with other supplementary cementitious material (SCMs). The cost of limestone raw material (~ 4/t ) is also considerably lower than Portland cement clinker (~ 25/t) while limestone processing emits far lower CO 2 volumes than clinker. In addition, limestone as a clinker replacement can increase plant output in a …
Cement production process typically involves (i) grinding limestone (and other raw materials to achieve the right chemical composition) to about 90% passing 90 μm screen in a dry circuit, (ii) making cement by the chemical reaction between the components of the ground mixture. This chemical reaction occurs at high temperature in a rotary kiln.

A method and system for desulfurizing flue gas in which desulfurization is effected by bringing absorbent slurry containing limestone into contact with flue gas. The method classifies absorbent slurry extracted from a desulfurization absorber, returns a fine-side fluid to the desulfurization absorber, and sends a coarse-side fluid to a solid-liquid separator.
A silicate cement clinker containing anhydrous calcium thioaluminate mineral is prepared from lime stone, clay and mineralizing agent through proportioning, grinding and calcining. It contains C3S, C2S and C4A3S. Its advantages are high strength and antiflex cracking rate, and high compatibility with powdered coal ash.
