Vertical roller mill

Vertical roller mill combines the drying, grinding and separation processes into just one unit, which simplifies the plant layout. And because it operates at a low noise level, outdoor installation is feasible – substantially reducing civil construction costs and improving the working environment.

Lm vertical roller mill can fully meets the requirement of clients in the high production of powder and its main technical and economy indicator reaches the international level, and has reliable structure and reasonable process flow, high grinding capacity and low energy consumption.

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 minimise 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 hardfacing
7. Segments are reversible, enabling use of their full width for maximum longevity

Vertical roller mill in cement plant :

Usually, cement plant used ball mill to grind clinker and gypsum into cement, now vertical roller mill presents a compact and efficient grinding method. Clinker and gypsum is ground on a rotating table that passes under large rollers. Material is forced off the table by centrifugal force, where it is then swept up into an airstream to a classifier immediately above. Just as with a ball mill, material that is too coarse is returned to the table for additional grinding while material that is fine enough is collected as product. The compact design of a vertical roller mill allows it to dry, grind, and classify, all within one piece of equipment and all in a relatively compact space. Vertical roller mill technology allows: (1) power consumption savings; (2) consistent product quality and (3) process simplification.
