Nickel Slag Vertical Mill

Process

The materials fall to the center of the grinding table through the blanking pipe, then the grinding table is rotating at a constant speed and disperses and spreads out the materials evenly with the aid of centrifugal force, which makes the grinding table become the material bed with a certain thickness. Then several grinding rollers on the grinding table grind and crush the materials at the same time. With the continuous centrifugal force, the materials constantly move toward the outer edge of the grinding table. When the materials that leave the grinding table meet the hot gas which enters the mill through the wind ring, the materials will also rise. Then the materials enter into the separator through the mill’s middle shell, during this process, the materials and the hot gas have sufficient heat exchange with each other, and the water is quickly evaporated. The powder separator controls the size of the finished products, particles that are larger than the specified size will be separated and fall back into the grinding table, and particles that meet the fineness requirement will enter the finished products warehouse through the powder separator.
