LSM系列超细立式磨粉机是金仑公司以几十年的生产经验为依托，吸取德国、日本、中国台湾超细立磨技术，并采用优质的耐磨配件，研发出的集破碎、粉碎、分级输送于一体的磨粉行业的理想设备。设计技术团队与国内高校机械科研团队合作，超细立磨的成品细度******可高达500目。

LSM超细立磨设备，广泛应用于碳酸钙、滑石、铁粉、炭黑、膨润土、钼粉、石灰石、硅灰石、白云石、云母、超细水泥、电力、冶金、化工等行业。用于将块状、颗粒状及粉状原料磨成所要求的的粉状物料。

LSM series ultra-fine vertical mill is developed by Jinlun Company, based on decades of production experience and absorbing the technology of ultra-fine vertical mill from Germany, Japan and Taiwan, China as well as adopting high-quality wear-resistant accessories. It is developed to be an ideal equipment in the mill industry, which integrates the functions of crushing, shattering and grading transportation. The technical design team cooperates with the mechanical research team of domestic universities. And the maximum fineness of the finished products of ultra-fine vertical mill can reach XXX.

LSM series ultra-fine vertical mill is widely used in calcium carbonate, talc, iron powder, carbon black, bentonite, molybdenum powder, limestone, wollastonite, dolomite, mica, ultra-fine cement, electricity, metallurgy, chemical industry, etc. It is used for grinding blocky, granular and powdery raw materials into the powder materials meeting the requirements.

工作原理/ OPERATING PRINCIPLE

电动机通过减速机带动磨盘转动，物料经喂料器从进料口落在磨盘。随着磨盘的转动，物料在离心力的作用下，向磨盘边缘移动，经过磨盘上的环形槽时受到磨辊的碾压而粉碎，粉碎后的物料在磨盘边缘被高速气流带气，大颗粒直接落在磨盘上重新粉磨，气流中的物料经过上部分离器时，在旋转转子的作用下，粗粉从锥斗落到磨盘重新粉磨，合格细粉随气流一起出磨，通过收尘装置收集即为产品。通过调整分离器，可达到不同的粗细度。

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.

技术优势/ TECHNICAL ADVANTAGES

比表面积20000±1000cm²/g、d97=8.5um产品可有JLSM-1150立式磨粉机产出。

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

研磨：原料被输送入主机后，底部磨盘转动的离心力，将原料向外推送至磨轮之间进行研磨，三个磨轮均有单独的油压连杆控制研磨压力，油压系统输出的恒定压力为65~75kg/cm²，使原料于三个磨轮于磨盘之间进行研磨，油压系统配备有六个蓄压器可吸收颗粒状原料初步粉碎时所产生的出来的振动力。

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.

分级：原料于磨轮和磨盘之间研磨成细粉之后，自磨盘周围溢出，随着环带状气流上升，进入上端的转动锥形分级叶片区，经过分级叶片区较粗的粉无法通过以设定转速分级的叶片区，而直接落在下部继续研磨，通过分级叶片区的粉末称为细粉，这些细粉将被收入后段集尘装置中。依成品要求细度，可以选择配装双层叶扇式分级叶片（粗粉），锥形铝合金分级叶片（细粉）或复合式平转分级轮（超细粉）等不同的分级装置。

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.

气流：细粉随着气流通过分级叶片后，进入脉动式袋滤器中，集尘装置收集细粉后，被分离的空气会由风车再次进入系统中，气流于整个系统中呈负压状态。因此，******了由于粉尘的散溢而引发污染环境的问题。若是原料潮湿可加热气流加热装置，可以使干燥和研磨同时进行。

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：经由plc编程式工程机及多种控制元件安装于电器控制盘上，如电流控制器、机负载控制器、变频器及警报装置等远程式控制器连线，系统全自动运转于******效率的生产状态。

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.
