XPC Model Sealed Jaw Crusher is  a new generation of crushing equipment with easy open of dynamic and static  jaws, convenient clean-up and no blending of samples. It is capable of fine and  medium crushing a variety of ores and materials with compressive strength of 24kg/cm2 and below. with great  crushing ratio, uniform particle size and adjustment of output size.

一、设备主要结构及工作原理

I. Main Structure and Working  Principle

本机主要由机体、动颚、偏心轴、颚板、飞轮、皮带轮、活动部件、电动机、进料斗、接料斗等另部件组成。

This machine is mainly composed of machine body, moving jaw,  eccentric shaft, jaw plate, flywheel, belt pulley, moving part, motor, feed  hopper and receiving hopper.

运动由电动机皮带轮三角通过皮带皮带轮传动偏心轴，使动颚按照已调整好的轨迹进行运动，从而将破碎腔内的物料进行破碎。

The three angles of motor pulley drive the eccentric shaft through  the belt pulley to get the moving jaw to move along the already adjusted track,  so as to crush the materials in the crushing chamber.

机提系整体钢结构，前壁上装有固定颚板。在破碎腔左右的机架侧壁上装有边护板以防机架侧壁的磨损。

The machine body is all steel structure. Fixed jaw plate is  mounted on its front wall. Edge plates are mounted on the side wall of frame on  the left and right of crushing chamber, to prevent the abrasion of side wall of  frame.

动颚为一成型的铸造件，正面装有活动颚板。其上部借偏心轴与滚动轴承悬挂在机架上，下部支承在活动部件上，并与活动部件成滚动接触。在偏心轴两端装有飞轮和带槽的皮带轮。机体连接机座，电动机滑道用螺栓固定在机座上。

The moving jaw is a molded casting part. On its front are  installed active jaw plates. On its top, the eccentric shaft and rolling  bearings hang over the frame. Its bottom is supported on the moving parts and  is in rolling contact with the moving parts. At the two ends of the eccentric  shaft are installed flywheel and pulley with groove. The machine body is  connected to the machine base and the slideway of the motor is fixed onto the  machine base with bolts.

在动颚的支撑系统中，有铆销联接装置，当破碎物中混有不能破碎的硬物（如铁块等）时，即破碎机在超负载的情况下，铆销会迅速断裂，起着保险作用，保护破碎机其它重要机件不受损伤。

The supporting system of moving jaw is equipped with riveting pin  connection device. When there are hard objects that can not be crushed (e.g.  pieces of iron) in the materials being crushed, i.e. the crusher is overloaded,  the rivering pin will rupture rapidly, playing a protective role, to keep other  important parts of crusher from being damaged.

在机器左边装有带调整节距的把手，此把手是调节排料口大小的。通过调节把手，可调整排料口间距。同时在颚板磨损时，通过该把手的调节，对排料口间距进行补偿。

A handle equipped with the function of pitch adjustment is  installed on the left of the machine. This handle is used to adjust the size of  discharge opening. The gap between the discharge openings can be adjusted  through the adjustment of handle. In addition, when the jaw plate is abraded,  the gap between discharge openings can be compensated through the adjustment of  the handle.
