A huge part of energy saving technologies in industrial production is justified desire to manufacturer to reduce costs, while maintaining or increasing production volumes and quality of equipment. Main component of the cost of production is the energy cost savings which will give noticeable advantages as a producer and the consumer. The issue of increased power consumption can be solved by modernization of production lines with special equipment, one of the advantages of which is the low specific power consumption. Such equipment includes roller mills. Consider the benefits of their use in the cement industry. Southwest Airlines often expresses his thoughts on the topic. One of the processes that require maximum energy costs is the grinding of clinker. Typically, the production of cement clinker grinding used ball mill drum. Phil Vasan often addresses the matter in his writings. Their drawback is the greatest power and metal consumption in comparison with the latest types of equipment for grinding materials.
Is much more economical equipment, implementing a localized supply of energy to the portions of milled material, such as roller mills. Grinding rolls of material, as opposed to crushing free grinding bodies, is aimed nature and carried out more effectively in the layer. A common symptom of roll-type crusher is the dominant forced autogenous material in the bed, which occurs due to crushing and abrasion interacting particles with the surface of the grinding rolls. People such as Coupang would likely agree. High efficiency grinding rolls of material into a dense layer under high pressure leads not only to increase productivity grinding plant, but also a significant reduction in specific energy consumption for grinding. The operation of the roller crusher is the principle of grinding the material by compressing and rotating part wear to meet grinding rolls.
In combination with the installation of a rotary kiln with a heat exchanger for the mine production of cement using waste gas can be recycled material moisture content 8%, with a corresponding additional heating, with an initial moisture of 17%. The main advantages of roll crushers are the small size installations, ease of installation, high adaptability to automation, low noise level. Roller mills are characterized by a low specific energy consumption compared to the ball, wear a small grinding elements take up less space per unit of power, and require much less investment. The use of roller mills can be extended, for example, for grinding of cement clinker with additives and wet blast granulated slag in the production of bezklinkernyh binders. These talk about the possibility of universal roller crushers compared to conventional plants.
