工作原理/ OPERATING PRINCIPLE

電動(dòng)機(jī)通過(guò)減速機(jī)帶動(dòng)磨盤轉(zhuǎn)動(dòng)，物料經(jīng)喂料器從進(jìn)料口落在磨盤中央。隨著磨盤的轉(zhuǎn)動(dòng)，物料在離心力的作用下，向磨盤邊緣移動(dòng)，經(jīng)過(guò)磨盤上的環(huán)形槽時(shí)受到磨輥的碾壓而粉碎，粉碎后的物料在磨盤邊緣被高速氣流帶氣，大顆粒直接落在磨盤上重新粉磨，氣流中的物料經(jīng)過(guò)上部分離器時(shí)，在旋轉(zhuǎn)轉(zhuǎn)子的作用下，粗粉從錐斗落到磨盤重新粉磨，合格細(xì)粉隨氣流一起出磨，通過(guò)收塵裝置收集即為產(chǎn)品。通過(guò)調(diào)整分離器，可達(dá)到不同的粗細(xì)度。

The motor drives the millstone to rotate through the reducer, and the materials fall into the center of the millstone from the feeding inlet through the feeder. As the millstone rotates, the materials under the action of centrifugal force move to the edge of the millstone and are crushed by the grinding roller when passing through the annular groove of the millstone. The crushed materials are carried by high-speed air flow at the edge of the millstone, and large particles directly fall on the millstone for regrinding. When the materials in the air flow pass through the upper separator, the coarse powders fall from the cone bucket to the millstone for re-grinding under the action of the rotating rotor. The qualified fine powders are ground together with the air flow and collected by the dust collector, becoming the products ultimately. By adjusting the separator, different roughness parameters can be achieved.

Specific surface area is 20,000±1,000cm2/g, d97=8.5um. Products can be produced by JLSM-1150 vertical roller mill.

研磨：原料被輸送入主機(jī)后，底部磨盤轉(zhuǎn)動(dòng)的離心力，將原料向外推送至磨輪之間進(jìn)行研磨，三個(gè)磨輪均有單獨(dú)的油壓連桿控制研磨壓力，油壓系統(tǒng)輸出的恒定壓力為65~75kg/cm2，使原料于三個(gè)磨輪于磨盤之間進(jìn)行研磨，油壓系統(tǒng)配備有六個(gè)蓄壓器可吸收顆粒狀原料初步粉碎時(shí)所產(chǎn)生的出來(lái)的振動(dòng)力。

Grinding: After the raw materials are transported to the main engine, the centrifugal force of the bottom millstone pushes raw materials outward the area between the grinding wheels for grinding. Each of the three grinding wheels has an individual hydraulic connecting rod to control the grinding pressure. The constant pressure output by the oil hydraulic system is 65-75kg/cm2, so that the raw materials are ground between the three grinding wheels and the millstone. The oil hydraulic system is equipped with six accumulators to absorb the vibration force generated when the particle raw materials are ground preliminarily.

分級(jí)：原料于磨輪和磨盤之間研磨成細(xì)粉之后，自磨盤周圍溢出，隨著環(huán)帶狀氣流上升，進(jìn)入上端的轉(zhuǎn)動(dòng)錐形分級(jí)葉片區(qū)，經(jīng)過(guò)分級(jí)葉片區(qū)較粗的粉無(wú)法通過(guò)以設(shè)定轉(zhuǎn)速分級(jí)的葉片區(qū)，而直接落在下部繼續(xù)研磨，通過(guò)分級(jí)葉片區(qū)的粉末稱為細(xì)粉，這些細(xì)粉將被收入后段集塵裝置中。依成品要求細(xì)度，可以選擇配裝雙層葉扇式分級(jí)葉片（粗粉），錐形鋁合金分級(jí)葉片（細(xì)粉）或復(fù)合式平轉(zhuǎn)分級(jí)輪（超細(xì)粉）等不同的分級(jí)裝置。

Classification: After the raw materials are ground into fine powders between the grinding wheels and the millstone, they overflow from the periphery of the millstone and enter the rotating conical grouped blade area at the top as the annular air flow rises. The coarser powders passing through the classified blade area cannot pass through the blade area classified at the set rotation speed, but directly fall on the lower part, continuing to be ground. The powders passing through the classified blade area are called fine powders, which will be collected into the dust collector at the rear section. According to the fineness required by the finished product, different classification devices such as double-layer blade-size classifying blade (coarse powder), tapered aluminum alloy classifying blade (fine powder) or composite horizontal rotation stepped gear (ultra-fine powder) can be selected.

氣流：細(xì)粉隨著氣流通過(guò)分級(jí)葉片后，進(jìn)入脈動(dòng)式袋濾器中，集塵裝置收集細(xì)粉后，被分離的空氣會(huì)由風(fēng)車再次進(jìn)入系統(tǒng)中，氣流于整個(gè)系統(tǒng)中呈負(fù)壓狀態(tài)。因此，消除了由于粉塵的散溢而引發(fā)污染環(huán)境的問(wèn)題。若是原料潮濕可加熱氣流加熱裝置，可以使干燥和研磨同時(shí)進(jìn)行。

Airflow: After the fine powder passes through the classified blade with the airflow, it enters the pulse bag filter. After the dust collecting device collects the fine powder, the separated air will be carried out in the system again through the windmill, and the airflow will be in a negative pressure state in the whole system. Therefore, the problem of environmental pollution caused by dust overflow is eliminated. If the raw material is moist, the air flow heating device can be heated. And the drying and grinding can be carried out simultaneously.

控制：經(jīng)由plc編程式工程機(jī)及多種控制元件安裝于電器控制盤上，如電流控制器、機(jī)負(fù)載控制器、變頻器及警報(bào)裝置等遠(yuǎn)程式控制器連線，系統(tǒng)全自動(dòng)運(yùn)轉(zhuǎn)于最佳效率的生產(chǎn)狀態(tài)。

Control: Through programmable touch man-machine and various control components installed on the electrical control panel, such as current controller, machine load controller, frequency converter, alarm device and other remote controllers connected, the system operates fully automatically in the production state with the best efficiency.
