This paper presents an application for mill control. In this application a mill is controlled by software running on Programmable Logic Controllers. The paper handle a few topics from cement industry, such are: critical speed, mill speed control. If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back. Therefore, this application

Mill Speed
The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell''s inside surface. This is the rotational speed where balls will not fall away from the mill''s shell. Result #1: This mill would need to spin at RPM to be at 100% critical speed. Result #2: This mill''s

Raw mills usually operate at 72-74% critical speed and cement mills at 74-76%. 3.2 Calculation of the Critical Mill Speed: G: weight of a grinding ball in kg. w: Angular velocity of the mill tube in radial/second. w = 2*3.14*(n/60) Di: inside mill diameter in meter (effective mill diameter). n: Revolution per minute in rpm. 7.

Cement mill Wikipedia. Ball mills are normally operated at around 75% of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm The mill is usually divided into at least two chambers (although this depends upon feed input size mills including a roller press are mostly single-chambered), allowing the use of different sizes of grinding media

In this study, it was found that optimum grinding occurs at 85% of critical speed, compared to the optimum grinding at 70% of critical speed of the ball mill in the cement factory. The variation of a T values with the fraction of mill critical speed ( φ c ) gave high correlation coefficients of 0.98 and 0.96 for clinker and limestone

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.
