Vertical Mills. A significant portion of the cost to produce a ton of cement resides in the grinding costs. The industry standard for decades has been horizontal ball mills which rely upon heavy balls cascading inside a fast turning mill to crush the clinker into the fine cement powder. This process is energy intensive and the balls require considerable, high-labor maintenance. McInnis has

Vertical Mills. Vertical mills (such as bowl, roller grinding, ball-and-ring, and roller mills) are mainly used for comminuting limestone, clinker, slag, lime, gypsum, and ores for the building industry, and coal in the coal preparation. They reduce raw material from a thickness of 30 mm to a very fine-grained material. The pulverizing of mineral raw materials is an extraordinarily energy-consuming process. To make

Vertical cement mills are able to reach production values which are significantly higher than the ones achievable with traditional ball mills, in some cases up to 300 t/h. Empirically, It can be estimated through a simple heat balance that in ball mills only 10% of the energy is used to increase cement fineness, the rest being dissipated basically in form of heat. A VRM allows the exploitation
