Vertical Roller Mill For Cement
With the continual escalating demand for portland cement and continual strain for lowered vitality usage, producers are exploring a broad selection of cost-saving manufacturing solutions. One alternative is vertical roller mill technological innovation for finish grinding.
For many decades the cement market has efficiently utilized Vertical Roller Mills (VRM) for grinding of raw materials and sound fuels. Most not long ago, this technologies continues to be employed for that comminution of Portland cement, blended cements and slag cements.
The VRM provides quite a few advantages compared to the ball mill in regards to working charges and flexibility. Nevertheless, the good quality of the cement made is particularly critical in cement grinding and there’s tiny expertise with cement created from a VRM in the US market place.
The grinding process in ball mills and vertical roller mills vary fundamentally. Within a ball mill the comminution will take area by impact and attrition. The comminution during the vertical roller mill will take spot by exposing a bed of material to a pressure sufficiently high to induce fracture from the person particles while in the bed, whilst the majority of the particles during the bed are considerably smaller sized than the thickness of your bed.
It really is thus essential that a stable and steady grinding bed is formed amongst the rollers along with the table from the vertical roller mill, in a position to sustain this kind of a stress with out the materials staying squeezed away from your strain zone.

The single biggest energy consumption point inside the manufacture of portland cement is within the finish milling process. A reduction in power consumption right here can make a dramatic impact within the plants overall electrical power consumption. VRM technological innovation makes important power reductions feasible by a lot more effective grinding.
