Cement Cement Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.
The raw materials needed to produce cement (calcium carbonate, silica, alumina and iron ore) are generally extracted from limestone rock, chalk, clayey schist or clay. Suitable reserves can be found in most countries. These raw materials are extracted from the quarry by blasting. They are then crushed and transported to the plant where they are stored and homogenized.

Calcareous materials containing limestone or chalk and argillaceous materials containing an oxide of silicaalumina and iron are found as clay or shale.
Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the ''raw feed'' or ''kiln feed'' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.
Overall, there are six steps in the cement making process and concrete production is comparatively easier as it involves combining the right proportion of different ingredients.According to the first diagram, limestones and clays are two essential raw materials for the cement making process. They are put on a crushing machine and turn into powder.
Success Formula for Flyash Brick Mixing Ratio. For manufacturing flyash bricks, most of the machine manufacturers suggest the following TWO mixing ratio, YOU CAN CHOOSE PROFITABLE MIXING RATIO TO SURVIVE IN THE MARKET if you are facing low availability of Flyash.. At the same time you should maintain the quality too.
Secondary raw materials (materials in the raw mix other than limestone) depend on the purity of the limestone. Some of the materials used are clay, shale, sand, iron ore, bauxite, fly ash, and slag. When a cement kiln is fired by coal, the ash of the coal acts as a secondary raw material. Cement grinding
Portland cement accounts for more than 95% of all cement produced. To make Portland cement, clay, shale and limestone is ground to a powder and baked in a kiln. The baked mixture forms clods (clinkers), which are then ground up and mixed with gypsum. Most of the raw materials are mined in open pits. Michigan traditionally ranks in the five
