41、用来破碎的设备都是中小型的，也是近几年来也慢慢由于各个行业的生产能力逐渐增长，这种成产能力已经跟不上生产需要的，许多单位以及厂家对大型破碎设备，矿石设备的呼声越来越强烈。逐渐大型颚式破碎机（大型鄂式破碎机）也就应运而生了。鄂式破碎机简称鄂破，该系列产品具有破碎比大、产品粒度均匀、结构简单、工作可靠、维修简便、运营费用经济等特点。鄂破机(颚破机)广泛运用于矿山、冶炼、建材、公路、铁路、水利和化学工业等众多部门，破碎抗压强度不超过320兆帕的各种物料。 在矿山设备中，大型的颚式破碎机，反击式破碎机的生产能力是显而易见的，这种高能耗，高矿石吞吐量的破碎机一般都用在大型矿石，选煤厂等行业的破碎，目前的
42、大型颚破9001200的大型破在河南没有几家能够生产。该型鄂式破碎机是我公司的主打产品之一，尤其在设计和生产大型鄂式破碎机不论从技术工艺方面来讲，还是从生产能力方面来讲，在国内外已处于绝对领先水平。该机主要用于各种矿石与大块物料的中等粒度破碎，可破碎抗压强度不大于320Mpa的物料，分粗破和细破两种。该系列产品规格齐全，其给料粒度为125mm750mm,是初级破碎首选设备。鄂式破碎机(鄂破)广泛运用于矿山、冶金、建材、公路、铁路、水利和化等行业，它所应用的范围非常的广泛， 鄂式破碎机工作时候，动颚上端直接悬挂在偏心轴上，作为曲柄连杆机构的连杆，由偏心轴的偏心直接驱动，动颚的下端铰连着推力板支撑
43、到机架的后壁上。当偏心轴旋转时，动颚上各点的运动轨迹是由悬挂点的圆周线(半径等于偏心距)，逐渐向下变成椭圆形，越向下部，椭圆形越偏，直到下部与推力板连接点轨迹为圆弧线。由于这种机械中动颚上各点的运动轨迹比较复杂，故称为复杂摆动式颚式破碎机。复摆式颚式破碎机与简摆式相比较，其优点是：质量较轻，构件较少，结构更紧凑，破碎腔内充满程度较好，所装物料块受到均匀破碎，加以动颚下端强制性推出成品卸料，故生产率较高，比同规格的简摆颚式破碎机的生产率高出20-30%；物料块在动颚下部有较大的上下翻滚运动，容易呈立方体的形状卸出，减少了像简摆式产品中那样的片状成分，产品质量较好。鄂式破碎机的结构主要有机架、偏心
44、轴、大皮带轮、飞轮、动鄂、侧护板、肘板、肘板后座、调隙螺杆、复位弹簧、固定鄂板与活动鄂板等组成，其中肘板还起到保险作用。该系列鄂式破碎机破碎方式为曲动挤压型，电动机驱动皮带和皮带轮，通过偏心轴使动鄂上下运动，当动鄂上升时肘板和动鄂间夹角变大，从而推动动鄂板向定鄂板接近，与此同时物料被挤压、搓、碾等多重破碎；当动鄂下行时，肘板和动鄂间夹角变小，动鄂板在拉杆、弹簧的作用下离开定鄂板，此时已破碎物料从破碎腔下口排出，随着电动机连续转动破碎机动鄂作周期性的压碎和排料，实现批量生产。颚式破碎机的破碎腔是有固定的颚板和活动的颚板构成，固定颚和活动颚都衬有锰钢制成的破碎板，破碎板用螺栓固定在颚板上，为了提高
45、破碎效果，两破碎板的表面都带有纵向的波纹，而且凸凹相对，这样，对矿石除有压碎作用外，还有弯曲和剪切的作用。破碎机的工作腔的两侧壁上也装有锰钢衬板，由于破碎板的磨损是不均匀的，其下部磨损较大，为此，往往把破碎板制成上下对称的，以便下部磨损后，将其导致而重复使用，大型鄂式破碎机的破碎板是由许多块儿组合而成，各个都可以互换的，这样可以延长破碎板的使用期限。为了使破碎板与颚板紧密贴合，其间须衬有由可塑性材料制成的衬板，衬垫用锌合金或塑性大的铝板制成，因为贴合不紧密会造成很大的局部过符合，是破碎板损坏，紧固螺栓拉断，甚至还会造成动颚的破裂。活动颚板的摆动是借曲柄双摇杆机构来实现的，曲柄双摇杆机构由偏心轴
46、连杆，前推力板，和后推力板组成，偏心轴装在机架侧壁上的主轴承中，连杆（上连杆头）则装在偏心轴的偏心部分上，前后推力板的一端支撑在下连杆头两侧凹槽中的肘板座上，前推力板的另一端支撑在动颚后壁下端的肘板座上，而后推力板的另一端则支撑在机架后壁的肘板上，当偏心轴通过三角皮带轮从电动机获得旋转动力后，就使连杆产生上下运动，连杆的上下运动又带动推力板运动，由于推力板不断改变倾斜角度，因而使动颚绕心轴摆动，连杆向上运动时进行破碎矿石，当连杆位于下部最低位置时候，推力板与水平线所成的倾斜角度为十度或十二度。鄂式破碎机运行环境:在将巨大石块破碎成小石块的过程中，第一道破碎机通常称为“主”破碎机。历史最长，也
47、最坚固的破碎机是鄂式破碎机。为鄂式破碎机喂料时，物料从顶部入口倒入含有鄂齿的破碎室。鄂齿以巨大力量将物料顶向室壁，将之破碎成更小的石块。支持鄂齿运动的是一根偏心轴，此轴贯穿机身构架。偏心运动通常由固定在轴两端的飞轮所产生。飞轮和偏心支持轴承经常采用球面滚子轴承，轴承的工作环境极为苛刻。轴承必须承受巨大的冲击载荷，磨蚀性污水和高温。尽管此工作环境极为苛刻，鄂式破碎机仍需非常可靠地工作，这是保证生产效率的关键一环。鄂式破碎机性能特点:1.破碎腔深而且无死区，提高了进料能力与产量；2.其破碎比大，产品粒度均匀；3.垫片式排料口调整装置，可靠方便，调节范围大，增加了设备的灵活性；4.润滑系统安全可靠，
48、部件更换方便，保养工作量小；5.结构简单，工作可靠，运营费用低。6.设备节能：单机节能15%30%，系统节能一倍以上；7.排料口调整范围大，可满足不同用户的要求；8.噪音低，粉尘少鄂式破碎机用途和使用范围：1、该系列鄂式破碎机（鄂破）主要用于冶金、矿山、化工、水泥、建筑、耐火材料及陶瓷等工业部门作中碎和细碎各种中硬矿石和岩石用。2、该系列颚式破碎机（颚破）最适宜于破碎抗压强度不高于300MPa（兆帕）的各种软硬矿石，被破碎物料的最大块度不得大于技术参数表所规定。大型破碎机的的安装过程比较的麻烦，需要机器的吊装，在试运行该机时候，应注意仔细检查电路以及配电柜。以防出现意外。大型破碎机在生产过程中
49、应及时注意维护，对出现的异常现象应立即停机进行检查，看是机器的那个部位出现故障，应该及时检修。确保机器的正常运转。颚式破碎机故障排除故障现象1：主机突然停机(俗称：闷车)。原因：1)排料口堵塞，造成满腔堵料；2)驱动槽轮转动的三角皮带过松，造成皮带打滑；3)偏心轴紧定衬套松动，造成机架的轴承座内两边无间隙，使偏心轴卡死，无法转动；4)工作场地电压过低，主机遇到大料后，无力破碎；5)轴承损坏。排除方法：1)清除排料口堵塞物，确保出料畅通；2)调紧或更换三角皮带；3)重新安装或更换紧定衬套；4)调正工作场地的电压，使之符合主机工作电压的要求；5)更换轴承。 故障现象2：主机槽轮、动颚运转正常，但破碎工作停止。原因：1)拉紧弹簧断裂；2)拉杆断裂；3)肘板脱落或断裂。排除方法：1)更换拉紧弹簧；2)更换拉
