Before buying anything, it is essential for you to collect all the necessary information about the equipment. It applies to a hammer mill also; if you want to get an appropriate hammer mill, you should know everything about it. In this blog, you will read about the working process, types, and applications of hammer mills so that you can easily choose an ideal hammer mill according to your needs.
Working Process of a Hammer Mill:
The way a hammer mill works is straightforward. Hammers installed on a horizontal or vertical shaft are housed inside a cylindrical steel drum. When the drum rotates, the hammers blow on the material that has been fed into it. The ground material is broken into little pieces and forced through screens that are positioned inside the drum in the correct sizes. There are hammer mills without screens that employ air to distinguish between large and small-sized particles.
These hammer mills are used to crush materials in the primary, secondary, or tertiary stages. Depending on the application, hammer mills come in a variety of sizes and power capacities. Electric motors with a capacity of more than 2000 to 5000 horsepower are used in industrial hammer mills.

Types of Hammer Mills:
Gravity Discharge Industrial Hammer Mills:
The swinging hammers in these hammer mills are fixed to a shaft. Both hammering application and particle-on-particle force are used to reduce the particle size. These mills are known as bottom discharge or gravity discharge hammer mills because the discharge occurs from the bottom and is subject to gravity. These mills are used to crush materials such as ceramics, dry chemicals, and glass.
Full Circle Screen Hammer Mills:
A 300-degree rotating screen on these industrial hammers enhances particulate evacuation. It works well for lightweight components that don't need to be initially ground. Spices, grasses, and other materials are hammered in these mills.
Horizontal in-feed Hammer mills:
These mills are used to grind heavy particles because of their aggressive operation. These hammer mills have trim scrap grinders and pallet grinders for performing tough industrial grinding.
Lump Breakers:
Lump Breaker differs significantly from comparable hammer mills in both design and functionality. This type has a small fixed hammer structure on the shaft rather than swinging hammers. This hammer mill's objective is to smooth out the powder or paste, not to diminish the particle size. Comb refers to the hammer construction on the shaft. To reach the desired particle size, the particles are made to pass through the comb.

Applications of Hammer Mills
Production of Powder:
Various types of hammer mills are employed in the pharmaceutical and chemical industries to produce the powder. A middle-grade powder is produced after all necessary materials are crushed in hammer mills. When employing hammer mills, grain size can be almost precisely measured. These mills are only limited because no sticky materials can be pounded since they might adhere to the perforated screen.
Grinding of Legumes, Grains, & Food Products:
In the food processing sectors, several kinds of legumes are ground using hammer mills. They primarily function as grinders for soy, nutshells, groundnuts, and various kinds of beans. Hard nutshells are removed using hammer mills that use gentle hammer blows.
Material Size Reduction:
Hammer mills are used in the pharmaceutical industry to micronize materials. The dosage of the therapeutic grains must precisely fit inside the capsule packing. As a result, before packaging, the grains are ground into a fine powder using hammer mills.
