Dec 12, 2016· Minerals of natural origin as well as industrial products can be used for the production of cement. Starting material for this purpose are mineral compounds containing the main components of cement: lime, silica, alumina and ironoxide. Seldom are these components present in the needed proportion in one raw material.
The European Commission''s objective is to promote, within the context of the EU''s wider industrial policy, the competitiveness of industries related to raw materials. These industries are represented by metal industries, nonmetallic minerals industries, minerals and nonenergy extractive industries and forestbased ...
The proper use of alternative fuels and materials in the cement industry is essential for the planning and promotion of different methods that can decrease the environmental impacts, lower the consumption of energy and material resources, and reduce the economic costs of this industry.
Raw materials used for manufacturing of Portland cement are found naturally in the earth crust. It is made primarily from calcareous materials, argillaceous materials and gypsum. Calcareous materials containing limestone or chalk and argillaceous materials containing an oxide of silicaalumina and iron are found as clay or shale.
Aug 30, 2012· Raw materials are extracted from the quarry and by means of conveyor belt material is transported to the cement plant. There are also various other raw materials used for cement manufacturing. For example shale, fly ash, mill scale and bauxite. These raw materials are directly brought from other sources because of small requirements.
A cement plant consumes 3 to 6 GJ of fuel per tonne of clinker produced, depending on the raw materials and the process used. Most cement kilns today use coal and petroleum coke as primary fuels, and to a lesser extent natural gas and fuel oil.

The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 80–90% of raw material for the kiln feed is limestone. Clayey raw material accounts for between 10–15%, although the precise amounts will vary. Magnesium carbonate, which may be present in limestone, is the main undesirable impurity. The level
Short routes for supply of raw materials take pressure off of traffic volumes and reduce transportrelated emission of pollutants. Procurement of natural raw materials will continue to form the basis for cement manufacture in future. Use of alternative raw materials can be further increased to a certain extent.

Raw materials for cement manufacture. Materials used in the Cement Industry in Britain and Ireland. Almost any mineral can be used in a cement rawmix, provided that the bulk composition of the mixture will produce the desired calcium silicates and fluxes (see clinker), and provided that certain deleterious components are speaking, minerals containing high levels of calcium ...
Raw materials used in cement manufacturing. If you happen to be a geologist, the raw materials quarry is probably the most interesting part of a cement works, maybe unless you view the clinkering process as igneous rocks in the making.
The raw materials needed to produce cement (calcium carbonate, silica, alumina and iron ore) are generally extracted from limestone rock, chalk, clayey schist or clay. Suitable reserves can be found in most countries. These raw materials are extracted from the quarry by blasting. They are then crushed and transported to the plant where they are stored and homogenized.
Aggregate Industry. Aggregates are building materials used in construction, including sand, gravel, crushed stone, and recycled concrete. Aggregates are mined and either used in their raw form (for example, as foundations) or serve as composite materials in the production of concrete and asphalt.
