Cement mill Wikipedia

A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage [1]) 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.

High Energy Ball Mills Instead of Planetary Ball Mills

To offer a solution, RETSCH developed the High Energy Ball Mill Emax which is able to grind many different substances to particle sizes < 100 µm and usually in a much shorter time than required by other ball mills. Ideally, the grinding breaks can be skipped altogether, which results in enormous time savings.

7 Major Differences between Ball Mill and Rod Mill

3. Different grinding medium. The Rod mill usually uses the steel rod with a diameter of 50100mm as the grinding medium, while the ball mill usually uses the steel ball as the grinding medium. The steel balls of ball mill are in point contact, while the steel rods of Rod mill are in linear contact, so their working ways are obviously different.
