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 is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
TOWARDS A BETTER UNDERSTANDING OF STIRRED MILLING TECHNOLOGIES ESTIMATING POWER CONSUMPTION AND ENERGY USE ... the VERTIMILL® grinding mill has been cited in a couple of papers (Nesset et al., 2006; Mazzinghy et al., 2012) as being some 35% to 40% more efficient than ball mills for fine ... Towards a Better Understanding of Stirred Milling ...
Grinding technology has been continuously improving with numerous innovations with a view to improve productivity and reduce power consumption. In order to reduce the manufacturing costs for cement, it is very important to optimise the existing mill installations as far as the grinding .

HLM Series vertical roller mill is a kind of advanced mill developed by Hongcheng based on two decades of RD experience and introduction of foreign advanced technology. It features in a combination of drying, grinding, classifying and conveying. HLM vertical grinding mill, has high grinding efficiency, low power consumption, large feed size, product fineness easy adjustment, equipment process ...
A finite element model of the planetary wheel coalbed was built up by the use of a rigid and a DruckerPrager material model in LSDYNA. According to the simulation results, the wheel rolling resistance, the grinding power consumption and the motor power of the mill were calculated and the mistake in the initial design of the mill was modified.
Below is a typical HP/ton consumption chart based on our experience. However, keep in mind that power consumption varies with mill types but are also largely influenced by coal feed rate, HGI variations, spring pressures, coal fineness, mechanical alignment of the grinding elements, bearing condition, optimum or reduced air/fuel ratios, etc.
by Erdem (2002) for dry multicomponent cement grinding ball mills, using the results of the Bond ball mill grindability test. For all model based methods, a reliable method to calculate mill power draw for a given mill is required for the calculation of power draw. Morrell (1996) proposed a

ore grinding. POLYCOM® for cement finishgrinding. The POLYCOM can be used as machine component in finishgrinding systems or it can be used as an independent finishing mill. The larger the amount of grinding work performed by the POLYCOM®, the greater is the reduction in power consumption. Modern and userfriendly equipment for
This type of mill offers the minerals industry numerous benefits: Safe process technological design. Low operating expenses: in comparison to other systems, both the power consumption and the costs for wear parts are significantly lower. High throughput rates: a highpressure grinding roll can replace several reduction crushers.
