Grate Ball Mill

Grate mills incorporate grate plates and discharge cones at the mill's tail to improve the discharge method and prevent over-grinding. Compared to overflow discharge methods, they provide smoother material flow and higher grinding efficiency. Our grate mills, MQG1245 to MQG3511, are available in ten sizes, equipped with motors ranging from 13.1kW to 220kW, capable of grinding various ores with an hourly output of 1.7t to 73t.

  • Application

    Widely used in power generation, building materials, metallurgy, chemicals, and non-metallic industries.

    Product Introduction

    Grate mills are key equipment for re-grinding materials after crushing and batching in a crusher. They are primarily used for grinding raw materials in cement plants, but can also be used in power generation, metallurgy, chemical industry, and other industries to grind various ores and other grindable materials. They offer high production capacity, high efficiency, and are energy-efficient and environmentally friendly.

    Key Advantages
    ● The liner is cast from high-quality, wear-resistant material, offering excellent wear resistance and a long service life.
    ● It is highly adaptable to fluctuations in material physical properties (such as particle size, moisture content, and hardness).
    ● The product has a uniform, easily adjustable particle size and a high yield rate.
    ● It offers high production capacity, a high crushing ratio, and adaptability to diverse operating conditions. It also features excellent sealing performance.

    Operating Principle
    When the motor drives the bridge mechanism through a reducer, the grinding media adheres to the inner wall of the mill due to centrifugal force and rotates with it. Once lifted to a certain height, gravity and centrifugal force cause the media to fall, crushing the material within. In addition to the cyclical motion of the grinding media, it also experiences sliding and rolling, resulting in a grinding action between the grinding media, the liner, and the material being ground, resulting in a finer grinding process. While the material is being crushed and ground by impact, the height difference between the feed and discharge ends causes the material to flow slowly from the feed end to the discharge end, completing the grinding process.

  • Coal Mill Explosion-Proof Bag Dust Collector Coal Mill Explosion-Proof Bag Dust Collector
    The TQMM series coal mill explosion-proof bag dust collector is a new high-performance bag dust collector developed by A.BITION (Shanghai) R&D Center based on the airbox pulse bag dust collector. It features an explosion-proof mechanism and explosion-proof valves, making it suitable for pulverized coal preparation systems and the collection of flammable and explosive dust. It utilizes an advanced, chambered, offline cleaning method to prevent re-adsorption of cleaned dust. This system features high cleaning capacity, excellent cleaning results, low system resistance, long filter bag life, and high dust removal efficiency. The entire system utilizes PLC automatic control, and parameters can be adjusted according to operating conditions. The TQMM series dust collectors are available in various sizes, with varying numbers of chambers and filter bags. The number of bags per chamber is 32, 64, or 96, and the filter bag size is increased to 130mm x 2450mm.
