Vertical roller grinding mills for grinding • Coal • Cement raw material • Clinker granulated slag • Industrial minerals, and • Ores The core elements of these plants are the Loesche vertical mills for dry grinding the above mentioned grinding stock. Loesche has developed and built the largest and most.However, finishing grinding in the cement production process requires accurate temperature control. To achieve this, Vertical Roller Mills burn fuel to heat the mill interior before grinding initiates. In this paper the fuel cost of reheating a vertical roller mill after an evening load reduction event is compared to the electricity saving gained.
Grinding of cement clinker in vertical roller mills is a technology introduced by LOESCHE which was first used in 1935. Almost 30 years ago LOESCHE introduced the first vertical roller mill to grind both, cement clinker and granulated blast furnace slag, in one process.The vertical roller mill (VRM) is firmly established in cement plants all over the world. The biggest issues facing plants are not due to the equipment itself, but to do with how well mill maintenance is understood and how the mill is looked after following commissioning.
