Introduction Of Ultrafine Mill
The basic structure consists of the main unit, fan, powder separator, cyclone dust collector, dust collector, pipe device, and motor. The main unit consists of a frame, an air inlet volute, a shovel, a grinding roller, a grinding ring, and a cover. Ancillary equipment also includes jaw crusher, bucket elevator, electromagnetic vibration feeder (small size, can be sealed, can be fed continuously and evenly), silo, power distribution cabinet (control the entire line), etc.
Applied materials Of Ultrafine Mill
Applications: It can be applied in the areas of metallurgy, building materials, chemicals, mining such as quartz, feldspar, clay, kaolin, bentonite, calcite, talc, barite, fluorite, gypsum which Mohs hardness is below 7.
Working Principle of Ultrafine Mill
Large size rocks are put into the storage bin through the hoist, and they will be evenly delivered to the host grinding chamber by the electromagnetic vibrating feeder. The material entering the grinding chamber is scooped up by the blade and crushed between the grinding roller and ring. The fan blows the wind into the grinding chamber, then the wind blows the powder into the analyzer, and sorts it.
If the size of the finished product is not standard, it will be fell into the grinding chamber again. While the qualified fine powder will enter the finished cyclone collector with the airflow. After the fine powder is separated from the air and discharged from the discharge port, which is a finished product. The air returns to the fan from the upper return duct, and the air path is cyclic, and it flows under negative pressure.
Advantages of Ultrafine Mill
The design of the grinding roller is original, the material selection is reasonable, robust and reliable, and the pressure on the processing material is increased by 15%-20%;
The number of bearing replacements is small, the service lifespan is long, and the life of the whole machine is extended by 3-5 times compared with other mills;
A new type of high-efficiency pulse dust removal equipment and a silencer are installed to eliminate dust, noise, and other pollution, which establishes a green production workshop;
In the situation of the same yield and fineness, the system has a better price than the Jet Mill.
