Hammer Milling Hammer Mills AVEKA

The first is to hit the material with a hammer and observe what happens. If it shatters, this is a good candidate for hammer milling. If it mostly sticks together in a mass, this is a less likely candidate. Better yet is to use a desktop mill for initial evaluation. If any fine particles are produced, there is a good chance the material will mill.

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.
