A raw mill is an equipment to grind cement raw materials: limestone, clay, silica stone, iron oxide and gypsum. These materials need to be mixed in appropriate proportion. Blast furnace slag from iron steel plants, ash from waste incineration plants are also used as cement raw material. In a raw mill these raw materials are ground with roller ...

Abstract. Cement sector in india is enjoyign success and capacity enhancement due to the rapidly growing demand in various sectors but at the same time a threat is approaching to cement industry that its input cost is increasing day by day like power cost, fuel cost, raw material cost. Also cement is a highly energy consuming industry.

Grinding systems in cement production make up approximately 85 to 90 percent of total plant electrical energy consumption. As vertical roller mills are 30 to 50 percent more efficient than other grinding solutions, they give cement plant owners a great opportunity to. maximise productivity and minimise operating costs.

The cement mill (or finish mill) presents a convincing case for automation as the optimization process employed by many cement manufacturers is mainly manual. Particle fineness of the cement is measured by way of Blaine measurements, routinely carried out separately offline. In a conventional setup, peak performance was ensured by manually ...

Raw material preparation and cement making are the main electricityconsuming processes, whereas the clinker kiln uses nearly all of the fuel in a typical cement plant. Clinker production is the most energyintensive production step, responsible for approximately 70 to 80% of the total energy consumed.

Summary of production process. Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of ...

14 Cement Mill and Bag House . Clinker, along with additives, is ground in a cement mill. The output of a cement mill is the final product viz. Cement. In a cement mill, there is a cylindrical shell lying horizontal which contains metallic balls and as it rotates, the crushing action of the balls helps in grinding the clinker to a fine powder.
