶和皮帶輪，通過偏心軸使動顎上下運動，當動顎上升時肘板與動顎間夾角變大，從而推動動顎板向固定顎板接近，使其石料被壓碎或劈碎，達到破碎的目的；當動顎下行時，肘板與動顎夾角變小，動顎板在拉桿、彈簧的作用下，離開固定顎板，此時已破碎石料從破碎腔下口排出。隨著電動機連續(xù)轉動而破碎機動顎作周期運動壓碎和排泄石料，實現(xiàn)批量生產(chǎn)。
　　該機具有破碎比大、結構簡單、工作可靠、維修方便和運營成本低等特點。適用于各種硬度、進料粒度≤1000mm、出料粒度≤250mm石料的破碎（具體進出料粒度要根據(jù)石料硬度并通過選擇機型來確定）。
　　改進型顎式破碎機，全面優(yōu)化顎式破碎機的技術參數(shù)。偏心軸采用鍛打鋼并經(jīng)熱處理、精磨等加工；大型顎式破碎機采用重型皮飛輪、慣性力大、避免石料卡機、提高產(chǎn)量；皮飛輪采用脹套裝配、便于拆卸；齒板采用優(yōu)質高錳合金材料鑄造、增強耐磨性。已申報國家專利。

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.
