A WEG motor will drive the main mill of a cement plant in northeast Brazil
The grinding of the finished cement consumes approximately one third of the total electrical energy of a cement plant. Vertical Roller Mills (VRM) have a clearly higher energy efficiency than ball mills, even if the ball mill is combined with a roller press. This and further arguments

Sep 22, 2020 Overtaking cement grinding process limitations to reach full cement activation potential. The performance of conventional strength enhancers can be limited by different grinding process constraints. An example is given with a process design based on a combined high-pressure-roller-press with single chamber ball mill and 3rd generation separator.
The Cam Pha Cement project was initiated in 2003 by Vinaconex, Vietnam, aiming for a production capacity of 1.8 million tpa of cement. The project included the construction of two new plants: the main plant for the production of clinker, located in Cam Pha, Quang Ninh province, north Vietnam, and a cement grinding

MasterCem cement additives amplify grinding efficiency, resulting in a higher mill throughput and lower the clinker factor, with an overall reduction in CO2 emissions. Our performance enhancers modify and elevate cement’s properties, improving its strength, workability and flow and ultimately upgrading cement’s usability and durability.
A grinding aid is a specialty chemical agent used to make it easier to grind and mix cement. Specifically, grinding aids prevent cement particles from re-agglomeration, or re-adhering, during and after the grinding process. Grinding aids make it possible to streamline the cement-making process by increasing process efficiency and material fluidity.
Evaluated Suppliers. In CEMEX Procurement we strive to reinforce our suppliers’ awareness of specific policies that pertain to sustainability. We also work with third-party sustainability supply management firms that evaluate suppliers in terms of social, environmental, health and safety, ethical, and financial performance and provides ...
CHRYSO ICARE is a new patent-pending innovation that boosts cement compressive strengths to significantly reduce clinker factor and therefore cement CO 2 footprint. CHRYSO ICARE is a disruptive technology developed into 2 ranges:. CHRYSO ICARE CP for challenging grinding processes; CHRYSO ICARE VRM and Vertical Roller Mills
allows for a shortened cement retention time in the mill which, in the end, leads to significant energy savings for each ton of cement produced. • Maintenance cost reduction Shortened cement retention time in the mill leads to a less intensive use of the grinding system, therefore reducing mill maintenance cost per ton of cement.
Cement. Grinding aids have been traditionally used to improve the efficiency of the cement maturation process which is considered as one of the most energy consuming processes in cement production (60 - 70% of the total electricity consumed in the plant). They are usually added at the entrance of the mill together with the feed.
All cements had a content of 30% limestone. The parameters of mill and separator were adjusted to produce different cement surface (Blaine). An identical concrete mix (cement = 300kg/m 3, w/c = 0.60) was used to produce cubes which were subjected to the freeze-thaw test according to CEN/TS 12390-9. The concrete must have less than 10% loss of ...
shown that the usual grinding aids and also con-crete additives are well able to withstand normal grinding conditions. Appreciable decomposition is, however, possible if the cement is stored for weeks at above 50 C temperature. This can occur if silos are filled with hot cement. Mostly adsorption of grinding aids is revers-ible.
Process 4. Grinding additives. In order to improve quality of produced cement, it is supplemented with plaster for adjusting setting time and with active mineral additives (pyrites cinder, flue dust, bauxite, sand, gaize, tripoli) for improving certain properties and reducing the cost of cement.
