12/05/2020 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.
Methods of Manufacturing Process of Cement. At present Portland Cement is manufactured by two processes, Dry Process, and Wet Process. The main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.

The main stages of cement production at a Portland cement plant are: Preparation of raw material Raw Milling – preparation of raw meal for the pyroprocessing system Pyroprocessing of raw meal to form cement clinker Cooling of cement clinker Storage of cement clinker Finish Milling Packing and loading.
Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore.

Well over three quarters of existing U.S. clinker production capacity has been built since 1975 -- all utilizing the dry manufacturing process. Currently, about 93 percent of the cement produced in the United States is manufactured using dry process technology.
Manufacturing of Cement In the manufacturing of cement, the following three important and distinct operations occur: Mixing of Raw materials.
Manufacture of Cement To manufacture cement first 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.

In dry and semi dry processes for manufacturing of cement, the raw materials are crushed and fed in the correct proportions into a grinding mill. The raw materials are dried and reduced in size to a fine powder in to grinding mill. The dry powder is called the raw meal. The raw meal is pumped into a blending silo.
The wet process of cement manufacturing refers to grinding raw material into slurry after mixing with water and then feeding them into the wet process kiln for drying and calcination and finally forming clinker. The slurry’s water content is usually between 32%-36%.
Fine ground raw meal is then stored and further homogenized in the raw meal silo. The heart of the cement manufacturing process is the thermal process in the kiln system with clinker capacities of up to 12,000 tonnes per day nowadays. A kiln system consists of a static preheating system with typically five cyclone stages and a pre-calciner.
