一、用途

I.  Application

本机是为满足目前地质、冶金、煤炭、建材、化工、核工业等部门实验室碎样间岩样破碎而设计制造的一种新产品。可用于破碎各种中等硬度的矿石、岩石和其它物料。破碎比大，产物粒度组成均匀，调节方便，能满足化验、选矿等多方面破碎的要求，且接料方便，粉尘少，配有刚玉颚板，是一种新型的无污染破碎设备。

This machine is a kind of new product designed and manufactured to  crush rock samples from the crushing sample room of laboratories in sectors  such as geology, metallurgy, coal, building material, chemicals, and nuclear.  It allows big crushing ratio and uniform grain size of crushed products, and  can be adjusted easily. It can meet crushing requirements in different aspects  such as laboratory test and ore dressing. Besides, it is easy for material  receiving, produces little dust, and is equipped with corundum jaw plate. It is  a new kind of pollution-free crushing equipment.

三、主要结构

III. Main  Structure

本机主要由静颚、动颚、机体、偏心轴、机架、调节机构等部分组成。

This  machine is composed of stationary jaw, moving jaw, body, eccentric shaft,  frame, regulating mechanism, etc.

1、静颚、动颚

1. Stationary Jaw, Moving Jaw

静颚通过偏心轴固定在机体上，偏心轴既起支承作用又起调节作用。静颚上装有固定颚板。动颚上端固连在偏心轴上，下端支承在肘板上。动颚上装有活动颚板。

The  stationary jaw is fixed on the machine body through eccentric shaft. The  eccentric shaft plays both supporting and regulating roles. Fixed jaw plates  are installed on the stationary jaw. The top of the moving jaw is connected to  the eccentric shaft while its bottom is supported on the toggle plate. Active  jaw plate is installed on the moving jaw.

2、机体

2. Body

机体由钢板焊接而成。静颚、动颚、左右衬板，装于机体内。

The  body is welded one with steel plate. Stationary jaw, moving jaw, as well as  left and right lining plates are installed in the body.

3、偏心轴

3. Eccentric Shaft

偏心轴两头通过支承座安装在机体上，中部偏心处安有动颚，通过偏心作用带动动颚作往复曲线运动破碎矿石。

The  two ends of eccentric shaft are mounted onto the machine body through the  supporting seat. Moving jaw is installed on the off-center part. Ores are  crushed when the moving jaw is driven to make reciprocating curvilinear motion  under the eccentric action.

4、机架

4. Frame

机架为多种型钢焊接而成。上面装有机体和电动机，内部装有抽屉。

The  frame is welded one with multiple kinds of steel. Its top is installed machine  body and motor and its inside is installed drawer.

5、调节机构

5. Regulation Mechanism

（1）静颚的调节，旋转偏心轴，静颚的角度发生变化。两颚间得到不同的间隙，从而得到不同破碎比的矿样。

(1)  Adjustment of stationary jaw: Rotate the eccentric shaft and the angle of  stationary jaw changes. Different gaps between two jaws are produced so that  ore samples of different crushing ratios can be produced.

（2）动颚的调节，根据不同的破碎比要求，调节肘板的角度，动颚的运动轨迹发生变化，使破碎机总是处于****破碎状态，保证排料粒度的均匀性，肘板向上调节，两颚间排料口宽度增大，产物粒度大，产量高；肘板向下调节。两颚间排料口宽度减少，产物粒度小而均匀，产量低。

djustment of moving jaw:  Adjust the angle of toggle plate according to different requirements for  crushing ratio and the motion track of moving jaw changes, to enable the  crusher to be in best crushing condition and ensure the uniformity of discharge  size. When the toggle plate is adjusted upward, the width of discharge opening  between the two jaws increases, the granule size is large, and the productive  capacity is high. When the toggle plate is adjusted downward, the width of discharge  opening between the two jaws decreases, the granule size is small and uniform,  and the productive capacity is low.

调节机构在破碎机工作时可单独调节，也可以联合调节。

During the operation  of crusher, the regulating mechanism can be regulated independently or jointly.
