SIMS - Services - Tip Speed Calculator. Impeller Diameter. Motor Speed. Tip Speed. mm in. RPM. m/s ft/s. Feb 25, 2016 The hammer mill is the best known and by far the most widely used crushing device employing the impact principle of breaking and grinding stone. Thus far we have described machines which do a portion of their work by impact, but the only machine described in which this action plays an important role was the sledging roll type and particularly the Edison roll crusher

A common range of tip speeds seen in hammermills is commonly in the range between 5,000 and 7,000 m/min ( 16,000 and 23,000 feet per minute). When the tip speeds exceed 23,000 feet per minute, careful consideration must be given to the design of the hammer mill, the materials used in its construction, and the fabrication of all the components. Hammer tip speeds can vary because of equipment design and size-reduction needs. However, tip speeds generally range from 76 m/s to 117 m/s. Also, they mentioned that tip speeds are usually achieved at shaft speeds ranging from 2500 to 4000 rpm.
