Vertical Roller Mill For Cement

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.

Cost Savings

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 plant's overall electrical power consumption. VRM technological innovation makes important power reductions feasible by a lot more effective grinding.


Vertical roller mills develop a particle dimension distribution with a sharper cut in comparison to cement milled in a regular ball mill. Which is, the particle dimension distribution is within a narrower band. This sharper reduce means probably significantly less variability in product or service consistency and, therefore, additional predictable outcomes in solution performance.

Process Simplification

By changing numerous vertical roller mill working parameters, major changes while in the particle size distribution, retention time, and fineness from the finished cement can be attained. This could assist with plant operations as production is switched among various cement varieties.

In light of these problems, vertical roller mills are becoming a well-liked decision for each current ball mill conversion and new mill development. From 2000-2002, 56% in the mill orders (comprising the two raw mills and finish mills) came from vertical mills 'C in comparison with 32% for ball mills. Evidently vertical roller mills are an increasingly appealing alternative for improving production, decreasing energy fees, and sustaining product quality.
