Component mass balance is performed around rotary kiln based on plant data that is presented in table 1. for this purpose, components such as iron, gangue, carbon and ash are considered for mass balance as these are the main components of feed material which is composed of iron ore, coal and dolomite.Get Quote
Mass balance is based onumber of user specified parameters as well as chemical relations found in the literature.eneral method to approach the different concentrations and mass flows when constructingingems block is also included in the report. in the energy balance the fuel consumption of the lime kiln is calculated.
