2021-6-14 There are two basic homogenizing processes for dry raw meal i.e. Batch process and continuous process. In the batch process, at least two pairs of double deck silos, each consisting of a blending silo at the top and a storage silo below are used. Sequence of operation of the silo i.e. filling, blending and storing is made independently.

re Impact of ALKALY, SULPHURE and CHLORINE in Kiln operation and clinker quality ? Hello Sir, Yes our Rawmeal chloride has increases from 0.22 to 0.28 %, but we r maintaining this with 45 % bypass rate, our bypass system is designed for 50 %, and 0.3 Cl %, I not observed any disturbance in kiln operation , but only my clinker lime has gone down to 65.5 %, our target is 66 %.
