High efficiency ball mill for cement grinding news date:2015-12-08 10:14:49. high efficiency cement ball mill is mainly used in grinding raw materials and final products in cement plant. it is also suitable for grinding various ores and other materials in chemical metallurgy and power industry and so on.
In the cement production line producing 1 ton of cement need grind at least 3 tons of materials including raw materials fuel clinker mixed materialsgypsumgrinding operation consumes about 60 of total power in cement plants raw material grinding more than 30 while coal mill used in cement plant consumes 3 cement grinding about 40.
In this study certain measures are implemented in an existing raw mill in a cement factory and the specific energy consumption of the unit is calculated to be 25.52 kwhton farine.
In this study the first and second law analysis of a raw mill is performed and certain measures are implemented in an existing raw mill in a cement factory in order to reduce the amount of energy consumption in grinding process. the first and second law efficiencies of the raw mill are determined to be 61.5 and 16.4 respectively.
Indian cement consumption is 11.19 compared to china’s cement consumption for that year. 1.2 motivation. economic growth and energy consumption are very closely related non availability of energy and material will have a downfall on the country’s economic growth. energy demand in industries are increasing to 0.5 per year.
Introduction : vertical raw mill is a type of industrial equipment used to crush or grind materials into small particles.vertical roller mills are widely used in the concrete and mining fields and are also used to process gypsum. these units can process both raw and recycled materials while helping to reduce waste and preserve virgin supplies of these materials.
