PROCESS DIAGNOSTIC STUDIES FOR CEMENT MILL OPTIMISATION - CASE STUDY V.K. Batra*, D. Bhaskara Rao** and Raju Goyal*** Holtec Consulting Private Ltd., New Delhi ABSTRACT Grinding technology has been continuously improving with numerous innovations with a view to improve productivity and reduce power consumption.
The grinding of raw material of cement manufacturing has broad effect on the homogeneity of feed raw material into rotation clinker furnace. Due to the effect of particle size distribution of raw material on melting and chemical reaction of clinker mixture, the grinding procedure was widely studied (Pilevneli et al., 2004, Jankovic et al., 2004).
Dec 08, 2009· Re: high vibration of vertical mill for raw material. The vibrations of VRM are mainly due to the unstable bed and improper compaction. You can try water spray to compact the bed. Also please ensure whether the mill feed rate is uniform. In case any other clarifications, please contact "ms@madrascements. " Reply

Description of vertical roller mill for cement grinding:
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
Feb 23, 2016· Raw mill fans: Raw mill fan in cement industry carries gas and raw meal. The pressure drop in raw mill fan is very high. If a vertical roller mill is used for raw grinding in cement industry then a large raw mill fan is installed. Usually cement industries use centrifugal fans to carry out this process. 4.
Preparation of cement raw materials. Alite (approximately Ca 3 SiO 5) provides almost all the "early strength" (strength up to seven days of curing) of cement and a moderate amount of late (>7 days) strength. Belite (approximately Ca 2 SiO 4) provides very little "early strength" and a large amount of late strength.So it can be seen that these small compositional changes have a large effect ...
Raw material ball mill. ... it will inevitably lead to the damage of some accessories in the vertical mill, so the vibration of the vertical mill must be strictly controlled in the production process. ... If the wind temperature is too high, it can achieve a good drying effect and grinding effect, but it will cause the material layer to be too ...
Mar 01, 2016· re vibration vertical roller mill. There are a number of reasons for high vibrations in vertical roller mills, such as: 1. Failure of the grout or cement material under the steel beams embedded in the foundation top, which allows oil to penetrate, further degrading the concrete.
Technical Notebook CEMENT ADDITIVES FOR VERTICAL MILLS. RESEARCH & DEVELOPMENT ... 3.2 HOW DOES A VERTICAL MILL WORK? The raw materials are fed directly to the centre of the grinding plate, which, thanks to centrifugal forces and the pushing effect of the incoming ... the cement by: • Reducing the vibration levels of the grinding plate
Vertical roller mills Vs ball mills has long been a raging debate in the cement industry. In spite of the fact that vertical roller mills have been around for over ten years now and have gradually become the standard as far as cement manufacturing goes, several cement manufacturers still prefer ball mills for cement production [.]
