2 Design features of MPS mills for coal grinding. Depending on the material to be ground, throughput rates of 5-200 t/h can be achieved in a fineness range between 1% R0.063 mm and 25% R0.090 mm. Thus, the MPS coal grinding mill device for fresh material is arranged in this area where the fresh feed is also mixed with the grits rejected from ...
MPS-89 pulverizers are rated for about 125,000 pounds of coal per hour and this is often referred to as the mill capacity. We prefer to discuss coal throughput as one of the three major components of capacity (Hardgrove grindability and fineness are the other two). Take one version of a typical

An overwhelming majority of coal fired boilers utilize a pulverized coal firing system. These systems utilize a pulverizer or mill to grind coal to a desired fineness and subsequently transport the coal to the burners using air as a transport medium. Air utilized to transport coal to the burners is considered "Primary Air".
