It takes about 200 kg of coal to produce one tonne of cement and about300-400 kgof cement is needed to produce one cubic metre of concrete. Coal combustion products (CCPs) , such as Fly Ash also play an important role in cement manufacture and in the construction industry generally.
A rotary kiln is a device that supplies tremendous amounts of heat in order to change the chemical composition of an object.
A cement mill is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.
The hammer crusher, also named heavy hammer crusher, crushes by the collisions between high-speed hammer and materials. It has features of simple structure, high reduction ration, high efficiency, etc.
Hongxing rod grinder is especially suitable for crushing river gravel to make sand. It's a kind of effective and energy saving rod grinding machine.
Raymond mill adopts advanced structure of the same types of products in domestic and foreign market and is upgraded and improved on the basis of traditional Raymond mill.
The dryer machine has been mainly used for drying materials with some humidity and granularity in the fields, such as ore dressing, building materials, metallurgy, chemical industry, etc.
Furthermore,coal, which is conventionally used forcombustion, is increasingly being replaced by alternative fuels like Municipal solid waste (MSW), rubber tires, dried sewage sludge, etc. In fact, it is theindustry’s best-kept secret thatcement kilnsare the last and best resort for recycling almost any waste produced in human societies.
Coal Usagein theCement Industry AusIMM Pulverised coal firingwas pioneered in the cement industry prior to the turn of the century. Ash from the coal is absorbed into the mix in the kiln and replaces secondary materials. With high purity limestone coal with high ash content can be used.
