Advanced Raymond mill or paired with classifier, can also make 600-1250 mesh calcium carbonate powder. However, as mentioned above, the low proportion of fine powder means low production capacity and high energy consumption. So it is not advisable and economical to make calcium carbonate powder above 600 mesh. Roller Mill
Bhasker has investigated flow paths in the classifier of a roller mill, and trajectories of 25 μm coal particles were obtained by applying computational fluid dynamics (CFD) . And for a simplified industrial pulverizer, Vuthaluru et al. have conducted numerical simulation to compare the motion of air and 100 μm and 500 μm coal particles.

For radial cylindrical roller bearing, db-6 wavelet is initially used for decomposition, and then ANN and SVM methods are compared by selecting the 173 features out of available 369features. After simulating 70 models, ANN gives accuracy 84–93% while the least square SVM method proves better with 75– accuracy.
A mill classifier shown in FIGS. 1 and 2 is a roller mill classifier 2, which can be mounted on a roller mill. The roller mill is intimated by grinding rolls 37 and a grinding path 39 . In a classifier housing 23 with an upper part 25, the roller mill classifier 2 has a dynamic classifier part 6 and a static guide vane ring 4 for an upwardly ...
rotating classifier. After the last feed input the central to the mill table, due to mill and roller's relative movement, materials get into the grinding layer between the roller and the mill. In suspension between classifier and table, material drying transpires will takes place. The unstable grinding bed causes the VRM to vibrate.
The low grinding efficiency of the ball mill, low processing capacity, high production energy consumption, and unstable product fineness are the problems that most concentrators will encounter. How to effectively improve the grinding efficiency of the ball mill is an important issue.

classifier itself – such as separation efficiency or pressure loss – the materials to be classified also play a role. The lamellar classifier developed in 1928 was followed by pressure-shock-resistant classifiers for coal mills, rotary classifiers for very moist materials and louvre classifiers for example for creating fine and coarse products.
