Meat grinder blades expand at a such(prenominal) slower speed than blade grinders, which may may rotate at speeds as high as 20,000 to 30,000 rpm.



[citation needed] Blade grinders also resemble industrial blade (propeller) mixers, which like meat grinders rotate at much slower speeds. Unlike blade grinders, these mixers do not alter (break, cut, shred, macerate, pulverize) the material being mixed.[3] The high speed of rotation of blade grinders is necessary to achieve their cutting action.
