Non-metallic mineral powder processing industry, LM Vertical Grinding Mill industrial scale and the degree of product refinement has become a measure of a country’s non-metallic mineral industry, an important indicator of the level of development, and energy efficient large-scale equipment and advanced production and processing technology is the realization of non-metallic mineral Powder processing industry scale and the key to the development of industrial refinement. As one of the main equipments of non-metallic mineral powder dry-processing technology, the technology of vertical milling machine highlights the advantages of high efficiency, energy saving and environmental protection in the application of non-metallic mineral industry scale and product refinement. And promote the non-metallic mineral industry scale, fine product development.
There are two types of Dolomite Powder Milling Machinery for grinding ground slag in China, one is hydraulic vertical grinding mill, such as red star machine, based on the introduction of digestion, after long-term production practice, optimize the design of the equipment structure Grinding equipment of all kinds of mineral powder, on behalf of Model LM vertical mill, it can grind 1250 mesh the following kinds of slag; the other is the spring pressure of the vertical mill, such as Raymond Mill. Compared to the two, the vertical pressure of hydraulic high degree of automation, a single large output, high energy efficiency, reliable operation, product size should be adjusted, stable performance. Vertical grinding mill in grinding cement raw materials operations, the general use of kiln exhaust gas on the material drying, therefore, the task of system design, in addition to determine the basic structure of the system form, but also by thermal calculation to determine the typical operation Parameters, supporting equipment specifications and models, and develop the necessary process control means. According to material balance requirements to determine the amount of material entering and leaving the mill, evaporation and out of the mill the amount of wind, according to heat balance to determine the entropy of the wind into the wind, according to kiln and grinding air volume, the comparison of the results of the heat to develop the appropriate process measures. Material performance is an important factor affecting mill output, hardness of the material is more difficult to grind, the lower the mill output. Therefore, when the vertical mill grinding hard material, to achieve the same material with the fine grinding of the same fineness, is bound to increase the number of grinding the material, the material in the mill to stay longer, increase the cycle load within the mill , The system output must be reduced.
Effect of System Leakage on Mill Output
As the entire Stone Crusher Machine Manufacturer In India system is in a high negative pressure state, if the seal is poor, it will leak into a large number of cold air, thereby reducing the system wind speed and a corresponding increase in the system useless work to increase power consumption. Vertical mill feeding three-way valve and slag sluice lock wind device, electric dust zipper, the system duct flange junctions and other parts of the air leakage easily, it will cause the mill inlet and outlet pressure drop smaller, wind speed is not enough , The material can not be taken away in time, affecting mill output. Also reduce the wind speed will result in the accumulation of pipe material, pipe accumulation of materials, the ventilation area will be reduced, the air flow will also affect the mill production. So timely check the air leakage problem is also necessary.
