The finished product cement from this system has all been further ground in the ball mill, so it has wide particle size distribution and stable performance. However, due to the fact that the materials rolled by the roller press are not sorted, a large amount of fine powder is returned to the roller press. If the return proportion is more than ...

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.

The press can be installed in combination with a tube mill (new installation or expansion of an existing mill) or as a finish grinding system. GENERAL DESIGN AND WORKING PRINCIPLE General Design (Figure 1) 'The design of the roller press is dependent on the supplier, however, the basic construction is very similar for all makes.
