LYH1008 Series Vertical Grinding Mill

LYH1008 series vertical mill is a new type of equipment designed to absorb foreign technology. It grinds the material (0-15MM) on the rotating grinding disc by rolling the grinding roller with pressure to achieve the corresponding fineness of 325-2000 mesh. The main technology is reflected in the full contact between the grinding roller, grinding disc, and the material and the classification accuracy of the classification system. It is suitable for grinding ultra-fine powder materials in metallurgy, electric power, chemical industry, and refractory materials, especially non-metallic minerals.

The vertical grinding mill integrates the functions of grinding, powder selection, and drying. Compared with other grinding equipment such as ball mill and Raymond mill, it has the advantages of low energy consumption, high grinding efficiency, low wear, strong drying capacity, easy adjustment of product fineness, uniform particle size, easy control of chemical composition, low noise, less dust, simple operation, convenient replacement of wearing parts, simple system process flow, small footprint, and good comprehensive economic benefits. Therefore, the vertical mill is increasingly valued and widely used by the powder processing industry.

  • Application

    The materials that vertical grinding mill can be used for grinding and crushing mainly include: calcite, limestone, pyrophyllite, barite, fluorite, glaze, slag, wollastonite, kaolin, vermiculite, mica, feldspar, brucite, spores, potassium salt slag, garnet, quartz, ilmenite, magnesium oxide, magnesium hydroxide, dolomite and other industries.

  • Working Principle

    The motor drives the grinding disc to rotate through the reducer. The material falls into the center of the grinding disc from the feed port. At the same time, hot air enters the mill from the air inlet. Under the action of centrifugal force, the material moves to the edge of the grinding disc. When passing through the annular groove on the grinding disc, it is crushed by the grinding roller. The crushed material is carried by the high-speed airflow at the wind ring at the edge of the grinding disc. Large particles fall directly on the grinding disc for re-grinding. When the material in the airflow passes through the classifier, under the action of the rotating rotor, the coarse powder falls on the grinding disc for re-grinding. The qualified fine powder is discharged from the mill with the airflow and collected in the powder collecting device as the product. The material containing water is dried in the process of contact with the hot gas to achieve the required product moisture. The airflow is recycled. During the circulation process, a small amount of excess gas together with the lighter impurities in the finished product are collected by the branch vacuum cleaner in the system for low-grade product processing, thus forming a very scientific and advanced process.

  • Features of Vertical Mill

    Low operating cost: high grinding efficiency, low power consumption, and 40-50% less power consumption compared with other grinding equipment such as ball mills and Raymond mills. Low wear, special materials for roller sleeves and linings, long service life, reduced metal pollution of products, and reduced operating costs. It can be equipped with an external circulation device to further reduce power consumption and improve product precision.

    Low construction cost: Compared with ball mill systems, vertical mills can reduce floor space by about 50% and construction costs by about 70%. Since crushing, drying, grinding, and graded transportation are integrated into one, the system is simple, so the construction cost is low.

    Easy and reliable operation: equipped with automatic control devices, remote control can be realized, and the operation is simple and easy. Equipped with a device to prevent direct contact between the roller sleeve and the grinding disc lining, there will be no destructive and violent vibration.

    Easy maintenance: by turning the boom through the maintenance cylinder, the roller sleeve and lining can be replaced in a very short time.

    Less pollution: small vibration, low noise, the system is in negative pressure operation, and there is no dust spillage.

    Stable product quality: the material stays in the mill for a short time, making it easy to detect and control the product particle size and chemical composition. The machine is equipped with a high-precision classifier to classify products from 325 mesh to 2000 mesh, with high grading accuracy, precise cutting particles, and stable product quality.

  • Vertical Grinding Mill Components

    Motor: The driving force of the mill, typically a three-phase variable speed drive (VSD) induction motor. It powers the rotation of the grinding table.

    Gearbox: Reduces the high speed of the motor to a slower, more suitable speed for the grinding table.

    Grinding Table: A rotating circular platform where the material to be ground is fed. It's often coated with wear-resistant materials.

    Grinding Rollers: Cylindrical rollers that rotate above the grinding table. They apply pressure to the material on the table, causing it to be crushed and ground.

    Hydraulic System: Controls the pressure and position of the grinding rollers.

    Classifier: Separates the ground material into fine and coarse particles. Fine particles are discharged as the final product, while coarse particles are returned to the grinding table for further processing.

    Thermal System: Includes a heat source (often hot air) to dry the material and aid in the grinding process.

    Dust Collector: Captures and removes dust particles generated during the grinding process.

    Feed System: Introduces the material to be ground into the mill.

    Discharge System: Removes the finished product from the mill.
