Wet process of cement

Wet process

There are two different processes of manufacturing cement. wet process minerals are wet ground (by adding water) to form a slurry and then dried, dry process minerals are dry ground to form a powder like substance.Both the processes are in use and have their own advantages and disadvantages.While in wet process grinding is easier,in dry process there is a saving in fuel costs involved in drying up the slurry.

  1. Mixing of Raw materials in wash mill with 35 to 50% water.
  2. Materials exiting the mill are called “slurry” and have flow-ability characteristics.
  3. Size of the kiln needed for manufacturing of cement is bigger.
  4. Raw material can be mixed easily, so a better homogeneous material can be obtained
  5. Fuel consumption is high i.e., 350 kg of coal per tonne of cement produced.
  6. Cost of production is high.
  7. Capital cost (Cost of establishment) is comparatively less.
