hammer mill capacity calculations
Hammer mills : an engineering overview. What is it ? How it
A hammer mill drive must be equipped with a frequency converter in order to be able to control the speed and thus adjust the capacity and resulting fineness of the materials. 3.5 Product feed The feed to the mill must be controlled (at least roughly) by a dosing equipment such as a vibrating tube , a screw conveyor , or an airlock rotary valve .

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). 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

is frequently used to specify hardness. A hammer mill is typically good for grinding softer materials with Mohs hard-ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materi-als become very abrasive; therefore, they are not suitable for high-speed hammer mills.
