A Hammer Mill machine is widely used in the Pharmaceuticals and Food industries to cutting Materials into small fragments or small pieces (Also called Size Reduction). The main component of a hammer mill is a row of hammers that are hinged on a central shaft and contained in a strong metal container. Size reduction is achieved by Impact.

Abstract: In order to solve the problem of big noise during the working process of the hammer mill, and search for the main noise source and noise reduction method of hammer mill, the noise signals were collected and analyzed by the virtual instrument software LabVIEW and bench test on the hammer mill. The sound pressure level of the hammer mill was tested and analyzed in noload and load ...

Hammer Mills work on the principle that most materials will crush or pulverize upon impact using a three step operation. This operation can be very noisy and loud. 1. Material is fed into the mill's chamber typically by gravity. 2. The material is struck by ganged hammers (rectangular pieces of hardened steel) which are

Hammermills accomplish size reduction by impacting a slow moving target, such as a cereal grain, with a rapidly moving hammer. The target has little or no momentum (low kinetic energy), whereas the hammer tip is travelling at a minimum of 16,000 feet per minute (4,880 m/min) and perhaps in excess of 23,000 feet per minute (7,015 m/min) (high kinetic energy).
