Raw Mill is the key equipment for secondary grinding after crushing. And it is suitable for grinding all kinds of ores and other materials, no matter wet grinding or dry grinding. Raw mill is mainly used in grinding raw materials and end products in cement plant. It is also suitable for various ores and other materials metallurgy, mine, chemical and construction.
In Cement plant, raw mill is used to grind the raw materials into the fine powder. During the working process, raw material should be evenly and continuously sent to the grinding chamber. The raw material which is too large to pass through the feed inlet of the mill is prevented from entering the grinding chamber. The air current of the entire system is a closed loop, and is circulated under positive and negative pressure.
The grinding rollers of Raw Mill in Cement Plant can be boom-type suspension grinding roller and flat-type suspension grinding roller. The former is suitable for grinding medium hardness materials, while the latter is mainly used to grind low hardness and medium hardness materials. The grinding roller bearings are equipped with oil temperature detection, which can detect the temperature of the grinding roller bearing in real time, so as to timely adjust the lubrication oil temperature.
The Raw Mill is also equipped with an automatic control system. Its functions include automatic start and stop, feed amount setting and crusher speed control. The operator can adjust the output voltage of the grinding system according to his needs through the panel. The sensor connected to the automatic control system is responsible for detecting the material level and sending a signal to the control system to adjust the speed of the grinding machinery.
The working efficiency of Raw Mill is very high and grinding accuracy is also very high. It is a highly efficient and energy-saving grinding equipment for cement production line. It plays an important role in improving the yield and quality of cement.
