This paper deals in first place with roller mills for raw material processing. For grinding coal, slag, cement, etc., adaptations to mills and systems have to be made. 2. FUNCTIONS OF THE ROLLER MILL The vertical roller mill fulfills 4 main functions in one compact piece of equipment: ¢ Grinding « Drying ¢ Separation ¢ TransportRoller mills are now operated with throughput capacities of more than 500 tons per hour of cement raw mix (Loesche-mill, Polysius double roller mill, Pfeif fer-MPS-mill, SKET/ZAB-roller mill).

Sepriadi Sepriadi. Grinding/crushing is a process of reducing the size in a crushing plant to get the desired size. The coal ball mill technique is where the ball collides with the feed on the tube wall, thus cracks will form in the feed which will result in a smaller size. Limitation of the problem in this study is the effect of speed on timeThe two-time breakages are far closer to the actual product size distribution. This study investigated a mathematical model for an industrial-scale vertical roller mill (VRM) at the Ilam Cement Plant in Iran. The model was calibrated using the initial survey's data, and the breakage rates of clinker were then back-calculated.A cement Vertical Roller Mill modeling based on the

Vertical roller mills: The new leader in grinding technology
The two most common compressive comminution technologies are the high pressure grinding roller (HPGR) and the vertical-roller-mill (VRM). For now, the HPGR has already presented in a noteworthy number of mining projects whereas VRM technology, a new entrant, is still not fully accepted. This is considered a resistance to change The raw vertical roller mill has four rollers, 3000 KW main drive, 4.8 m table diameter, 2.16 m roller diameter with 330 t/h capacity (made by LOESCHE Company from Germany).Modeling of energy consumption factors for an industrial

The application of vertical roller mills (VRMs) for ore grinding is a part of the strategies against rising energy consumption (Reichert et al., 2015). The VRM technology was introduced in the mid-'90s for grinding clinker and slag by LOESCHE (Schaefer, 2001).

Vertical Roller Mill Working Principle. When the vertical mill works, the motor drives the grinding disc to rotate, and the grinding roller rotates around the grinding roller shaft driven by the disc. The material entering from the feeding port falls in the center of the grinding disc and moves towards its edge under the action of centrifugal
