文档介绍：Jaw Crusher 颚式破碎机 Usage and Application 用途及适用范围 颚式破碎机广泛应用于矿山、建材、化工、冶金等行业, 可对抗压强度不大于320MPa的各种矿石、岩石等物料进行粗、中碎作业。工作原理 颚式破碎机由电动机驱动皮带和皮带轮,通过偏心轴使动颚上下运动,当动颚下行时,定颚与动颚间夹角变小,物料被压碎达到破碎目的;当动颚上升时,定颚和动颚间夹角变大, 动颚板在拉杆、弹簧的作用下离开定颚板,此时已破碎物料从破碎腔下口排出。性能特点 1. 结构简单,使用维护方便; 2. 破碎比大,产品粒度均匀; 3. 性能稳定,使用成本低; 4. 噪音低,粉尘少。 The jaw crusher is widely used in mining, building materials, chemical industry, metallurgy and so on. It is suitable for primary and secondary crushing all kinds of minerals and rocks pressive strength less than 320 MPa. Working Principle The belt and belt pulley are driven by a motor, and the movable jaw moves up and down via eccentric shaft. The angle between fixed jaw and movable jaw es smaller when the moving jaw runs down, then the materials are crushed into pieces. It es bigger when the movable jaw runs up. The movable jaw plate leaves the fixed jaw plate under the action of tension rod and spring , then the end e out from the crushing cavity. Working Principle 1. Simple structure, convenient maintenance; 2. High crushing ratio, even output granularity; 3. High reliability, low investment; 4. Low noise, less dust. >>E-mail: >>Website: >>Тel: 400-700-8862 项目 Item Feed Opening Size(mm) Capacity (t/h) Weight (t) Overall Dimension (mm) Motor Power (kw) Max.
