Vertical roller mill for gypsum, dolomite, feldspar, talc, limestone powder production can also be used in cement industry.
Final grain size: 2500 mesh (5 micron) to 15 mesh (1 mm).
CLIRIK vertical roller mill is the best choice for your cement plant.
Over View of cement vertical roller mill:
To make the different ingredients into products of a certain granularity, in order to get required size for clinker calcinations.
Smaller size particular has larger surface area to be completely contacted with each other, bringing fast chemical reaction, which is good to make clinkers of high quality.
When the degree of grinded raw material is too high, it has no obvious positive impact for calcinations, but costs too much electricity. So you have to control the grinded particular finesse in a reasonable range.
The best suitable finesse and granularity: 1.0-1.5% of grinded particular under 0.2mm, 8-12% under 0.08mm
Vertical roller mill benefits:

1. 20-50% less energy use than ball mill systems
2. For portland cement, slag and blended cements
3. High productivity with stable, reliable operation
4. Easy maintenance; low maintenance costs
5. Effective drying when grinding blast furnace slag or blended cements with wet components
6. Consistent cement quality with easy-to-adjust quality parameters
7. Long lifetime
8. Simple, compact layout
9. Proven technology

Vertical roller mill advantages:

1. Simple layout and fewer machines in the mill circuit ensure high run-factor and low maintenance costs
2. Roller and table profile improve operating stability and reliability
3. Special design features for iron removal during slag grinding minimize wear
4. Optimal wear protection on all internal surfaces extends lifetime
5. Flexibility to operate with two or four rollers guarantees long-term availability
6. Segmented roller wear parts made of the hardest possible material without the risk of cracking; very suitable for hard facing
7. Segments are reversible, enabling use of their full width for maximum longevity
