二、特點

II. Characteristic

XMB型三輥四筒棒磨機，是一種實驗室用小型、輕便、多用途新型磨礦設(shè)備?？梢愿?、濕兩用，亦可用鋼球代替作球磨機使用。本設(shè)備結(jié)構(gòu)緊湊，使用方便，體積小和重量輕等優(yōu)點，為實驗室中普遍使用的XFD－63系列單槽浮選機和XFG-63型掛槽浮選機或相應(yīng)規(guī)格的浮選機及其他儀器配套使用的理想設(shè)備，是定型的實驗室用磨礦設(shè)備。

XMB rod mill of triple-roller and four-drums is a kind of small, light, multifunctional, and new ore grinding equipment used in laboratory. Dry grinding and wet grinding can be adopted to grind materials. Besides, steel balls can replace steel bars to be used in ball mills. This equipment enjoys compact structure, easy use, small size, and light weight. It is ideal equipment used with the XFD-63 single-trough flotation machine and XFG-63 hanging trough flotation machine or flotation machine of corresponding specifications, and other instrument. It is a kind of prototype grinding equipment used in laboratory.

可單筒或多筒同時磨料，因此制樣量大小可同時選擇，而且同時制樣的品種較多：也可作混料用，根據(jù)磨料不同而選擇不同的簡體轉(zhuǎn)速，變頻技術(shù)按“鍵”就能實現(xiàn)，可對于、濕物料同時制樣，可用鋼球代替鋼棒作磨料介質(zhì)，簡體轉(zhuǎn)動時間可任意設(shè)置，磨樣參數(shù)液晶屏幕顯示，人性化設(shè)計，透明外罩，觀察操作更方便 。

Materials can be grinded in one drum or more than one drum simultaneously. Therefore, the size of sample can be selected at the same time. Besides, there are many types of samples so that they can be used for mixing materials. The rotating speed of drum is selected according to grinding materials and change in frequency can be realized only with the pressing of key. However, for simultaneous grinding of dry and wet materials, steel balls can replace steel bar to be used as grinding media. The rotating time of drum can be set freely and parameters of grinding samples are displaced on LCD screen. Besides, it is equipped with transparent outer cover, making it easier for observation and operation.

四、機器結(jié)構(gòu)維護概述：

IV. Structure

XMB型三輥四筒棒磨機由主機和磨礦滾筒所組成。

XMB rod mill of triple-roller and four-drums consists of the main body and mill drums.

磨礦滾筒放在主機上部橡膠輥子上，主動電動機經(jīng)兩級三角皮帶輪減速使主動輥子有四種不同的轉(zhuǎn)速以適應(yīng)各種的速度要求。磨礦滾筒放在輥子上，因受摩擦力的作用在主、從動輥子上滾動，使磨礦滾筒中的鋼棒在筒壁內(nèi)產(chǎn)生沖擊，磨剝作用而進行磨礦。兩級皮帶均可通過調(diào)整軸承座的兩個支承螺栓而使皮帶保持恰當?shù)乃删o以保證有較穩(wěn)定的工作轉(zhuǎn)速。

The mill drum is placed on the rubber roller on the top of the main body. The drive motor enables the drive rollers to get four-grade rotate speed, through speed reduction of the two-grade V-belt pulley. Since the mill drum is placed on the roller, it rolls on the drive roller and driven roller under the action of frictional force, getting the steel bar in the mill drum to produce impacting and grinding effects so that the materials can be grinded. Through the adjustment of the two support bolts of bearing pedestal, appropriate tightness of the two-grade belts can be kept to ensure stable rotating speed.

主、從動輥子間距離，按選用的磨礦滾筒的大小，可以進行調(diào)節(jié)，設(shè)備出廠時，輥子位置距離以進行調(diào)節(jié)安裝好。

The distance between the drive roller and driven roller can be adjusted according to the number of selected mill drums. When the equipment is ready for shipment, it is better to adjust distance between rollers.

設(shè)備操作面中間設(shè)電氣設(shè)備門板，裝有全部電氣元件。靠傳動端的門（左門）是供檢查傳動部份和變換三角皮帶時用，另一端（右門）是供存放筒體和工具時使用。

In the center of the equipment’s operative surface are installed doors for electric equipment. The door close to the transmission end (the left door) is used for the examination of transmission part and change of V-belt. The door at the other end (the right door) is used for the storage of cylinder and tools.

為了減輕箱體內(nèi)的聲音共鳴和便于電動機散熱，箱體后面開有百頁風(fēng)口，兩側(cè)面開有手環(huán)便于搬動，右端下面還有一長孔是供調(diào)節(jié)三角皮帶松緊時使用。

To reduce sound resonance in the box and facilitate heat radiation of motor, louver wind gaps are left at the back of the box. Handles are added to the two sides of the box, to make easier for its movement. On its right bottom, there is a long hole which is used for adjusting the tension of V-belt.
