主要結構說明

Main Structure

本機主要由給礦、磨礦、排礦、分級、運輸?shù)任宀糠纸M成。

This machine mainly consists of five parts i.e. feeding part, grinding part, discharging part, classifying part, and conveying part.

(一)、給礦部分

(I) Feeding Part

由一個礦倉式圓筒給礦機及一個蝸形給礦器組成。給礦方法在礦倉的閘門打開后通過圓筒的轉動使礦倉內(nèi)的物料連續(xù)而均勻地送進蝸形給礦器外殼中,再由蝸形給礦器連同水一起送進磨礦筒內(nèi),給礦量是用調(diào)節(jié)閘門板的開口大小及圓筒轉速來控制。圓筒由螺旋運輸機軸上的皮帶塔輪用皮帶傳動,有兩種速度。蝸形給礦器為一平面螺旋形的勺子,用來直接向筒體內(nèi)部輸送原礦和分級機的返砂。

The feeding part is composed of a cylindric feeder of ore storage bin type and a snail feeding device. The feeding method is: After the gate of the ore storage bin is opened, materials in the ore storage bin are fed continuously and evenly into the shell of the snail feeding device through the rotation of drum; then they are fed into the milling drum by the snail feeding device together with the water. The feeding quantity is controlled through adjusting the size of the opening of the gate plate and rotating speed of the drum. The drum is driven at two speeds through the belt by the belt cone on the shaft of screw conveyor. The snail feeding device is a scoop in the shape of planar spiral which is used to convey raw ores and return sand from the classifier directly to the inside of drum.

(二)、磨礦部分

(II) Grinding Part

是一個Φ420×600磨礦筒體,其內(nèi)壁鑲有六塊波紋形錳鋼襯板,外壁焊有兩個輪圈。輪圈支承在兩對托滾上;蝸形給礦器固定在筒體的一端,另一端則為溢流排礦口。筒體的旋轉是由電動機經(jīng)三角皮帶和齒輪二級減速后,使一對主動托滾轉動,利用托滾與輪圈的磨擦實現(xiàn)傳動達到的。

The grinding part is a Φ420×600 grinding drum. Its inner wall is lined with six corrugated manganese steel liners and its outer wall has two wheel rims. The wheel rims are supported on two pairs of rollers. At one end of the drum is snail feeding device and at the other end of the drum is overflow discharging mouth. The function of transmission is served by the rubbing of roller and wheel rims when the motor gets one pair of drive roller to rotate through the V-belt and secondary gear reducer.

(三)、排礦部分

(III) Discharging Part

磨礦產(chǎn)品經(jīng)排礦端蓋口自行溢出,經(jīng)過排礦溜槽的斜度自動的流入分級機,溜槽上端焊有一軟管接頭,用膠管與給水管接通,給水管上裝有旋塞,以便開、關和調(diào)節(jié)沖洗的水量。溜槽外側插上一個擋蓋,以免排礦口礦漿往外飛濺。

The grinding products automatically overflow when passing the cover at the discharging end. They automatically flow into the classifier through the tilting discharging chute. A hose coupler is welded on the top of the chute which are connected with rubber pipes and feed pipes. On the feed pipes are taps which are used to turn on and turn off water as well as adjust the water flow. A retaining cap is inserted to the outside of the chute to avoid the slurry at the discharging mouth from splashing out.

(四)、分級部分

(IV) Classifying Part

是一個Φ150×1400螺旋運輸機,利用排礦溜槽入口孔作為其一端的支點,整個分級機可繞這個支點轉動一定的角度,以達到不同的坡度要求,另一端則用一螺桿支承,轉動其上代套筒螺母的手輪,即可調(diào)節(jié)分級機的坡度,以便控制返砂量的大小及溢流的細度。

The classifying part is a Φ150×1400 screw conveyor. It takes the inlet of discharging chute as the fulcrum of its one end around which the whole classifier revolves for a certain angle to meet the requirement of different gradients. Its other end is supported with a screw. The gradient of the classifier can be adjusted when the hand wheel of sleeve nut on it is turned, so as to control the amount of return sand and fineness of effusion.

(五)、運輸部分

(V) Conveying Part

是一個Φ90×420的螺旋運輸機,將分級機與蝸形給礦器外殼連接起來,把分級機的返砂連續(xù)均勻地送入蝸形給礦器外殼,再與礦倉式給礦機下來的原礦一起由蝸形給礦器送入磨機筒體內(nèi)。使分級機與磨機組成一個閉路磨礦系統(tǒng),實現(xiàn)連續(xù)磨礦作業(yè)。

The conveying part is aΦ90×420 screw conveyer. The conveying process is: The classifier and snail feeding device is linked; the return sand from the classifier is fed continuously and evenly to the shell of the snail feeding device, and the snail feeding device then conveys it and the raw ores from the feeder into the grinding drum, so that the classifier and mill form a closed-circuit grinding system and continuous grinding can be realized.

上述各部分與傳動系統(tǒng)、供水系統(tǒng)、電氣設備等均裝好在機架上,成臺出廠,安裝時不需另設基礎。在車間內(nèi)擺好位置以后,略將水平調(diào)好,清理包裝油脂,檢查潤滑情況;接水管、電源;試開車確定磨機運轉方向。符合要求后,即可按操作程序進工作。

All the parts listed above and the drive system, water supply system, and electric equipment shall be installed on the frame to be shipped in complete set. During installation, it is not necessary to add new foundations. When it is placed in the workshop, adjust the supporting plane slightly, remove oil staining on the package, examine the lubricating condition, connect it to water and power source, as well as determine the operating direction of mill through test run. When all relevant requirements are conformed to, the equipment can be operated according to procedures.
