RAW MEAL SILOS IBAU HAMBURG Cement Minerals Thermal Red mud addition in the raw meal for the production of

IBAU raw meal silos are serve as a combined storage and blending silo The discharge technique of the IBAU CENTRAL CONE SILO simply creates a blending effectExpensive homogenising silos with a high power consumption are not required provided there is a sufficiently working preblending system for crushed limestoneThe red mud was mixed with other raw materials such as limestone schist Milos sand ironferous sand and bauxite in appropriate proportions in order to produce the raw meal to be tested for the production of Portland cement clinker PC R/M

CementHigh temperature cement raw meal flowability ScienceDirect

This ensures the raw meal enters the kiln at an approximate temperature of 900 176 C The material created at this stage is called clinker an intermediate product which constitutes the basis for cementThe results show that the raw meal sample can be categorized as cohesive in the range from room temperature to 550 176 C and as very cohesive/not flowing at 850 176 C This trend corresponds with practical observations in the cement industry suggesting that preheated or calcined raw meal flows more poorly than unheated raw meal
