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.
