Vertical roller mills Vs ball mills has long been a raging debate in the cement industry. In spite of the fact that vertical roller mills have been around for over ten years now and have gradually become the standard as far as cement manufacturing goesseveral cement manufacturers still prefer ball mills for cement production when they want to design new grinding plants or a new integrated
A raw mill is the equipment used to grind raw materials into rawmix during the manufacture of cement. Rawmix is then fed to a cement kilnwhich transforms it into clinkerwhich is then ground to make cement in the cement mill.The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cementand has a large effect upon the

The vertical roller mill (VRM) is a type of grinding machine for raw material processing and cement grinding in the cement manufacturing process.In recent yearsthe VRM cement mill has been equipped in more and more cement plants around the world because of its features like high energy efficiencylow pollutant generationsmall floor areaetc.
The specific energy consumption of a ball mill is greater than a vertical roller mill (VRM) that performs the same operations by a factor of between 1.5 and 2depending on the degree of optimization of the ball mill. Finish Grinding System. The common cement grinding systems are summarized in Figure 1 and can be divided up into three main groups:
These have been used for many years for the less exacting raw-milling processbut recently roller millsin combination with high-efficiency separatorshave been used for cement grinding. The grinding action employs much greater stress on the material than in a ball milland is therefore more efficient.
Vertical cement mill has high grinding efficiency and low power consumption (20% 30% less than ball mill). The granularity of the feeding material is larger(VRM cement mill is 80mm-120mmcement ball mill is less than or equal to 30mm). Cement vertical mill occupies less space and saves 30% of construction cost.
finish grinding. High energy consumptionincreasing demand and the emission of CO 2 necessitate the efficient grinding technologies. Among these technologiesvertical roller mills have an important position in cement industry. Vertical roller mills are widely used for especially grinding of coalcement raw materialsclinker and

Aug 132015 McInnis has installed a vertical raw mill for raw meal preparation and two identical vertical finish mills (8,400 tpd) with high-efficiency separators between the 120,000 mt of clinker storage and the 120,000 mt of cement storage silos. This enables the plant to remain balanced during times of peak demand.
grinding of raw materials. The grinding efficiency of the vertical roller mill combined with an ability to drygrind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system. Howeverdespite these benefitsapplications of the vertical roller mill for cement grinding are less prevalent.
