Set of crushing, drying, grinding, grading conveyor in one, the system is simple, compact layout, covering about 50% of the milling system, and can open layout, thus reducing a lot of investment costs.

High milling efficiency: the way the roller grinding disc directly on rolling ground materials, low energy consumption, save energy compared with the milling system 30% to 40%. Less wear and tear: As the roller does not work in direct contact with the disc, and the roller and liner made of high quality material, it has a long life, less wear and tear. Because of the hot air in the mill direct contact with the material, strong drying capacity, vertical mill can save a dryer system, saving footprint, and energy conservation, and by adjusting the air temperature, the material can easily cope with different humidity .

The material in the mill residence time is short, easy to detect and control the particle size and chemical composition, reducing the duplication of milling, more stable product quality.

Roller sleeve and liner are not in direct contact with, and very few products iron and iron contained in the mechanical wear and easy to remove, for when grinding white or transparent materials, products, high whiteness and purity.

Equipped with devices to prevent the roller sleeve and limit direct contact with the disc liner to avoid the destructive impact and severe vibration, so the quality and stability of the finished product plays a significant guarantee.

Overall sealing device, the system working under negative pressure, no dust spills, clean environment, to meet the national environmental protection requirements.



Rotating disc driven by the main motor reducer, while the hot air from the inlet into the vertical mill body, the material falls through the inlet disc center, under the effect of centrifugal force, the material from the disc moves to the edge of the center even after the powder on disc when the grinding roller area by rolling mill rolls, bulk material is directly crushed, after the formation of fine-grained material is squeezed between the bed were crushed tablets. Material crushed to continue to move the edge of the disc until it is taken away by the strong wind flow annulus, the material is brought up in the air flow, the larger particles of material under their own gravity to fall onto the disc again to continue crushing the remaining material then into the air and efficient dynamic separator were graded powder, in the role of efficient dynamic splitter blades, do not meet the requirements of the fineness of the material back on the disc were grinding, and comply with the requirements of the fineness of the material with the flow through the pipeline into the pulse dust collection, discharged through a discharge device is finished powder. When mixed with the material within the host iron and other hard materials with wear debris is moved to the edge of the disc, which can not be due to the large wind from its own weight, fell under the mill chamber is installed at the bottom of the disc scraper plate scraping into the slag after opening, the discharge outside the host.
