Vertical Roller Mill For Cement And Coal Grinding

Vertical roller mill is the large grinding mill that is mainly used in coal grinding plant and cement grinding plant.
Vertical roller mill is the newest grinding machine of vertical mill professional manufacturer-Binq, which is designed specially to solve the problems of low capacity and high consumption of traditional industry mills. With a decade of years research of mills, our vertical mill is designed and manufactured based on advanced design idea, and integrates the advanced international technology and years of mill-producing experience. Vertical roller mill adopts reliable structure and reasonable process flow; it is ideal equipment that integrated with drying, milling, classifier, and elevator. Especially, this 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.
Vertical roller mill are mainly applied to proceed the powder crushing manufacturing of the materials such as calcite, limestone, light dry stone coal, barite, fluorite, glaze, slag, wollastonite, kaolin, vermiculite, mica, feldspar, brucite, spores, potassium salt slag, garnet , quartz,etc.And the Vertical roller mill can also be used to the non-metal mining areas with the Mohs hardness of less than 7degree ,such as mining metallurgy, chemical industry, electronics, medicine, food, daily chemical, agricultural, building, and so on.
Benefits of cement vertical roller mill:
1. Cost Savings

The single largest energy consumption point in the manufacture of portland cement is in the finish milling process. A reduction in power consumption here makes a dramatic impact on the plants overall power consumption. VRM technology makes significant power reductions possible by more efficient grinding.

2. Quality

Vertical roller mills create a particle size distribution with a sharper cut in comparison to cement milled in a traditional ball mill. That is, the particle size distribution is in a narrower band. This sharper cut means potentially less variability in product consistency and, hence, more predictable results in product performance.

3. Process Simplification

By changing various vertical roller mill operating parameters, significant adjustments in the particle size distribution, retention time, and fineness of the finished cement can be achieved. This can help with plant operations as production is switched between different cement types.

In light of these issues, vertical roller mills are becoming a popular choice for both existing ball mill conversion and new mill construction. From 2000-2002, 56% of the mill orders (comprising both raw mills and finish mills) came from vertical mills compared to 32% for ball mills. Clearly vertical roller mills are an increasingly attractive option for improving production, lowering energy costs, and maintaining product quality.
