Wet Process for Manufacturing of Cement

2021-4-22  The kiln has to operate continuously in order to ensure a steady regime, and therefore uniformity of clinker. The larger existing kiln in a wet process plant produces 3600 tonnes of clinker per day. The manufacture of cement by wet process is energy intensive and thus uneconomical as compared to dry process and semi dry process.
