What is a Hammer Mill?

A hammer mill is a particle size reduction machine. These machines grind and crush material using continual, high-speed hammer blows. This internal hammer shatters and disintegrates the material. Mills can be primary, secondary, or tertiary crushers, allowing for a wide variety of applications.

What is the Finished Product Size?

The finished product size depends on a few variables of the machine:

  • Number and size of hammers

  • Rotor speed

  • Setting of the grinding plate

  • Size of the openings in the perforated screens 

Hammer mills are often used for crushing and grinding material to less than 10 US mesh. Learn more about size reduction options with our Particle Size Conversion Chart..

Hammer Mill Usage by Industry

Williams hammer mills are a popular choice when it comes to particle size reduction. While many use these machines as rock crushers and stone crushers, they offer more versatility. Some of the industries and applications that benefit from this machine are:

  • Agricultural industry: To crush feed, grains, and agricultural limestone into digestible particles
  • Energy industry: To reduce fuel sources such as coal, corn, wood, biomass, biofuels, and more
  • Aggregate industry: To crush and grind gypsum, shells, limestone, clays, and more
  • Recycling industry: To finely crush printed circuit boards, “meatballs” and light scrap fiberglass
  • Medical industry: To create fine powders to use in chemicals or pharmaceuticals

Traveling Breaker Plate Mills

The Traveling Breaker Plate Mill is a non-clog hammer mill. This engineering allows a Slugger Crusher to reduce rock, clay, shale and bauxite to ¾” or smaller. It can reduce wet, sticky materials to a size suitable for further refinement. Its self-cleaning breaker plates reduce maintenance and service costs.

Reversible Hammer Mills

This machine's name comes from its ability to reverse the direction of the rotor. This rotor supports the hammers, bringing fresh grinding edges into action. The reversible capabilities lower the frequency of servicing. Our reversible hammer mills increase production, double the life of your hammers, and reduce maintenance costs.

Rigid Arm Breakers

This type of hammer mill has rigid hammers rather than swing mounted. This design makes the machine effective for the pulverization of soft, fibrous, or bulky materials into fine powders. It is also suitable for the reduction of friables like coal. Each ridged arm breaker has many edges that can be indexed and presented as wear occurs.
