What is Hammer Milling? Hammer milling is a high energy process of reducing particle size (comminution) by impact with rapidly moving hammers. The material is fed into the mill’s chamber through a feed chute, typically by gravity, where it is struck by rapidly rotating hammers that strike particles repeatedly until the particles are reduced to a size that can pass through a nearby screen.

hammer mills reduce material by two forces: impact & attrition Impact by the hammers is 27% more efficient. To increase impact force you need to increase the cutting edges in the mill.
Abrasive material grinding like granite or quartz ore, requires regular hammer mill maintenance. In less abrasive uses like breaking up and cleaning copper wire from motors or pulverizing printed circuit boards, the hammers and internal components last longer, reducing maintenance and wear.
Materials Used In Hammer Mill Screen. Keep in mind the screen or chain curtain isnt to limit top size material as in a hammer mill it acts as an anvil In the double counterrotating design as the one illustrated the shafts are supported on both sides as well The two independent chain rotors rotate in opposite directions forcing material quickly through the mill
The rotation of the hammer shaft causes the hammers 28 to throw out radially by centrifugal force; and the hammers strike masses of the material which have entered the relatively large primary crushing zone from the overhead feed chute, impacting them by direct blows against vhe breaker plates for a primary reduction.
