The ultrafine ring roll mill is more energysaving. If the output and fineness are the same, compared with the Raymond mill, the system energy consumption of the ultrafine ring roll mill is one third of that of the Raymond mill. Moreover, the grinding pressure of the ultrafine ring roll mill on the material is also kg higher.
Obtained results indicate that grinding pressure, primary air (PA) temperature and mill motor current have a tendency to rise by increasing coal feeding mass flow rates for all used coal.
