6. Cement milling Finish milling is the grinding together of clinker with some 3-5 per cent gypsum, natural or synthetic, for set control, and quite often other components: blastfurnace slag, pozzolan, silica fume, limestone or pulverised fuel ash ('pfa' – also known as 'fly ash'). The process and equipment circuits are similar to those

Slag cement, originally known as granulated blast-furnace slag, begins with the production of iron. The heart of the process is the blast furnace that refines iron ore into iron. The ingredients are heated to nearly 1500 degrees Centigrade to form two components: iron and molten slag. The iron is used to produce steel, and the molten slag is ...

The milling process generates heat and excessive mill temperatures are undesirable. It is clearly helpful, therefore, if the clinker is cool as it enters the mill. From an environmental and a cost viewpoint, the cooler reduces energy consumption by extracting heat from the clinker, enabling it to be used to heat the raw materials.

These additives, along with the limestone, are fed from bins to the raw mill. An extremely important step in the cement process is to proportionally feed these materials to the raw mill to ensure the correct "blend" of these materials. One can think of this process as a "recipe" for making various types of cement.
