High-pressure grinding rolls were first applied in the minerals industry in 1985 in cement plants. The main objective for the use of HPGR was the significant energy savings achievable. Today, they are also being used by diamond mines and for the communition of coal as well as for the grinding of slag, iron and chromium concentrates (Figure 4).get price
We have supplied vertical roller mills (VRM) for raw, coal, slag and cement grinding for several decades. The vertical roller mill is well known in the cement and power plant industries as the preferred mill for grinding of raw materials. It is increasingly used as a solution for efficient grinding.get price
To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.get price
The grinding operation is controlled by varying both speed of rotation of the grinding table and pressure on the rollers. Drying Immediate contact with the hot primary air feed evaporates any moisture contained in the ground coal particles, so that the desired mill outlet temperature is achieved.get price
