Hammer mills are essential pieces of equipment in many different industries. Also called pulverizer mills, hammer mills are size-reduction machines that grind or crush various materials for industrial applications. They can process materials continuously or in batches and are used to grind everything from pharmaceutical powders, spices and cosmetics to rocks, minerals and recycling waste.

Understanding the working principle of hammer mills can help you choose the best equipment for your application. Learn more about the history of hammer mills, what hammer milling is and how you can benefit from custom machines built for your specific use case.

Hammer Mill History

People have used hammer mills for more than thousands of years. The earliest known record of one comes from the ancient Roman Republic in the palace of Mithradates VI Eupator, ruler of Pontus. This early form was a cog-and-axis water mill predominantly used to crush corn. Running water made mills more powerful and allowed people to crush hard materials with less effort.

Water mills then spread across civilizations and slowly evolved into the equipment industries use today. The water mill was eventually improved and adapted to mining purposes, particularly for crushing ore to release valuable metals and minerals.

The Industrial Revolution brought significant hammer mill construction changes. The steam-powered hammer mill was even more powerful than water-powered mills, which increased production and paved the way for new applications and manufacturing processes.

As hammer mills became more common, many different industries began using them in their production processes. Modern hammer mills offer improved efficiency, energy savings, productivity and workplace safety. 

Hammer Mill Machine Working Principles Explained

Almost all materials break down under impact. Imagine hitting a piece of chalk with a standard hammer. Hammer mills work using the same principle, except more hammers hit materials faster and with more force. A hammer mill supplies repeated impacts to crush or pulverize various materials &#; like ceramic, paper, glass, biomass, cement and some chemicals &#; in industrial settings.

Hammer mills come in various types and sizes, but there are a few essential parts of a hammer mill all models have:

• Feed chute

  : The process starts with the feed chute, which feeds particles into the machine. Most hammer mills have gravity-fed chutes, but some have feed screws to provide more control over how much material goes into the grinding chamber.

• Spinning drum

  : Inside the grinding chamber, multiple hammers are attached to a drum that spins. As the drum spins, the particles are crushed by repeated impacts with the hammers, walls and other particles.

• Sifting screen

  : A screen at the bottom of the grinding chamber sifts through the pulverized particles. Pieces that are small enough get through, while larger particles keep going through the hammers. 

• Discharge chute

  : Particles that are the chosen size or smaller exit the machine through the discharge chute. Hard, heavy materials generally discharge using gravity, but lighter or less dense materials often require pneumatic suction.

Hammer Mill Design Considerations

Though all hammer mills have similar parts, differences in the hammers, shaft speed and screen size can change the finished particle size. You also want to consider a mill's capacity when looking at various design options.

Hammers are available in several shapes and sizes. They are typically made of hardened steel and are rectangular, though they are also available with knife or impact edges. How large the hammers are and how many of them are on the drum affect the final material size. The material size and type also affect the ideal hammer. For example, hammer mills called lump breakers feature a fixed comb rather than swinging hammers. This type is for removing clumps in materials that have already been crushed into a powder and would not be suitable for large, hard materials like coal.

How fast the drum rotates around the shaft also affects the finished particle size since faster speeds increase the impact force the hammers have on the material.

The screen determines how large particles can be to exit the grinding chamber. For example, circle screens are best used with lightweight components like sawdust, grass and spices and are not suitable for sticky materials. Other types of screens include rasping screens and striated screens.

Generally, larger or more hammers, a faster speed and a smaller screen create a finer product, while smaller or fewer hammers, a slower speed and a larger screen create a coarser product. You can adjust these and other components individually as needed to produce your desired particle size.

Hammer mill capacity depends mostly on the raw material. A product like flour might move quickly through a lump-breaking hammer mill, so a smaller capacity may suffice. A harder, larger product like gravel might require larger equipment to produce the same volume of final material since it would move through the machinery more slowly. The type of hammers and the number of hammers in the grinding chamber can also affect mill capacity.

Custom Hammer Mill Benefits

Hammer mills have a relatively simple working principle, which means they can easily be modified or built to exact specifications. Designing a custom hammer mill built specifically for your applications comes with several benefits:

• Time and energy savings

  : A custom hammer mill can crush or grind materials more efficiently than standard equipment, saving your company time and energy.

• Cost savings

  : Investing in a custom hammer mill can also save money over time compared to the cost of using toll grinding services to have materials crushed by a third party.

• Continuous operation

  : A well-designed hammer mill system can run continuously, so you do not need to wait to receive crushed materials. Continuous operation can increase output and improve productivity.

• Easy maintenance

  : Removeable door covers and accessible parts make cleaning and repairing custom hammer mills simple and easy.

What is hammer mill machine?

A hammer mill is a machine used in the pharmaceutical and food processing industries. Its purpose is to crush, pulverise, shred, grind, and reduce material to suitable sizes.The hammer mill consists of a series of hammers (usually four or more) hinged on a central shaft and enclosed within a rigid metal case. It operates by producing size reductions through impact. In a hammer mill, the material you want to grind is hit by fast-spinning rectangular pieces of tough steel (called ganged hammers) inside a chamber.

What is the working principle of hammer milling?

The way a hammer mill works is based on a straightforward process. The rotor, which contains the hammers, is spun at a high speed inside the drum while material is fed into a feed hopper. The feeding process can depend on the design of the machine, which may use gravity or a metered feeding system.

The materials are crushed or shattered by repeated hammer impacts, collisions with the walls of the grinding chamber, as well as particle-on-particle impacts. A screen is fitted at the bottom of the mill, which retains coarse materials while allowing properly sized materials to pass as finished products.

What are the advantages of hammer milling?

Hammer milling offers several key advantages such as:

• Cost-Effectiveness: Hammer mills are cost-effective machines with low energy requirements for operation, which saves costs.
• Versatility: Hammer mills can handle various types of feedstock using screens of different sizes. They are versatile in the sense that speed and screen can be changed based on milling requirements.
• High Reduction Ratio and Capacity: Hammer mills have a high reduction ratio and capacity, irrespective of whether they are used for primary, secondary, or tertiary grinding.
• Space-efficiency: Hammer mills occupy a small space, making them suitable for areas with space constraints.
• Easy Installation and Dismantling: They are easy to install, operate, dismantle, and clean up.
• High Angular Velocity Grinding/Crushing: Hammer mills can grind or crush different types of materials at high angular velocity.
• Uniform Particle Size: Because of self-characterisation, hammer mills provide typically varying size distributions with the fewest fines.

These advantages and benefits make hammer milling a popular choice in various industries, including pharmaceutical, food processing, cosmetic, and construction sectors.
