cement manufacture process

Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln.

Oct 29, 2019· The cement manufacturing process involves several key steps, including preparing the raw materials, grinding the materials together, heating the newly formed clinker in a kiln, and finishing the cement with fine grinding. Some of the main ingredients used to make cement include limestone, clay, shale, iron, and sand.

ManufactureofCementTomanufacture cementfirst of all limestone is added into the clay in proportion of 3:1 by weight. This mixture of limestone and clay is then dried and crushed to get a fine powder called ‘raw meal’.The raw meal is then added into a rotary kiln through a hopper as shown in figure.

ManufacturingofCementBy Dry and WetProcess ManufacturingofCementIn themanufacturingofcement, the following three important and distinct operations occur: Mixing of Raw materials. Burning Grinding Theprocess, by whichcementis manufactured, depends upon the technique adopted in the mixing of raw materials.

From the limestone quarry to the delivery of the end product, follow every step in thecement manufacturing process. Step 1: extraction of raw materials The raw materials needed to producecement(calcium carbonate, silica, alumina and iron ore) are generally extracted from limestone rock, chalk, clayey schist or clay.

Thecement manufacturing processstarts from the mining of raw materials that are used incement manufacturing, mainly limestone and clays. A limestone quarry is inside the plant area and a clays quarry is as far from the plant area as 25 km.

Portland cementcan be made by following two different processes – a dry one and a wet one. Joseph Aspdin first madeportland cementin his kitchen stove in England in the 19th century. Lime and silica make up approximately 85% ofportland cement. The materials that are commonly used are limestone, shells, chalk, shale, clay, slate, silica sand, and iron ore. Since limestone is the main ...
