Cement mills and raw mills for high throughput rates

The required pressure forces are produced by a lever system comprising, among others, a roller arm, along with a hydropneumatic tension system. After being rolled over by the rollers, the material is conveyed to a stationary nozzle ring due to the rotation of the grinding table. Gases (air or hot gas) flow through this nozzle ring, take up the ground and dried material and convey it to the classifier where it
