2017-3-25  The design and placement of hammer is determined by operating parameters such as motor speed, prime mover in the screen, hammer design and placement that will provide maximum contact with the feed ingredient. Tip speed is the speed of the beater at the tip or edge furthest away from the rotor and is calculated by multiplying the rotational speed of the drive source (shaft rpm) by the circumference of the hammer tips as given by the equation A common range of tip speed seen in hammer mills is commonly in the range 5,000 and 7,000ft/min i.e. 16,000 and 23,000 ft/min is used while the lower value of 16000 ft/min is used for safety and the derive speed is 1800rpm.
