wet process of manufacturing of cement

Cement Extraction and processing BritannicaManufacturing the cement kiln Understanding 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 In the wet process the slurry tanks are stirred by mechanical means Wet process kilns The original rotary cement kilns were called wet process kilns In their basic form they were relatively simple compared with modern developments The raw meal was supplied at ambient temperature in the form of a slurry A wet process kiln may be up to 200m long and 6m in diameter
