Wiser with analysers. Dr.-Ing. Roger Meier, FCT-ACTech, explains why online analysers should form part of every cement plant's CO 2 emissions reduction strategy. The new buzzwords and phrases worldwide include 'energy transition', 'CO 2 reduction' and 'sustainability', and these are all heavily used by the energy intensive industries.

introducing alternative fuels and raw materials into a standard cement production process, rather than using conventional fuels and raw materials. A cement kiln producing clinker (the main constituent of cement), is by its nature an efficient tool for the recovery of minerals and energy from waste. Below are some reasons why.

In addition to the work carried out at our specialist research facility in Dania, we have learned by doing.

The use of alternative fuels in both combustion and production processes is known as co-processing in cement manufacturing. Waste is now being used to substitute primary fuel sources like coal, petroleum, and gas in the combustion process. They are usually from combustible municipal waste, refuse-derived fuels, biomass, or non-hazardous industrial and commercial waste.

The milling process in cement plants is extremely energy-intensive. there are potential energy savings available through the use of Mill Control System (MCS). The MCS is a software system that draws conclusions about the quality levels of the production plant through a knowledge-based approach using current plant data (defined measured values).

Alternative cementing materials can directly replace a portion of portland cement. These materials can be used alone or blended with other alternative cementing materials to produce a cement or concrete with properties different than those resulting from the use of portland cement.

Let us take the cement industry first. One of the key solutions here is finding alternative fuels. Producing cement is a very energy intensive process, demanding substantial energy to reach the heat needed for the processes involved. The combustion of fuels counts for …

viii Increasing the Use of Alternative Fuels at Cement Plants: International Best Practice Cement is paramount for economic development and poverty reduction in emerging markets. Along with aggregates and water, cement is the key ingredient in the production of concrete, and, as such, is an essential construction material

Cement milling and gypsum dehydration Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris - 2CaSO 4 .H 2 O. On further heating, hemihydrate dehydrates further to a form of calcium sulfate known as soluble anhydrite (~CaSO 4 ).

alternative raw materials, however these materials are still referred to as "wastes" in cement sector and other industry sector documents. For example, the Portland Cement Association (PCA) Annual Labor and Energy Report . 1. refers to "waste, oil," "waste,

The cement grinding process in the ball mill generates a relatively broad PSD. Typical slopes are in the range of about 0.8 to about 1.0 on the RRSB granulometric diagram if the ball mill is operated in a closed circuit with a separator. The cement fineness can be adjusted by the selected fresh material feed, the rotational speed of the ...

6. Cement milling Finish milling is the grinding together of clinker with some 3-5 per cent gypsum, natural or synthetic, for set control, and quite often other components: blastfurnace slag, pozzolan, silica fume, limestone or pulverised fuel ash ('pfa' – also known as 'fly ash'). The process and equipment circuits are similar to those

ALTERNATIVE FUELS, or sometimes referred to as SECONDARY FUELS, are one of the main issues of modern cement production. Firing waste materials of any kind with calorific burning value began in Europe and Japan during the mid of 1980s and meanwhile the entire world, including developing countries, is placing great emphasis on this matter.

Alternative fuel materials used in the production of cement, can come in a wide variety of thicknesses, shapes, coarseness and types.
