In the cement production process, grinding raw material is an important part of the cement production line, the performances of raw material grinding powder equipment is directly related to the normal operation of the cement production line and economic benefits. With the improvements of modern powder making technology, which makes high grinding efficiency, low power consumption of ZJTL vertical mill grinding gradually replace inefficient, large power ball mill. The vertical mill is been transformed into by an internationally renowned Manufacturer of ZJTL Vertical Mill on the basis of LM vertical grinding mill, especially in processing wet sticky materials, such as chalk unique. To this end, the journalists paid a special visit on the manufacturers of vertical mill which has introduced the technology in the market - SBM companies and interview the relevant technical staff in R & D centers.
Through interviews, the journalists learned that ZJTL vertical grinding mill used in cement production line inherited a series of advantages of LM vertical mill ,such as: vertical mill small footprint, high grinding efficiency, easy to adjust the fineness, simple processing, low energy consumption, low investment, low noise, wear and tear small, less dust and so on. However, the processing capacity of LM vertical mill greatly reduced in some areas where put chalk as the main cement raw material not the limestone. Because the reason of origin, some areas of chalk is often hard frozen block of water as high as 23.56%, after a comprehensive water ingredients into raw mill is also up to 22%, while the integrated water standard normal limestone raw material should be less than 5% . So it has a high demands for the drying capacity of the mill, that is why so many manufacturers of equipments recommend using ZJTL3840 Raw Material Vertical Mill.
The main operating procedures of this machine are almost same with the ZJTL3230 Vertical Mill Using Instruction, just a slightly different in feeding and production. ZJTL3840 raw material vertical mill is equipped with more advanced drying system, a gas stove as a supplementary heat source of the mill, its air pressure is between the 1000-15000Pa, which make the system have greater flexibility to adjust the pipeline pressure distribution, to improve the operating conditions of the dryer ,also can control the hot air into the mill at 500 ℃. These fully enhance the humidity of the chalk and other cement raw material, thus contributing to improve the efficiency of grinding and exclude raw material impurities. For chalk and other sticky materials widely distributed, less limestone areas, ZJTL vertical mill greatly reduces the cost of cement production.
