The grinding system directly affects the quality of product cement. To produce high-quality cement is inseparable from the grinding station with reasonable design, reliable equipment, and careful maintenance. The dispersion of cement can be defined by the fineness and specific surface area of cement powders.
Crushing, grinding, drying and powder separating set-in-one, VRM can be used for grinding various materials of different moisture, nature and hardness to a required particle finesse. Therefore, it becomes ideal equipment in current grinding industry. INPUT:0-80mm. OUTPUT:80-325um. Application: For various types of non-metallic mineral grinding ...
o Energy consideration in cement grinding makes sense: it decreases production cost, increases output & reduces green house gas emission; o Proven technology available for both new & existing plant / equipment upgrade to generate attractive ROI; o Energy consideration should be regarded a basic responsibility
For the same reasons, the VRM is also developing as the preferred solution for cement grinding. This can be explained by issues such as cost of installation, ease of operation and maintenance, energy efficiency and product …
VRM has less flexibility in controlling particle size distribution. Overall ball miil is good option for Cement mill but only has limitations for higher capacity, as two ball mill to be installed for One VRM, but in case of breakdown one ball mill can be in operation. Trust this clear your clarifications on equipment selection for cment production.

Nigeria: Loesche has released details on its order for the United Cement Company of Nigeria (Unicem) cement plant at Mfamosing, near Calabar in Cross River State, which was commissioned in September 2016. The order was for two vertical roller mills (VRM): one type LM 60.4 for grinding cement raw material and one LM 70.4+4 CS, the biggest Loesche VRM …
To reduce and control emission, parallel bag house and bag filters have been installed in Satna complex. The Company has utilized 9,35,388 tonnes of flyash in 2008-09 alone, at its cement plants, thereby reducing clinker usage. This, in turn, has reduced GHG emissions at the plants, without compromising on the quality and strength of cement.
