In the last decade vertical mills have taken an increasing share of the cement milling market, not least because the specific power consumption of vertical mills is about 30 less than that of ball mills and for finely ground cement less still. The vertical mill has a proven track record in grinding blastfurnace slag, where it has the additional advantage of being a much more effective drier
When the required particle size of the finished product is less than 0.5mm, it ismended to use a ball mill. The steel rod and the material are in line or surface contact, and most of the coarse particles are first crushed and then ground. Therefore, the finished product is uniform in quality, excellent in particle size, and high in
The L/D ratios of ball mills range from slightly less than 1:1 to something greater than 2:1. The tubepartment ballmonly used in the cement industry have L/D ratios 2.75:1 or more. The fraction of critical speed that the mill turns depends on the application, and most mills operate at around 75 of critical speed. Increased speed generally means increased power, but as the

If the radial depth of cut is less than the tool radius, the tool is only partially engaged and is making a peripheral cut. If the radial depth of cut is equal to the tool diameter, the cutting tool is fully engaged and is making a slot cut. A large radial depth of cut will require a low feed rate, or else it will result in a high load on the tool and reduce the tool life. Therefore, a feature

24/07/2009· I struggle with the speeds and feed rates for small ball end mills 0.03125, 0.040, 0.0625 when cutting our typical tool steels such as P 20, A2, and H13. We are limited to a maximum spindle speed of 15,000 rpm. Do you concentrate on the sfm for finish end mills of the same diameter, or do you consider that the center of the ball is going to push harder for a given feed per tooth? Then
Each end mill has flutes on its cutting head that carry the removed material away from the workpiece to prevent damage to the end mill or workpiece. Ball end mills create a round bottomed groove in a workpiece. Square end mills cut a flat bottomed groove with 90° inside corners. Corner chamfer and corner radius end mills make a flat bottomed groove with chamfered or rounded inside corners
