cost of one set of the mill's replacement parts. Consider, for instance, a 100-horsepower hammermill that grinds corn. The cost of the mill's replacement parts breaks down to $0.01 to $0.05 per ton of ground corn, and the mill's energy cost per ton is $0.50 to $1.40. When the mill has a new screen, hammers, and pins, it yields 15 tph
Hammer mills operate on the basic principle that most materials will crush, shatter or pulverize upon impact. This is accomplished by a simple four step process: 1. Material is fed into the mill, typically by gravity. 2. Inside the grinding chamber, the material is repeatedly struck by flailing ganged hammers
Most newer hammermills are equipped with an air-assist system that draws air into the hammer mill with the product to be ground. Systems are designed to provide reduced pressure on the exit side of the screen to disrupt the fluidised bed of material on the face of the screen, thus allowing particles to exit through screen holes.
Hammer mills tend to yield less than 25% of particles below 150 μm. Because the end particle size of a milled material is determined by the screen size used on the mill, it is possible to use very small screens to attempt to get smaller particles. However, smaller screens are weaker and tend to break easily, which adds to equipment costs and ...
