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、設備主要結構及工作原理

I. Main Structure and Working  Principle

本機主要由機體、動顎、偏心軸、顎板、飛輪、皮帶輪、活動部件、電動機、進料斗、接料斗等另部件組成。

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.

運動由電動機皮帶輪三角通過皮帶皮帶輪傳動偏心軸，使動顎按照已調整好的軌跡進行運動，從而將破碎腔內的物料進行破碎。

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.

機提系整體鋼結構，前壁上裝有固定顎板。在破碎腔左右的機架側壁上裝有邊護板以防機架側壁的磨損。

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.

動顎為一成型的鑄造件，正面裝有活動顎板。其上部借偏心軸與滾動軸承懸掛在機架上，下部支承在活動部件上，并與活動部件成滾動接觸。在偏心軸兩端裝有飛輪和帶槽的皮帶輪。機體連接機座，電動機滑道用螺栓固定在機座上。

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.

在動顎的支撐系統中，有鉚銷聯接裝置，當破碎物中混有不能破碎的硬物（如鐵塊等）時，即破碎機在超負載的情況下，鉚銷會迅速斷裂，起著保險作用，保護破碎機其它重要機件不受損傷。

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.

在機器左邊裝有帶調整節距的把手，此把手是調節排料口大小的。通過調節把手，可調整排料口間距。同時在顎板磨損時，通過該把手的調節，對排料口間距進行補償。

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.
