Coal vertical roller mill is a machine that crushes and grinds coal into pulverized coal. It is an important auxiliary equipment of pulverized coal furnace.
The vertical mill is a horizontal cylindrical rotating device driven by external gears. Material from the feed device enters the mill evenly through the feed hollow shaft helix.
Installed with steel balls of different specifications, the centrifugal force generated by the rotation of the cylinder will bring the steel ball to a certain height and then drop, which will have a heavy impact and grinding effect on the material. The powder is discharged through the discharging grate to complete the grinding operation.
