Superfine Vertical Mill

LUM superfine vertical mill is developed by Shanghai Yingyong based on the ultra-fine vertical mill, combined with years of experience in mill research and manufacturing. It is a device specially used in the ultrafine grinding industry, which can realize the functions of ultrafine grinding, grading and conveying. It is widely used in chemical industry, metallurgy, non-metallic minerals and other industries.


    LUM ultra-fine vertical mill is mainly composed of electric motor, reducer, grinding roller device, grinding disk device, pressurizing device, powder separator, body and oil station.

    Input: 0-10mm
    Capacity: 5-18T/H
    Materials: coal, mica, talc, graphite, quartz stone, limestone, dolomite, kaolin, coal gangue and more than 200 kinds of materials
    Application fields: chemical industry, metallurgy, mining, non-metallic mines and other industries.

    Working Principle

    The main motor drives the grinding disc through the reducer, while the wind enters the vertical mill body through the air inlet. The material falls into the center of the grinding disc through the downward feeding port of the screw feeder, and under the action of centrifugal force, the material moves evenly from the center to the edge of the grinding disc. When the material passes through the grinding roller channel area on the grinding disc, it is crushed by the grinding roller, and the large pieces of material are directly crushed.

    The material being ground continues to move towards the edge of the grinding disc until it is brought away by the strong airflow at the wind ring. Larger granular will fall back onto the grinding disc for further grinding. Under the influence of the rotor blades, as the material in the air stream passes through the upper separator, the coarse particles return to the grinding disc again for grinding. The qualified fine powder comes out of the mill together with the air stream and is collected by the system's powder collector, and these collected powders are the products ground by the vertical mill.

    In the process of material movement, impurities such as iron blocks in the material will reach the edge of the grinding disc along with the material. Due to their heavy weight, they cannot be blown up by the wind, so they will fall to the lower cavity of the mill, and will be scraped into the slag discharge port by the scraper, and finally discharged out of the machine.

    By adjusting the rotational speed of the rotor of the multi-head separator, we can obtain different fineness qualified products. In addition, by adjusting the pressure of the hydraulic system, the pressure of the roller mill can be adjusted to accommodate raw materials of different hardness.

    Energy-Saving Multi-Head Powder Separation Innovation
    With high separation efficiency and accuracy, the LUM Ultrafine Vertical Grinding Mill Multihead Separator is capable of quickly separating powders of the required particle size. Thus it enhance the efficiency and output of the overall production line.
    Higher Production Efficiency, Better Quality
    The multi-head powder selection machine of LUM ultrafine vertical roller mill can effectively remove impurities and excessively large or small particles from the powder, making the particle size distribution of the final product more uniform and precise. It’s beneficial to improve product quality and performance, and meet customer requirements for fine powder products.
    Easy Operation and Maintenance
    There is no direct contact between the grinding roller and the grinding disc of the LUM superfine vertical mill, so the wear is less and the service life is longer. In case of failure, the grinding rollers can be easily turned out for maintenance, which is convenient and reduces the loss caused by downtime.
    Smooth Operation of Equipment
    LUM ultrafine vertical mill is equipped with mechanical and electronic limit devices, which effectively avoid the occurrence of destructive shocks and vibrations. At the same time, the grinding roller pressurization control method with PLC/DCS automatic control is adopted to achieve accurate control without manual operation. In addition, the equipment is equipped with a grinding roller lubrication station, which can effectively prevent the problem of excess oil leakage while being fully lubricated.
    Low Noise and Clean and Environmental Protection
    LUM ultrafine vertical mill adopts advanced structure design, high quality material and manufacturing process with effective sealing system and enhanced dust collection and treatment device, so it has low vibration, low noise, good overall sealing, and no dust spillage.
    Wide range of applicable materials
    The ultra-fine vertical mill is suitable for grinding and processing a wide range of materials, including but not limited to ores, non-metallic minerals, chemical raw materials, building materials and other fields, with a wide range of application prospects.
