mer mill operation but not for jet mills. Melting point and thermal instability. Jet mills can grind materials with low melting points effectively because these mills have intrinsic cooling due to compressed air expan-sion in the body of the mill. With the help of sweeping air, hammer mills may also be able to process materials with low
Hammer mills reduce the particle size of materials 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 traveling at a minimum of 4,880 m/min (~16,000 feet per min) and perhaps in excess of 7,015 m/min (~ 23,000 feet per min ...
Hammer Design The design and placement of hammers is determined by operating parameters such as rotor speed, motor horsepower, and open area in the screen. Optimal ham-mer design and placement will provide maximum contact with the feed ingredient. Mills in which the rotor speed is approximately 1,800
Operation. The grain is introduced to the mill via the hopper, the material flow must be regulated and even (optional feed mechanism required, for optimal results). In the milling chamber, hammers rotate at high speeds to pulverise the material in to particles small enough to be drawn through the screen by the fan.
