Impacts of Clinker Storages Heat Transfer, Its Effect on Vertical Roller Cement Performances: A Case Study of Cement Grinding Operations in Nigeria

Operational data indicates that vertical roller cement mills (VRCM) consumed lesser energy when compared to horizontal/ball mills. A case study of a was carried out in Nigeria which experiencing lower production output and higher consumption. This research investigate reasons behind the low on VRCM. thorough analysis clinker storage facilities heat transfer across composite cylindrical silo walls (off – spec main clinker) both silos having same design but with different dimensions application purpose. The off-spec has capacity 1,800 tons 60, 000 stores hot left kiln cooler at approximate temperature 95oC. analytical results shows rate 728 kW 217.15 kW. Numerical simulation also using ANSYS package obtained were good agreement theoretically. ratio loss 3.35:1.
