一、用途

I. Application

XMB型三輥四筒棒磨機可供冶金、地質、化工、建材和煤炭等實驗室，研究單位及選礦廠進行礦石可選性研究工作時磨細礦石之用，也可供機械、水電、輕工業和農業等方面進行實驗研究工作時磨細少量物料之用。

XMB rod mill of triple-rollers  and four-drums is used to mill ores during the studies of ore separability in  laboratories, research units, and ore dressing plants engaged in metallurgy,  geology, chemicals, building materials, and coal, as well as to mill a small  quantity of materials during experimental studies in fields such as machinery,  water and electricity, light industry, and agriculture.

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、多用途新型磨礦設備?？梢愿伞駜捎?，亦可用鋼球代替作球磨機使用。本設備結構緊湊，使用方便，體積小和重量輕等優點，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規格的浮選機及其他儀器配套使用的理想設備，是定型的實驗室用磨礦設備。

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，根據磨料不同而選擇不同的簡體轉速，變頻技術按“鍵”就能實現，可對于、濕物料同時制樣，可用鋼球代替鋼棒作磨料介質，簡體轉動時間可任意設置，磨樣參數液晶屏幕顯示，人性化設計，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、機器結構維護概述：

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，主動電動機經兩級三角皮帶輪減速使主動輥子有四種不同的轉速以適應各種的速度要求。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產生沖擊，磨剝作用而進行磨礦。兩級皮帶均可通過調整軸承座的兩個支承螺栓而使皮帶保持恰當的松緊以保證有較穩定的工作轉速。

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，可以進行調節，設備出廠時，輥子位置距離以進行調節安裝好。

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.

設備操作面中間設電氣設備門板，裝有全部電氣元件?？總鲃佣说拈T（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.

為了減輕箱體內的聲音共鳴和便于電動機散熱，箱體后面開有百頁風口，兩側面開有手環便于搬動，右端下面還有一長孔是供調節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.
