working principle. This vertical cement mill is widely used in the grinding of cement raw meal, slag (GGBS), cement clinker, raw coal and other raw materials. It gathers grinding, drying and powder selecting as a whole, with high grinding efficiency and high drying capacity ( the maximum handling material moisture is up to 20% ).
Vertical grinding mill uses the principle of grinding material layer material, low energy consumption, grinding system power consumption by 20% to 30% over the ball, and with the increase of raw water, energy-saving effect is more obvious. Vertical mill and milling system energy systems compared to savings of 30% to 40%.
The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time
Ball mills, that are commonly used for finish grinding, have high energy demands, consuming up to 30-42 kWh/t clinker depending on the fineness of the cement. Complete replacement of ball mills by vertical roller mills (VRMs) with an integral separator – as opposed to the use of VRMs as pre-grinding to ball mills – is regarded as a breakthrough.
Grinding of cement clinker in vertical roller mills is a technology introduced by LOESCHE, first used in 1935. Almost 40 years ago LOESCHE introduced the first vertical roller mill to grind cement clinker and granulated blast furnace slag in one process.
Process introduction The GRMK vertical cement mill of CHAENG adopts a new generation of cement grinding technology, which integrates grinding, drying and powder selecting functions.
