Replacing some of the coal by biomass is an effective way to reduce CO 2 emissions from pulverizedcoalfired power plants and integrated coal gasificationcombined cycle power plants. However, compared with coal, biomass has lower grindability in the existing roller mills and a lower calorific value per weight. The maximum biomass cofiring ratio for stable operation is limited by the design ...

The test device is designed like a roller table mill with, however, only one roller. Fig. 1Fig. 2 show a scheme and a sketch. The grinding table (1) is shaped like an annular trough and driven with the motor (2). The conical grinding roller (3) fits in the trough. The roller and its bearings are mounted at the lever system (4) with the spring (5).

The main drive shaft turns the table supporting the grinding ring, which in turn transmits the motion to the rolls. There is no metaltometal contact between grinding elements, since each roller rests on a thick layer of coal. Thus the maintenance is minimized. ... Mills with conical rolls are known as bowl mills. As the coal is ground between ...

Similar to the ring and ball mill, the vertical spindle roller mill uses large "tires" to crush the coal. These mills are usually found in utility plants. Raw coal is gravityfed through a central feed pipe to the grinding table where it flows outwardly by centrifugal action and is ground between the rollers and table.
