Coal mill pulverizer in thermal power plants - SlideShare. Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance.
The hammer mill is a power mill making use of a high-speed rotating disc, which is stationary to a number of hammer bars that move superficially by a centrifugal force. The machine was made effective with a one horsepower electric motor, and the efficiency was found to be 92.9% after testing was done with dried maize.
a) Design of the Hammer Mill Machine A small-scale hammer mill was designed, as shown in Figure 1. The designed hammer mill machine is comprised of the prime mover, the milling chamber, the inlet, the grits outlet, the suction fan, and the cyclone separator.
