Vertical Roller Mill In china has obtained breakthrough

With the rapid development of scientific and technological progress and steel industries, the vertical roller mill equipment in China has also rapidly developed and continuously obtained breakthrough, whose application has been further promoted. The first is the application of the permanent magnet of the vertical roller mill in weak magnetic field , and a new high-performance neodymium iron boron (Nd-Fe-B) rare earth permanent magnet materials, which has significantly improved the magnetic induction the performance of equipment.

Then all kinds of vertical roller mill and the strong vertical roller mill came out were improved. The high gradient vertical roller mill was enhanced to a new level. At present, China's development and production of vertical roller mill equipment is a world leader except the superconducting vertical roller mill equipment. Superconducting vertical roller mill equipment has come out and it has developed from the laboratory-type to semi-industrial type. Now it has entered the industrial application stage.

There are several advantages of fine-grained dry vertical roller mill equipment of weak magnetic field. For example, the process is simple and does not consume water, which saves dehydration, concentration and filtration operations. Therefore the investment and cost is low and the plant area is small. However, the drawback is that technical indicators are sometimes low, especially with the rising demand for environmental protection, dust pollution caused by dry separator is difficult to drawn.
