VERTICAL ROLLER MILL


 

MAIN FEATURES 

 

SIMA vertical roller mills use 30-50% less energy than ball mill systems. Its good for profits, good for the environment. 

Space-saving design reduces civil construc- tion costs. 

Simple layout and operation with fewer machines in the circuit ensure high run-factor. 

Excellent drying makes 

the mill well suited for grinding blast furnace slag or blended cements from one or more wet components.

Low vibration made possible by specially designed roller and table profiles ensures operating reliability.

Curved table increases retention time and grinding bed thickness for smooth operation.

Easy to adjust Blaine and particle size dis- tribution for required cement quality.

During slag grinding, wear is minimized via a special by-pass that removes iron particles from the grinding table.

All exposed surfaces

are wear-protected.


VERTICAL ROLLER MILL

the SIMA VERTICAL ROLLER MILL series is the premier roller mill for finish grinding of Portland cement, slag and blended cements. With a 30-45% reduction in the energy requirements forcement grinding and 40-50% for slag as compared with traditional ball mill operations,

The SIMA mill can contribute significantly to your profitability and competitiveness.

 

The design combines the drying, grinding and separation processes into just one unit, thus simplifying the plant layout. A low noise level makes outdoor installation feasible,


Substantially reducing
civil construction costs and improving the working environment.

 

Because of its highly effective drying performance, the SIMA mill is a natural choice for grinding blended cements with one or more wet components.

 

Design advantages

Depending on its size, the SIMA mill has three or four rollers. They are hydro-pneumatically pressed against the material bed on the rotating grinding table.

A patented grooved roller profile creates a high and concentrated grinding pressure on the outer path, allowing air to escape in the middle. The inner path serves to even out and consolidate the material before it continues to the next roller.

The segmented roller wear parts can be made of even the hardest material without risk of cracking and are very well suited for hard facing. Moreover, the segments are reversible, so their full width can be utilized. These features ensure maximum longevity.

 

Operating advantages

The rollers are in a lifted position when the mill is started, ensuring trouble-free startup. This eliminates the need for an auxiliary drive. A control system supervises the machinery and facilitates operation.
