Our modern vertical roller mill takes you further

The industry best in energy-efficient grinding the OK Mill uses five to ten percent less power than other vertical roller mills and 30 to 50 percent less energy than conventional ball mills. Easy operation and maintenance. Worn roller grinding surfaces can either be replaced or re-welded inside the vertical roller mill. Sixteen NSP kiln cement plants were surveyed regarding their cement production energy consumption and current adoption of 34 energy-efficient technologies and measures. Plant energy use was compared to both domestic (Chinese) and international best practice using the Benchmarking and Energy Saving Tool for Cement (BEST-Cement).

LOESCHE Vertical Roller Mill We do much more than rely solely on our unbeatable technology. Our designers are constantly coming up with new ideas and even more dependable components to reduce the already acclaimed low failure rate of our mills. Both energy and exergy efficiencies of the RM are investigated for the plant performance analysis and improvement and are determined to be 84.3 and 25.2 respectively. The present technique is proposed as a useful tool in the analysis of energy and exergy utilization developing energy policies and providing energy conservation measures.

ENERGY SCENARIO 4.1 Electrical Energy System The cement plant receives electricity supply from the Captive Power Plant (CPP) (12 MW) and DG sets. Industrial development has lead to higher energy consumption emission of greenhouse gases as well as air pollutants. Cement factories play an important role in over all greenhouse emissions. This study aims to investigate the role of Iranian cement industries and their contribution of greenhouse gases contribution. The measured emission factors for oil and fuel gas shows that carbon dioxide

Typical cement plant power costs can range from EUR39 to EUR170/MWh. Mill designs. The most important first step in controlling energy consumption is to be aware of the relative importance of the process areas where most energy is consumed. Figure 2 shows a typical breakdown of electrical energy consumption at a cement plant. • Power supply requirements and proposed energy conservation measures such as energy consumption during port activities pumping activities (e.g. sand reclamation) transport activities (e.g. delivery of raw materials transport of product) milling mixing pre-heating pre-

The results show that replacement of ball mills with vertical roller mill can reduce the electricity consumption from 44.6 to 28 kWh/ton. 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 led to the increased share of VRM for the grinding of finished cement. Taking into account that VRM usually have a bigger output than ball mills it can be declared that the major
