VRM vs Ball Mill for Cement Grinding. Good Days Gentlemen, Anybody in this forum who have had some practicalextensive experience on Vertical Roller Mill being used for cement grinding We are planning to put up a new cement grinding plant using Vertical Roller Mill300350 TPH and before implementing the project, we would like to
Get Pricefinish grinding of Portland cement, slag and blended cements. The mill consistently uses five to ten percent less power than other cement vertical roller mills, and in comparison with traditional ball mill operations, the energy requirements for the OK cement mill is 3045 percent lower for cement grinding and 4050 percent lower for slag.
LEADING TECHNOLOGY IN BALL MILL CONTROL. With MillMaster KIMA Process Control offers the most robust, open and easy to handle Advanced Control System in the Cement Industry. Since 1996 this AutoPilot system was installed in hundreds of cement plants to operate mills fully autonomously.
Optimization of Cement Grinding Operation in Ball Mills. Contact Us . Several energy efficient options for cement grinding are available today such as vertical roller mills, roller presses typically in combination with a ball mill, and clinker pregrinders with ball mills.
A 10 MW cement mill, output 270 tonnes per hour. A cement mill or finish mill in North American usage is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
A typical comparison of three competing technologies is given in Table 1, demonstrating that an efficient ball millthirdgeneration separator, CKPball millthirdgeneration separator and vertical mill on a typical 4000Blaine limestone cement show little overall difference in energy consumption.
Common types of grinding mills include Ball Mills and Rod Mills. This includes all rotating mills with heavy grinding media loads. This article focuses on ball and rod mills excluding SAG and AG mills. Although their concepts are very similar, they are not discussed here. Photographs of a glass ended laboratory ball mill show action of ball mass within the mill. The action of other grinding

cement ground in OK mills similar to those for cement ground in ball mills BM, as shown in Figure 6. Figure 6 B It should be noted, however, that operation to achieve a wide particle size distribution low nvalue has a cost. The measures taken to achieve a low inclination of the PSD
Abstract As the Vertical Roller Mill VRM becomes more widely accepted for new cement grinding systems differences in installed costs between a VRM and a ball mill system are more frequently discussed. Past comparisons of total installation costs for a ball mill with high efficiency separator versus a VRM have indicated the higher equipment costs associated with the roller mill made it a
Vertical roller mill adopts threedimensional structure,which needs less space,ball mill is just the vertical roller mill is cheaper than ball mill,if you don39t need high productivity,roller mill is a better choice. I think this note,which called what is the difference between vertical roller mill and ball mill can help you.
The effect of Ball Mill RPM speed going from subcritical to supercritical helps understand the Ball Mill Working Principles of ballonball VS ballonshell grinding. The Motion of the Ball Charge
When the mill is rotated without feed or with very fine feed, the rods are in parallel alignment and in contact with one another for their full length. New feed entering at one end of the mill causes the rod charge to spread at that end. This produces a series of wedge shaped slots tapering toward the discharge end. The tumbling and rolling rods expend most of their crushing force on the
A ball mill crushes solids into a fine powder within a rotating drum, using balls as the grinding medium. Applications. Ball mills are found in settings as diverse as laboratories and mines, among others.
The mill used for this comparison is a 4.4meter diameter by 13.6 meter long ball mill with a 5000 HP drive motor. It is designed for approximately 90 per hour. This type twocompartment mill is a state oftheart shell supported cement finish mill.
The OKTM mill can skilfully grind raw or cement feed material and offers parts commonality, simplifying spare parts inventory and facilitating easy switching of parts between vertical roller mills. Our ATOX coal mill has large rollers with great grinding capability of all types of coal, tolerating moisture levels up to 20 percent.
Developed in 1966, our twostage planetary gear unit guarantees optimum power transmission and speed reduction for your ball mill. The standard for central driven ball mills in the cement industry today, our MAAG GEAR CPU Gear Unit drives hundreds of raw and clinker ball mills all around the globe.
