Hummer mill

What is a Hammer
A hammer mill is a
rock crusher that
employs a rain of
hammer blows to
shatter and
disintegrate a variety
of materials. Hammer
mills produce a
finished product size
that is dependent upon the following criteria:
Openings in perforated screens or grate bars
Number, size and type of hammers
Grinding plate setting
Rotor speed
Hammer mill Industry & Application Usage
Agricultural Industry: Common applications include
crushing animal tankage, animal feed, grains, and
agricultural limestone
Energy Industry: Reduce the size of materials such as
coal, corn, bagasse, wood, corn stalks, biomass and
biofuels, and more
Aggregate Industry: Common materials that hammer
mills can finely crush include gypsum, shells, rock and
Industrial Applications: Hammer mills can reduce the
size of gelatin, salt, meat and fish scraps, and more
Features & Benefits
Large opening for flexibility
Fully lined crushing chamber for longevity
Liners are bolted for easy change out
Grate bars and screens for accurate product sizing
that are easily replaceable
Hammers or rings allowing flexibility
Forged alloy steel and extreme duty shaft allowing
reduced vibration and longer bearing life
Positive lock housing for extra security from blow
outs and dusting
Adjustable grinding plate for process control
Multiple rotor configurations to suit any material
Large discharge opening
A hammer mill is a mill whose purpose is to shred or crush
aggregate material into smaller pieces by the repeated
blows of little hammers. These machines have many sorts
of applications in many industries, including:
Ethanol plants (grains)
A farm machine, which mills grain into coarse flour to
be fed to livestock
Fluff pulp DE fiberizing
Fruit juice production
Grinding used shipping pallets for mulch
Milling grain
Sawmills, size reduction of trim scrap and planer
shavings into boiler fuel or mulch
Shredding paper
Shredding scrap automobiles (see automotive
shredder residue)
Shredding yard and garden waste for composting
Crushing large rocks
In waste management
