一、用途

I. Application

本機是為滿足目前地質(zhì)、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(shè)計制造的一種新產(chǎn)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(chǎn)物粒度組成均勻，調(diào)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(shè)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.

二、主要技術(shù)參數(shù)

Ⅱ.Technical parameter

三、主要結(jié)構(gòu)

III. Main Structure

本機主要由靜顎、動顎、機體、偏心軸、機架、調(diào)節(jié)機構(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(diào)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(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(fù)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(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(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)機構(gòu)在破碎機工作時可單獨調(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.
