Clinker grinding is the stage in which the final product stage in cement production ,it is independent of each other. in this stage, the cement clinker is added with an appropriate amount of the mixed material ,it is be ground to produce finished cement. the electric motor drives the disc through the reducer, and the hot air enters the vertical.
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 airswept ball mill and vertical roller mill.. at present, most cement plants use coal as the main fuel in the clinker production process.
Feeding the cement mill with materials previously considered waste, such as fly ashes, blast furnace slag, noncalcined limestone or silica sands, alongside the clinker, would lead to reductions greater than 10 in each impact category when reducing the clinkertocement ratio from 0.8 to 0.7 (garc agusano et al., 2014). replacing fossil.
Clinker size and cement grinding. for most mill systems, manufacturers recommend the following raw material size: fine clinker is more of an issue in vertical roller mills, since it can quickly slip under the rollers, leading to vibration and instability. as a general rule, there should be less than 25 of clinker that is below 1mm in size.
In the cement manufacturing process, raw mill in cement plant grind cement raw materials into the raw mix, and the raw mix is sent to the cement kiln to make cement clinker, next, clinker and other admixtures will be ground into finished cement by cement mill.
