There is a large gap between the tip speed and power intensity of the low-speed vertical mills and the high-speed horizontal mills. The VXP mill bridges the gap between high-speed and low-speed mills. The VXPmills are designed for fine and ultra fine grinding applications. In practice, the mill performs best when the feed has a normal distribution.

Re: Cement mill Residue. Hi Jatinder, You could increase the speed of your separator rotor, i.e. increase recirculation load. But you may then experience an excessively high blaine value. The best way to make a balance on mesh passing and blaine is to play around with feed tonnage and separator rotor speed. Branco. Reply

The duration of the wet-milling process was 10 min and 20 min at an autorotation speed of 400 rpm to obtain CSW1 and CSW2 respectively With the increase of wet-milling duration, W5-20 and W10-20 are lower than that of cement. With the increase of wet-milled CSW dosage, the most probable pore size decreases.

First, The Adjustment Of Motor Speed. This method is mainly to adjust the spindle speed of the vertical roller mill by a large margin, so that the positive pressure of the grinding roller against the grinding ring can be changed, and the grinding effect can be changed. In addition, the adjustment of the fineness will change the output.

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. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
