Reducing Energy Consumption Of A Raw Mill In Cement

Reducing Energy Consumption Of A Raw Mill In Cement

Jun 01, cement production in the world is currently about 1.6 billion ton per year. about 2% of the electricity produced in the whole world is used during the grinding process of raw materials .while total electrical energy consumption for cement production is about 100 kwh/ton of cement, roughly two thirds are used for particle size reduction .about 65% of the total electrical energy used in a cement.Jun 01, this paper aims to examine the size by mass distribution of each component around a closed circuit ball mill during cement production by intergrinding. for this purpose, a ball mill with an air classifier in a cement plant was sampled and size by assay analyses of the samples was carried out to calculate the particle size distribution of each.

Cement Cooling System

Cement Cooling System

The cooling of cement is an important step prior to storage in mitigating gypsum dehydration and subsequent moisture liberation which can lead to lump formation. recommendations vary but it is generally accepted that with mill outlet temperatures of around 110 c – 120 c, cooling to below 80 c is necessary to avoid this.The mill is designed to handle a total ball charge of 324.5 t at 100% loading with a percentage filling of 29.5% in both the chambers. both the chambers of the cement mill were charged with 80% of the designed charge, which works out to 86 t in ist chamber and 172 t in the iind.
