Abstract. High speed hammer mills break particles suspended in gas by high velocity impact against a hammer surface. Assuming that the action is comparable to a stream stagnating against a surface, it is shown that the net mill power can be calculated and it is predicted that the power varies approximately proportional to the hammer speed cubed.

II. WORKING OF HAMMER MILL MACHINE When feed is delivered to the hammer mill crusher, it is prepared for cyclone furnace firing by being crushed into 1/4 inch or smaller size feed. Feed enters from the top and is violently thrown against the breaker blocks by the hammers. The final crushing is done between the hammer faces and the screen bars.

For hundreds of years, water mills have supported the local economies of Piedmont by contributing to the production of flour, textile fibres, timber, and metal agricultural tools. Since the beginning of the last century, and in particular after the 1950s, many artefacts have been abandoned. Nonetheless, hundreds of mills are still present in southern Piedmont, both in the plains and in the ...
