Why FTM Ultrafine Grinding Mill ?

This machine can be used to process all kinds of non-flammable and non-explosive mineral materials with mosh hardness below 9.3 and humidity below 7%. It is the perfect choice for materials such as quartz, feldspar, calcite, limestone, talc, marble, granite, dolomite, coal, iron ore and so on. What’s more, the fineness of finished products can be adjusted between 0.18mm and 0.01mm (80 mech-1250 mechs), and some materials can reach more than 2000 mesh.

After the large block of stone is fully crushed by the crusher, it is evenly fed into the storage bin from the bottom to the top by the bucket elevator, and then sent to the main machine by the vibrating feeder in an orderly manner. The material entering the grinding chamber is scooped up by the blade, pressed and crushed between the grinding roller and the ring, and blown into the grinding chamber under the action of the fan, blowing the powder into the analyzer for sorting. The powder that does not meet the fineness requirement is re-dropped into the grinding chamber for processing. The qualified fine powder enters the finished cyclone collector with the airflow, and is separated from the air and discharged from the discharge port to be finished products. The air returns to the fan from the upper return air duct to form a circulating air path, which can flow under negative pressure.

Advantages

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 consumes only one-third of the airflow grinding mill.
