These consist of a pair of rollers set 8–30 mm apart and counter-rotating with surface speed around 0.9 1.8 m.s . The bearings of the rollers are designed to deliver a pressure of 50 MPa or more. The bed of material drawn between the rollers emerges as a slab-like agglomeration of highly fractured particles. The energy efficiency of this process is comparatively high. Systems have been designed, including a de-agglomerator and separator, that will deliver material of cement fineness. However, particle size distrib

Cement Grinding. In the final manufacturing stage, gypsum is measured and added to the clinker in order to yeild the final product. After first passing the mixture through a roller press, it is further reduced into a fine powder with the help of a single chamber ball mill. Learn More
Drying chamber elements For the drying chamber of raw mills. Drying chamber elements are used in raw mills, where a pre-drying of the feed material is required. Their function is to pick up the moist feed material and to transport it into the hot gas airflow. This way an effective drying of the material is achieved. Read more
