Cement grinding Vertical roller mills VS ball mills
For ball mills grinding OPC to a fineness of up to around 3600 cm2/g (Blaine) grinding aid is usually not required; it may not even be feasible considering the cost of grinding aid However, a vertical roller mill for cement grinding generally requires the use of grinding aid to achieve the most efficient operation with a stable grinding bed It is suitable for replacements of existing vertical mill drives CONCLUSION With the trend towards large single VRMs for raw material and cement grinding the reliability of the drive systems are only becoming more critical Many competing drive technologies have been developed with the focus of increasing reliabilityDrive Systems for Vertical Roller MillsWhether grinding raw coal, clinker, cement and/or slag, we have a VRM solution to suit your grinding needs What’s more, our online condition monitoring services enable you to adopt a proactive maintenance strategy for your OK™ and ATOX® mills that eliminates unexpected downtime and ensures continuous high performanceVertical roller mills FLSmidth CementDelivering up to 3000 kNm torque, David Brown Santasalo vertical roll mill drives provide the optimum solution for grinding applications Developed in cooperation with roller mill manufacturers, our vertical roll mill gearboxes combine strength Vertical Mill Roller Drives dbsantasalo
