一、用途

I.  Application

本機是為滿足目前地質、冶金、煤炭、建材、化工、核工業(yè)等部門實驗室碎樣間巖樣破碎而設計制造的一種新產品。可用于破碎各種中等硬度的礦石、巖石和其它物料。破碎比大，產物粒度組成均勻，調節(jié)方便，能滿足化驗、選礦等多方面破碎的要求，且接料方便，粉塵少，配有剛玉顎板，是一種新型的無污染破碎設備。

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、主要結構

III. Main  Structure

本機主要由靜顎、動顎、機體、偏心軸、機架、調節(jié)機構等部分組成。

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

1、靜顎、動顎

1. Stationary Jaw, Moving Jaw

靜顎通過偏心軸固定在機體上，偏心軸既起支承作用又起調節(jié)作用。靜顎上裝有固定顎板。動顎上端固連在偏心軸上，下端支承在肘板上。動顎上裝有活動顎板。

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、機體

2. Body

機體由鋼板焊接而成。靜顎、動顎、左右襯板，裝于機體內。

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、偏心軸

3. Eccentric Shaft

偏心軸兩頭通過支承座安裝在機體上，中部偏心處安有動顎，通過偏心作用帶動動顎作往復曲線運動破碎礦石。

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、機架

4. Frame

機架為多種型鋼焊接而成。上面裝有機體和電動機，內部裝有抽屜。

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、調節(jié)機構

5. Regulation Mechanism

（1）靜顎的調節(jié)，旋轉偏心軸，靜顎的角度發(fā)生變化。兩顎間得到不同的間隙，從而得到不同破碎比的礦樣。

(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）動顎的調節(jié)，根據不同的破碎比要求，調節(jié)肘板的角度，動顎的運動軌跡發(fā)生變化，使破碎機總是處于****破碎狀態(tài)，保證排料粒度的均勻性，肘板向上調節(jié)，兩顎間排料口寬度增大，產物粒度大，產量高；肘板向下調節(jié)。兩顎間排料口寬度減少，產物粒度小而均勻，產量低。

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.

調節(jié)機構在破碎機工作時可單獨調節(jié)，也可以聯合調節(jié)。

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