8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 20–40 water by weight.

Cement Ball Mill Structure. When Ball Mill is working, raw material enters the mill cylinder through the hollow shaft of the feed. The inside of the cylinder is filled with grinding media of various diameters (steel balls, steel segments, etc.) when the cylinder rotates around the horizontal axis at a certain speed, Under the action of centrifugal force and friction force, the medium and the.

Cements Ground In The Vertical Roller Mill Fulfil The

Ball mills are factory made and transported to the plant site of the buyer while VRM is built on the site of the cement plant. This helps to reduce cost and complicated logistics issues. The equipment cost is, however, higher for a VRM than a ball mill. So these are the pros and cons of the two technologies and a cement manufacturing company.

Modelling of fully airswept ball.

The Operating Principle Of The Ball Mill

Aug 30, 2013 As the retention time in ball mills is 20 to 30 times greater than in vertical roller mills, the cement is exposed to the hot- gas atmosphere for much longer. In addition, ball mills use much energy than vertical roller mills in order to grind the same amount of cement, with this additional energy heating the material even further.

The Operating Principle Of The Ball Mill

Cement grinding Vertical roller mills versus ball mills. 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 effective than ball mills.

In 1904, Krupp produced a self-contained cement mill using a ball mill and their version of the Askham separator in closed circuit, but I think this was never used in Britain. However, from the mid 1890s, ball mills were used in combination with tube mills (see below) and this setup became the normal cement milling installation until 1920.
