Veettelschoss, Germany - Vertical roller mills have gained a firm footing in many branches of industry for size reduction of bulk materials. Typical applications are in power plants and in the cement industry. Like all other bulk material handling and processing equipment, vertical roller mills are subject to considerable wear. Typical zones of wear include material feeding, the mill housing, the grinding tools and the integrated separating systems and material discharge. To ensure high grinding quality and continuous trouble-free operation, optimal lining materials have to be used in the different mill areas. Time-proven materials of great hardness that provide appropriately long periods of use are, for example, the various materials offerned by Kalenborn Kalprotect.
