The operating principle of an MPS medium-speed coal mill is shown in Fig. 1. The raw coal enters the grinding parts from the coal chute. Raw coal is crushed into pulverized coal through the squeezing and grinding effect of the pressing force. Primary air enters the medium-speed mill through the air ring, and the pulverized coal is dried and ...
modification to its mill predecessor. Shortly thereafter, DBW became the first licensee of Gebruder Pfeiffer in Europe for coal applications. This particular mill was chosen because of DBW's successful track record - not only in their world-wide installation of 6 to 100 TPH MPS coal mills since the early 1960s - but also
for about 120,000 pounds of coal pulveriza-tion per hour: one an RP mill design (Figure 1) and the other an MPS design (Figure 2). Both mills have vertical spindles and horizontal grinding tables or bowls. In part one of this series, pulverizer capacity or throughput was described as being not sim-ply a static rating in tons per hour.
Today more than 2000 MPS mills are in operation throughout the world . MPS-type pulverizers have a wide range of capacities as well as the ability to dry higher moisture coals . Fig. 1 shows the air and coal flow path inside the mill and several important stages of operation of the MPS mill. Hot primary air enters the throat of the mill, which ...

In addition, moisture evaporation increases the primary air flow rate and conversely reduces the coal flow rate. Hence this paper focuses on CFD modeling of the MPS mill considering the effects of moisture evaporation and coal particle sizes on the primary air. The model serves as an important tool for achieving equal coal/air flow at …
