whereas the hammer tip is travelling at a minimum of 16,000 feet per minute 4,880 mmin and perhaps in excess of 23,000 feet per minute 7,015 mmin high kinetic energy. The transfer of energy that results from this collision fractures the grain into many pieces. Sizing is a function of hammer-tip speed hammer design and
A hammer mill, hammer forge or hammer works was a workshop in the pre-industrial era that was typically used to manufacture semi-finished, wrought iron products or, sometimes, finished agricultural or mining tools, or military weapons. The feature that gave its name to these workshops was the water-driven trip hammer, or set of hammers, used in the process.
