PROFESSIONAL CEMENT PLANT OPTIMIZATION, MODERNIZATION AND ENERGY CONSERVATION . Dr. Hans Wilhelm Meyer & Marc Lambert . PEG S.A., Geneva, Switzerland . ABSTRACT . Optimization, modernization and energy conservation projects are on the daily topic-list of every cement plant operation and management.
Our best-in-class OK™ Mill is a globally successful vertical roller mill solution for grinding raw material, cement and slag. Its cutting-edge design features consistently deliver the highest quality products with the greatest efficiency. It is affordable to install and cost effective to operate over your cement plant's lifetime.
cement industry the ball mill was really an epoch-making breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding. Over the last three decades the vertical roller mill has become the preferred mill for grinding of raw materials.
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.

Volume 3, Issue 5, November 2013 388 hot-air furnace may be used to supply this heat, but usually hot waste gases from the kiln are used. For this reason, the raw mill is usually placed close to the kiln preheater. Ball mill is used in cement industry. After the dry chamber material enters the 1st grinding chamber. 1st grinding chamber:
4 Due to the interaction of raw materials and kiln gases, rotary kiln systems have inherent SO2 removal efficiencies ranging between 40-99% of the sulfur input to the system. The literature suggests that 50-70% of the remaining SO2 will be removed from exhaust gases when passed through an in-line raw mill system.
Figure 3.1: Typical Mimic sample of the Raw Mill Section 4. ENERGY SCENARIO 4.1 Electrical Energy System The cement plant receives electricity supply from the Captive Power Plant (CPP) (12 MW) and DG sets. It is distributed to various sections of the plant. An energy meter is installed on 110 kV feeder incomer, which records

The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time

The raw mix is fed into a circular storage unit called a raw mix storage. Then, the mix is extracted transversely from the stockpile by reclaimers and conveyed to a raw mill bin called the raw mix bin for grinding. The other raw materials that are used in cement manufacturing, called additives, are high purity limestone, sand and iron ore.
