Vertical raw mill in cement plant Rwanda Gravel HighEfficiency Roller Mills Industrial Efficiency . ball mills are used in cement industry for raw material, installation of a vertical mill for raw material.The vertical roller mill is well known in the cement and power plant industries as the preferred mill for grinding of raw materials. It is increasingly used as a solution for efficient grinding. Within the cement industry, vertical roller mills are becoming important as cement producers look to increase their use of clinker substitute.
It was decided that at Hub, for all grinding processes Loesche vertical roller mills will be installed. Thus, the contract comprises one raw material mill for 654 t h raw meal with a COPE drive, one cement mill for 445 t h OPC with a COPE drive as well as a coal mill for 66 t h.The increasing number of vertical roller mills in cement grinding and the widespread use in raw material grinding leads to another advantage of this mill sys-tem. Because of weight-reduction during the pyro-process and the different grindabilty of raw materials and clinker, it is possible to erect production lines with only one large raw mill.
The OK™ Mill was originally designed for cement grinding. In 2017 we released the OK™ vertical roller mill for raw materials grinding. The OK™ Mill’s modular design comes with unique flexibility, showcasing parts commonality, where spare parts can be shared between vertical roller mills regardless of size and application.The largest vertical roller mill in the world is also equipped with state-of-the-art grinding rollers. The grinding rollers have internal and external grinding zones. The rollers ground the raw materials under extremely high pressure converting the raw materials to ﬁnely-grinded particles evenly shaped and distributed to the mixture.
Raw Meal Process Control (Dry process - Vertical Mill). The main difficulty with existing vertical roller mills are vibration trips. Operation at high throughput makes manual vibration control difficult. When the raw mill trips, it cannot be started up for one hour, until the motor windings cool.2. After grinding system has started, please turn on the rod valve in the bottom of raw coal storage, and start sealing measuring belt to coal mill, then raw coal will be dryed and ground in the vertical coal mill. 3.
