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
Limestone • Cement producers usually locate their plants next to limestone deposits • Limestones of varying geological ages are distributed across the UK They vary considerably in their chemistry and thickness and their suitability for cement manufacturing • Carboniferous limestones are the major source of raw material in Britain
How is Steel Produced? Global steel production is dependent on coal 70% of the steel produced uses coal Metallurgical coal – or coking coal – is a vital ingredient in the steel making process World crude steel production was 18 billion tonnes in 2018
result will be lower consumption of raw materials, reduced specific energy consumption, good furnace operation, higher alloy quality and lower production cost Thus, it is of prime importance to examine the different parameters affecting on the production of high ,

ENERGY USE IN THE STEEL INDUSTRY Most steel products remain in use for decades or even centuries before their function is no longer needed and they can then be reused, remanufactured or recycled Therefore, there is not enough recycled steel to meet growing demand Demand is met through a combined use of the BF-BOF and EAF production rout
It is clear that there are five stages in the production of cement, beginning with the input of raw materials and ending with bags of the finished product To produce concrete, four different materials are mixed together At the first stage in the production of cement, limestone ,
Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln
