Cement kiln dust (CKD) is the same as what is called "fly ash" in trash incinerators or coal power plants. Recycling of CKD into cement adds toxic metals to the cement. "In 1990, on average 9 tons of this cement kiln dust (CKD) was produced for every 100 tons of clinker."

The utilisation of coal in the cement and concrete industries takes three basic forms: 1. As a fuel in the production of cement clinker, 2. Ash produced by burning coal in power stations is used as a component in cement rotary kiln feeds, 3. Ash produced by burning coal in power stations is used as a mineral additive in concrete mixes.

The material formed in the kiln is described as 'clinker' and is typically composed of rounded nodules between 1mm and 25mm across. After cooling, the clinker may be stored temporarily in a clinker store, or it may pass directly to the cement mill. The cement mill grinds the clinker to a fine powder.

COAL HANDLING SAFETY Risks of unwanted combustion – potentially causing injury, damage and downtime – occur everywhere that coal is handled, processed or stored. Safe coal handling practices are designed to ensure that the fuel remains intact throughout its journey from the mine until the point at which it is ignited in the boiler.

Coal Mills for Cement Plants. Coal grinding mills LOESCHE coal grinding mills are distinguished by characteristics that improve efficiency, safety and environmental protection, from the standard version to top-of-the-range installations.

Normally, the entire requirement of PA flow necessary for a particular load at the mill is initially attempted through HAD so as to ensure complete drying of the coal (especially during rainy seasons) and to raise the mill temperature at a desired point. However, there may be times during hot dry summers when the mill outlet temperature shoots up.

VG: At best, coal mill safety is not well understood and, at worst, it is ignored. When it comes to coal mill systems, most cement plant operators just presume that the supplier of the equipment knows all of the standards and rules and is capable of making a system that conforms to these and is therefore safe. However, this is not the case.

Coal mill is also called coal pulverizer or coal grinder. It is a mechanical device used to grind raw coal into pulverized coal powders. The most used coal mills in cement plants are air-swept ball mill and vertical roller mill.. At present, most cement plants use coal as the main fuel in the clinker production process.

Despite the use of oil and gas in many regions and the rapid rise of alternative fuels, coal remains the major cement production fuel. It must be safely handled when ground and fed into the kiln and, even though it is a difficult topic to broach, the onus to have the conversation is on the cement producer.

Coal Feeder is a device that regulates the amount of coal to be supplied into the Coal Mill. The amount of coal is regulated according to the needs in the boiler combustion chamber (furnace). The number regulation system in the coal feeder can be done in two ways based on the type, namely by weight fraction or coal volume fraction.
