Portland cement clinker - overview

Portland cement clinker - overview. Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. This page gives a thumbnail sketch.

Simple Input Method (A1) - LOI of Raw Meal

Simple Input Method (A1) - LOI of Raw Meal. The simple input method (A1) is in principle based on the determination of the loss on ignition of raw meal (LOI Loss on Ignition RM, uncalcined).The loss on ignition of the kiln feed (LOI kiln feed) can be used instead of LOI RM, as long as the dust return is not significantly calcined (degree of calcination: d<5%) and contributes with less than 20% ...
