Generally speaking, Grinding of clinker is the last and most energy-consuming stage of the cement manufacturing process, drawing on average 40% of the total energy required to produce one ton of cement. During this stage, the clinker particles are substantially reduced in size to generate a certain level of fineness as it has a direct influence on such performance characteristics of the final product as rate of hydration, water demand, strength development, and other. The grinding objectives tying together the energy and fineness requirements were formulated based on a review of the state of the art of clinker grinding and numerical simulation employing the Markov chain theory.

Common clinker mineral as follow:
Cement mineral for construction industry
Limestone (purity not less than 88% Total Carbonate)
Clay ( Black Soil ) should be buttery
Coke Breeze / Petro Coke
Laterite ( Used if Clay do not have 16% Fe2O3)
Gypsum (Additive used during Clinker Grinding)

Cement is a common construction material; a binder in mortars and concretes that hardens in the presence of water. Cement is called hydraulic cone crusher hpc when the hardened product is stable in an aqueous environment. The most widespread hydraulic cement today is portland cement – a finely ground gray-to-white powder composed primarily of calcium silicates, calcium aluminates, and calcium ferrites, derived from mineral ingredients.
