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.

二、主要技術(shù)參數(shù)

Ⅱ.Technical parameter

三、主要結(jié)構(gòu)

III. Main  Structure

本機(jī)主要由靜顎、動(dòng)顎、機(jī)體、偏心軸、機(jī)架、調(diào)節(jié)機(jī)構(gòu)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(dòng)顎

1. Stationary Jaw, Moving Jaw

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

2. Body

機(jī)體由鋼板焊接而成。靜顎、動(dòng)顎、左右襯板，裝于機(jī)體內(nèi)。

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(guò)支承座安裝在機(jī)體上，中部偏心處安有動(dòng)顎，通過(guò)偏心作用帶動(dòng)動(dòng)顎作往復(fù)曲線運(yùn)動(dòng)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(jī)架

4. Frame

機(jī)架為多種型鋼焊接而成。上面裝有機(jī)體和電動(dòng)機(jī)，內(nèi)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(diào)節(jié)機(jī)構(gòu)

5. Regulation Mechanism

（1）靜顎的調(diào)節(jié)，旋轉(zhuǎn)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(dòng)顎的調(diào)節(jié)，根據(jù)不同的破碎比要求，調(diào)節(jié)肘板的角度，動(dòng)顎的運(yùn)動(dòng)軌跡發(fā)生變化，使破碎機(jī)總是處于****破碎狀態(tài)，保證排料粒度的均勻性，肘板向上調(diào)節(jié)，兩顎間排料口寬度增大，產(chǎn)物粒度大，產(chǎn)量高；肘板向下調(diào)節(jié)。兩顎間排料口寬度減少，產(chǎn)物粒度小而均勻，產(chǎn)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(diào)節(jié)機(jī)構(gòu)在破碎機(jī)工作時(shí)可單獨(dú)調(diào)節(jié)，也可以聯(lián)合調(diào)節(jié)。

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