PARTICLE SIZE REDUCTION TECHNIQUES - SlideShare
BALL MILL Principle: The ball mill works on the impact between the rapidly moving ball and the powder material, both enclosed in a hollow cylinder. Thus, in the ball mill, impact or attrition or both are responsible for the size reduction. Fig: Ball mill 13 14. Working: The drug is filled into cylinder 60% of the volume.

Pozzolana Cement (PPC) and Portland Slag Cement (PSC) for different milling systems and examine their effect on physical properties of cements, if any. The milling systems examined for particle shape evolution include Ball Mill, Roll Press followed by Ball Mill (Combi-grinding) and Vertical Roller Mill. 2.0 Materials & Methods:
Particle Size and Shape Analysis of Cement Samples
Particle shape also affects cement properties. Cement that has been ground into particles of a more regular (spherical) shape has a lower surfac e area than cement that is irregularly shaped. Differences in particle surface area will lead to variations of water demand in batches of differently shaped cement. Particle shape analysis will further ...

Vertical mill mainly applied to powder processing of non-flammable and explosive brittle materials with medium, low hardness, Mohs hardness of 6. Ball mill is key grinding equipment afer materials are crushed. Vertical grinding is a "grinding bed" grinding equipment, and ball mill is "single-particle grinding" grinding …
Cement mill - Wikipedia
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.
Ball Mills Or Vertical Roller Mills: Which Is Better For ...
Vertical roller mills Vs ball mills has long been a raging debate in the cement industry. In spite of the fact that vertical roller mills have been around for over ten years now and have gradually become the standard as far as cement manufacturing goes, several cement manufacturers still prefer ball mills for cement production when they want to design new grinding plants or a new integrated ...
