its calculation A new cement plant during construction consumes a large quantity of refractories As a rule of thumb a cement plant consumes the same tonnage of refractories equal to its rated capacity in tons per day which means a 6000 TPD cement project consumes about 6000 tons refractory Proper quality control of the procured.
The refractory lining is from 6 in 152 cm to 10 in 254 cm thick Production capacities for these units range from 50 tonsday of CaO 45 metric tonsday to 450 tonsday of CaO 400 metric tonsday The weight of the kiln is supported on riding rings that encircle the kiln.
