CEMENT ADDITIVES FOR VERTICAL MILLS 04 2. VERTICAL MILLS INTRODUCTION Thanks to the necessity to improve grinding efficiency and reduce operation costs, vertical mills have made their way into the cement industry. At first these new systems were employed for the grinding of solid combustibles and kilnfeeding raw meal. In the past decade,
· Raw mix is stored in a prehomogenization pile after grinding raw mix to fine powder. Cement Manufacturing Process Phase III: Preheating Raw Material. After final grinding, the material is ready to face the preheating chamber. Preheater chamber consists of series of vertical cyclone from where the raw material passes before facing the kiln.
Vertical roller mills (VRM) have found appliions mostly in cement grinding operations where they were used in raw meal and finish grinding stages and in power plants for coal grinding. The mill combines crushing, grinding, classifiion and if necessary drying operations in one unit and enables to decrease number of equipment in grinding circuits.
· Operating experience with the new PolysiusQuadropol. 2. raw mill. The fundamental market demands on a cement raw material grinding plant are high throughput rates and drive power combined with small construction size and high availability. These are precisely the performance characteristics of the new roller mill generation from TKIS.
· Raw mix, high grade limestone, sand and iron ore are transported from their bins to raw mills for drying and further fine grinding. The raw mill is either a Ball mill with two chambers or Vertical roller mill with inbuilt classifier. The hot gases from the pre heater enter the mill and are used for drying material in the mills.
The most used coal mills in cement plants are airswept ball mill and vertical roller mill. At present, most cement plants use coal as the main fuel in the clinker production process. The standard coal consumed by the new dry process for producing 1 ton of cement clinker is usually between 100 kg and 130 kg, and the fuel cost accounts for about 15% of the cement production cost.
cement. In early 1960, the bowl and roller mills were modified by Babcock. The air separators of the mills have to meet high requirements with regard to process technology and operational safety. To date, the dynamic air separators (type SLS) were driven via a pinion gear. These required four point bearings with a toothed outer ring.

Cement plants are designed based on the raw materials and fuel samples tested by the equipment supplier. ... Raw materials are a major variable in this evaluation. Raw mill ... In the case of vertical roller mills, inspection of the mill internals and adjustments in the operation will bring about an improvement in the energy consumption and for ...
The VRM for cement grinding offers a significant advantage in power savings. Typically, the VRM uses 50% less power than a ball mill when grinding the same clinker to 3900 Blaine. VRMs are also much more adept at handling hot feed compared to ball simple and compact vertical mill layout is cost competitive to build and offers many options for layout, even in existing plants.
Cement vertical roller mill vrm is mainly used to grind cement clinker into fine powder during cement production this vertical cement mill is widely used in the grinding of cement raw meal cement clinker slag raw coal and other raw the vertical mill by pneumatic conveying materials, a larger air flow, which can use the waste heat from the gas, while drying the grinding operation.
· Pfeiffer SE provide solutions for the cement industry that are ideally suited for meeting the requirements for ever increasing production outputs and progressively greater availabilities. Operating experience gained in more than 25 000 hours is meanwhile available for both the MVR vertical roller mill and the MultiDrive ®.
Vertical roller mill is mainly used for grinding raw meal, clinker, GGBFS(Ground Granulated Blast Furnace Slag), iron ore, limestone, coal powder, coke powder, coal gangue, fly ash, volcanic ash, gypsum, calcite, pyrophyllite, quartz, clay, sandstone, bauxite and other processing industry related to metal and nonmetal mine
