摘要：反击式破碎机是一种连续的非机械式破碎机.它将打击，反击，离心冲击，剪切，研磨等破碎原理有机结合在一起，是其能量和破碎空腔得到充分有效的利用，破碎效率高，出料细而均匀，易损零件少，文护保养方便，能耗低.生产的产品粒型好且呈棱角，针片状少，粒度连续且粉末少。21305
反击式破碎机的冲击破碎能力大，越来越广泛的应用在建材，冶金，化工，选矿等行业.反击式破碎机特别适合于破碎中等硬度的脆性材料.它可用来破碎：石灰石，煤，砂岩，水泥熟料，铁矿石，钼矿石等物料的粗碎.中碎，细碎，用于磨前细碎时可大幅度降低磨机的入磨物料粒度，起到以破代磨的功效。
反击式破碎机具有独特的工作机理及结构设计特点。在使用性能特点上，反击式破碎机与锤式破碎机相比具有明显的技术优势出料粒度均匀，出料呈立方体形状，细粉料和粉尘含量低，特别适合立磨的运行。运行成本低，投资成本低反击式破碎机整机总重较锤式破碎机轻，外形尺寸小，动静荷载值低，可以有效地降低土建费用。同时，所需要的电机功率低，可以有效降低设备耗电量，降低设备运行成本。反击式破碎机易损件使用寿命长，长期运行成本低。

PF-1318 impact crusher body chassis design
ABSTRACT:Crusher is a continuous non-mechanical crusher. Would hit back, centrifugal impact, shearing, grinding, crushing principle organic combination of its energy and crushing cavity to be fully effective use, broken high efficiency, thin and uniform discharge, less wearing parts, easy maintenance, low energy consumption. products and showed good grain edges, less flakiness, continuous particle size and less powder.
Impact crusher crushing capacity, more widely used in building materials, metallurgy, chemical, mineral processing and other industries crusher is particularly suitable for crushing medium hardness of brittle materials which can be used to crush: limestone, coal, coarse crushed sandstone, cement clinker, iron ore, molybdenum ore and other materials. middle crushing, fine crushing, can greatly reduce the time for pre-crushing mill into the grinding mill particle size, play to break instead of grinding effect.
Crusher has a unique working mechanism and structural design features. In the use of performance characteristics, impact crusher and hammer crusher has obvious technical advantages compared to a uniform particle size, the material showed a cube shape, fine materials and low dust content, especially for vertical mill operation. Low running costs, low investment costs crusher machine compared to the total weight of the hammer crusher is light, small size, low static and dynamic load values, can effectively reduce construction costs. Meanwhile, the required motor power is low, the device can reduce the power consumption and reduces operating costs. Crusher wear parts and long service life, low long-term operating costs.
