Mill (grinding) - Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().Drives for large vertical roller mills - Cement Lime GypsumIn the period 2009 to 2015, of the 1209 new mills that were ordered by the cement industry outside China, 661 units or 55 % were VRM, the remaining 45 % were other types such as ball mills, high-pressure grinding rollers (HPGR) and horizontal mills. Figure 1 shows how the mill market potential developed and how the market share of VRM changed.): Automation solutions for the Cement Industry.Automation and Drives (A&D) is one of the largest groups within Siemens AG. As a technology and market leader in automation and drives technology, we are continually driving forward progress in this field – and setting new standards again and again. Siemens A&D offers a unique, complete range of innovative products, systems and solutions.Rating Of Cement Mill Electric DrivesSiemens MultiDrive System Powers Holcim Mill. The Siemens Drive Technologies Division has developed a new drive system for a cement mill as part of a joint project with Gebr. Pfeiffer SE. With an overall power rating of 11,500 kW and producing 450 metric tph of cement, the vertical mill is the most powerful of its kind in the
