GRM vertical mill is a grinding equipment successfully developed by Xinxiang Great Wall Machinery on the basis of the introduction of vertical grinding technology. Xinxiang Great Wall Machinery has accumulated more than 200 sets of VARIOUS SPECIFICATIONS GRM series vertical grinding, and the products are all over the country and are exported to Indonesia, Uzbekistan, South Korea and other countries and regions.

Process introduction
The material unloading tube falls to the center of the grinding disc, and the grinding disc rotating at constant speed is evenly dispersed and flattened outward by the action of centrifugal force, so that it forms a material bed of a certain thickness, and the material is crushed by multiple grinding rollers on the grinding disc at the same time and is crushed. Under the continuous drive of centrifugal force, the material continues to move to the outer edge of the grinding disc, and the material leaving the grinding disc encounters the hot gas entering the mill through the wind ring and rises accordingly, and enters the separator through the middle shell of the mill, in the process, the material and the hot gas are fully exchanged, and the moisture is quickly evaporated. The separator controls the fineness of the finished product at the roller mill outlet, and the particles larger than the specified size are separated and fall back to the grinding disc, and the materials that meet the fineness requirements enter the finished product warehouse through the sorter.

Product advantages
1. Large output, high work efficiency, all accessories are independently produced by Xinxiang Great Wall Machinery.
2. The grinding roller bearing adopts the dilute oil circulation lubrication method, which can ensure that the bearing works at a lower temperature, and at the same time, the quality and purity of the lubricating oil are controlled, which is conducive to prolonging the service life of the bearing;
3. Equipped with a roll turning device, the grinding roller can be turned out of the grinding outside, which is easy to overhaul;
4. Compared with some other forms of roller mills, the hydraulic system of the vertical mill has low operating pressure, low oil leakage failure rate, and high safety and reliability;
5. The new high-efficiency cage rotor separator has high powder efficiency.
