What is Portland cement process of Manufacturing,Dry and Wet

Portland cement is two processes, known as ‘wet’ or ‘dry’ processes depending upon whether the mixing and grinding of materials done in wet or dry conditions. A wet process was popular in the early years because of the possibility of more accurate control in the mixing of raw materials. The nowadays dry process is much popular because the dry process required less fuel than the wet

Cement: Materials and manufacturing process

• Chalk is porous and often has high moisture content that leads it to its use in the ‘semi-dry/wet’ manufacturing process of making cement. This particular process represents some 16% of total production. Shale • Shale is a pure sedimentary rock made of very fine silt, clay and quarz. Shale falls in the category of mudstones. Its grain

DETAILED DRY PROCESS OF CEMENT MANUFACTURING

In dry and semi-dry processes for the manufacture of cement, raw materials are crushed and fed into the grinder in the correct proportions. The raw material is dried and reduced in size to a fine powder in a grinder. Dry powder is called a raw meal. Raw meals are pumped into mixing silos. Adjustment of the proportions of materials required for cement manufacturing is made in silos.
