Dual stage mills feature two independently driven hammer mills stacked one over the other. Attrition Zone In a dual-stage hammer mill, there are really three phases of size reduction, due to what is known as the attrition zone. The attrition zone is the area created between the top rotor and bottom rotor of a dual stage hammer mill.

Samples of ground from each screen size and motor speed combination were analyzed for particle size and angle of repose (AoR). Particle size was determined according to the ASAE 319.2 2 standard method using a stainless-steel sieve stack (13 sieves), 15-minute sieve time, sieve agitators, and dispersing agent. The geometric mean diameter (d gw) and geometric standard deviation (S gw) of ...

The typical particle sizes that can be achieved with hammer mills is a D 50 between 150 μm and 600 μm. 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.

The Hammer Mill is widely used for coarse/medium grinding of minerals, foodstuffs, fertilizers, and chemicals. Raw materials as big as a few tens of mm are ground to an average particle size of roughly 0.5-2mm by the impact generated from the swing hammers traveling at circumferential speeds of 40-50m/s. The machine is also used often before the fine grinding process to increase capacity and ...

Large hammer mills can reach up to 20-50 t/h depending on the expected granulometry (more fine, less capacity ; coarser, larger capacity). Materials having a size up to 60 mm can be grounded to ~1 mm, while, if the feed is already finer (10 mm), hammer mills can reach sizes less than 500 microns.
