For mining exploitation in mining quarry, vertical roller mill machining is essential milling equipment. Many producers in the purchase price will take into account the vertical mill, quality, after-sales and other factors, in fact, for the production enterprises, the role of vertical roller mill in the actual production is the most important. In the mining industry, the quality and performance of the user more and more attention to the vertical roller mill, so a lot of enterprises in the selection of milling equipment will choose vertical mill. In recent years, the vertical roller mill will be supported by the state, in order to better develop the coal, metal and nonmetal mines to provide technology and equipment to better support, to meet the needs of the development of the national economy of energy. Vertical mill in the mine industry occupies an important position can not be replaced. Currently, the domestic mining industry has been in the mining gradually scale large-scale, continuous production, modern equipment draw trend to vertical roller mill represented intelligent mining research and development, the development of scientific and technological progress in the direction of large-scale mining, mining technical want to hydraulic technology, linkage and automation development. vertical mill is widely used in the mining industry and customer recognition, vertical roller mill with market demand, and constantly improve their products and optimize the product structure, and actively introduce advanced foreign technology development, research and development to produce more high-performance vertical roller mill. Vertical roller mill is suitable for a variety of powder preparation, such as powder processing of raw materials such as ore, gypsum mine. Because of the vertical mill and stable performance, strong adaptability, high performance price ratio, vertical mill introduced from foreign countries in the past 20 years, the processing of raw materials have been widely used in the mining industry. In recent years, through continuous improvement of technology, the vertical roller mill feed size 25mm calcite grinding, has greatly improved the performance and power consumption, vertical roller mill has significantly higher performance than traditional milling equipment.
Vertical roller mill is a kind of high efficiency and low consumption of superfine powder processing equipment, greatly reducing the cost of production. In the process of using it, little vibration, low noise, so that it is favorable to the environmental protection work. Within it, the hot air in the mill can contact directly with the material, therefore, its strong drying capacity, saving resources. By adjusting the temperature of heated air, can meet the different requirements of humidity material. Vertical roller mill equipment is more sophisticated machinery and equipment, so in daily use, it is very important to maintain influence in the life of the machine to a large extent, the impact of normal production. Vertical roller mill is one of the milling equipment indispensable in many modern production are inseparable help vertical mill. When in actual operation, many operators will encounter a variety of failures, if not timely maintenance will lead to normal production has been greatly affected, and even production safety accidents. Vertical roller mill common fault is diverse, more just introduced one of the most common types. In the production process, all the operators have common faults vertical roller mill attach great importance to the timely detection of faults and find effective solutions and timely resolve common faults vertical mill, so as to ensure that the equipment normal operation, to ensure maximum production efficiency of enterprises.
At present, the main use for the raymond mill equipment, roller machine, rod mill, of which Raymond machine and mill use is more common. But these traditional milling equipment the presence of high production costs, low productivity, pollution and other shortcomings. Thus, a low cost of production, production capacity, less polluting superfine vertical roller mill came into being, has been widely used in various industries minerals processing, the effect is obvious. The reliability of vertical roller mill machine, high stability, less maintenance, repair directly, so it directly reduces the cost of repair material expenditure. The normal production conditions, the vertical mill repair material cost is the most direct roll grinding, grinding and so easy to wear parts replacement and repair. But the roller wear to a certain extent, also can be turned to repeated use, to extend the life cycle of roll mill. Cement raw material vertical roller mill is adapted to the medium and small closed loop efficient mining, chemicals, building materials, metallurgy and other industries of high fine milling equipment. Cement raw material vertical roller mill adopt advanced structure of similar foreign products, and on the basis of large vertical roller mill is designed to improve the update, cement raw material vertical mill equipment is higher than the mill efficiency, low power consumption, small footprint, less time investment. Cement raw material vertical roller mill grinding roll under the action of centrifugal force on the tightly rolled grinding ring, so when roller, grinding ring wear to a certain thickness does not affect the yield and the fineness of the finished product. Cement raw material vertical roller mill, grinding ring replacement long period of time, thus excluding the replacement of wearing parts centrifugal mill short cycle ills. The cement raw material vertical mill is winnowing fan airflow - mill shell - Cyclone - within the fan circulating the job, so less dust than the high-speed centrifugal mill, operating plant clean, pollution-free environment.
