More Details:
grinding is an important process for the production of cement, it not only determines the unit power consumption of cement production, but also on the performance of cement is very important. For a long time, the cement grinding is in the cement mill, cement mill has the advantages of simple structure, reliable operation, convenient maintenance and management; high adaptability to raw materials, continuous production, high production capacity; big crushing ratio, easy to adjust the fineness etc.. However, the effective utilization rate of energy is only 2%-5%, and most of the remaining energy is converted into heat energy, and the economic benefits are not the best. In recent years, the traditional cement mill has been upgraded and upgraded with a new type of powder mill closed circuit system. Therefore, cement grinding technology has been developed rapidly. Especially the emergence of vertical mill, greatly reduce the energy consumption of slag cement grinding, and improve the grinding efficiency. The machine vertical milling machine integrates fine crushing, drying, grinding, powder selection and transportation. It is the best choice for slag cement processing. So, what are the advantages of a mill in comparison to a ball mill? We might as well speak with data. 1 銆?high grinding efficiency. Vertical mill adopts the principle of material bed grinding, and grinding material is 30% lower than ball milling system. (ball milling consumes sound energy and heat energy) 2. The process flow is simple and capital construction investment is saved. Vertical milling machine with separator, using hot flue gas conveying material, need not separator and hoist, which directly into the powder collecting device collects grinding dust containing gas, so the process of milling machine system is simple, low failure rate, high operation rate, compact layout, the construction area of the building space for the 70% ball milling, milling 50-60%. 3 銆?drying capacity. Vertical milling machine with hot gas conveying material, in the large water grinding material (such as coal, slag) can control the inlet temperature, make the products reach the final moisture, mill drying moisture 12-15% materials; even drying mill, only 3-4% of the material for the water drying. 4, metal wear is small. As the vertical mill runs without direct metal contact, the wear is small, and the limestone unit wear is generally 4-6 grams / ton, and the ball mill reaches 500 grams / ton. When grinding white minerals, the whiteness of the mineral is much smaller than that of the ball mill. 5, low noise, dust less. Vertical mill in work, grinding sound soft, generally at about 80 decibels. The grinding roller is not directly contacted with the grinding mill, and the noise is about 20-25 dB lower than that of the ball mill. The mill adopts integral sealing, the system operates under negative pressure, little dust and clean environment. 6, high degree of homogenization of products. The qualified products in the vertical mill can be separated in time to avoid over grinding, and the product size is uniform. It is convenient for the vertical pulverizer to adjust the speed, wind speed and roll pressure of the separator, so that the fineness of the product can be adjusted conveniently.
