Especially, when grinding slag cement, its performance is outstanding. Generally speaking. Production could be 10 20 higher, and power consumption 10 lower. Besides, product temperature could reduce 20 40 C and.Seen, the vertical mill consistently presented lower net specific energy consumption than the ball mills which operate on the same circuit. The averages were 11.3, 11.7 and 6.5 kWh t respectively for ball mill 01, ball mill 02 and vertical mill. Figure 5 – Net specific energy consumption of regrinding circuit.
Read MoreKeywords Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc.In order to reduce the power consumption of the ball mill machine, the feed size can be reduced. Therefore, the particle size of the crushing product is required to be small, that is, “ crushing and less grinding”. 3. Control the filling rate of steel ball.
Read MoreJul 04, 2018 (The power consumption of the system itself is 75 to 80 of the ball mill) (9) The metal wear of the unit product is low. The wear is generally only 5 to 15 g t, and even only 3 to 5 g t. Therefore, the wearing parts have long service life the metal powder resulted from metal wear is small, so vertical roller mills can grind the white cement.They have lower specific energy consumption than ball mills and the separator, as in raw mills, is integral with the mill body. In the Loesche mill, Fig. 2.23 , 16 two pairs of rollers are used. In each pair the first, smaller diameter, roller stabilises the bed prior.
