Difference between Pin Mill and Hammer Mill

Both pin mill and hammer mill are used for size reduction and grinding, they have distinct differences in terms of operation, design, and applications. Pulverizer Pin Mill Grinder Machine for salt, red chili, and spices operate with rotating pins or discs, impacting particles to achieve size reduction, while hammer mills utilize rotating hammers to pulverize materials.

The pin mill and the hammer mill are two frequently used machines in size reduction and grinding procedures. These devices are widely utilized in a number of sectors, including the production of chemicals, food, and pharmaceuticals. Both the pin mill and the hammer mill are used to reduce the size of materials, but they operate very differently and have different designs and uses. We shall examine the differences between the pin mill and the hammer mill in this essay, highlighting their distinctive qualities and uses.

Operation Differences between Pin Mill & Hammer Mill:

The way a hammer mill and a pin mill operate is very different. A pin mill, also called a pulverizer pin mill grinder, works by impacting and reducing the size of particles with a sequence of revolving pins or discs. Through a feed inlet, the particles are introduced into the grinding chamber where they are impacted by the rotating pins and fragmented into smaller bits. The pins’ speed and arrangement can be changed to produce the appropriate particle size.

On the other hand, a hammer mill works by rapidly rotating a series of hammers to pulverize materials. The feed material is broken up into tiny pieces as a result of the hammers’ impact. The size of the perforated screen at the bottom of the grinding chamber determines the size of the finished product. Hammer mills are multipurpose devices that may process a variety of materials, such as grains, spices, and wood.

Design Difference:

A pin mill’s design and a hammer mill’s design differ greatly as well. A disc or rotor with pins or pegs sticking out of it is the basic component of a pin mill. High-speed rotation of these pins or pegs produces impact pressures that degrade the substance. Some pin mills feature straight pins, while others have pins arranged in a helical pattern. The configuration of the pins might vary. Different grinding processes and particle size distributions are possible with this design variant.

In contrast, a hammer mill consists of a rotor with hammers attached to it. High-speed rotor rotation occurs while the material is pounded and ground to a powder by hammers, such as corn cob. Depending on the application, hammer mills can be fitted with a variety of hammers, including stiff or swinging hammers. The final product’s particle size distribution depends on the hammer design and screen size.

Applications of Pin Mills and Hammer Mills:

Due to their distinct qualities and capacities, pin mills and hammer mills are used in a variety of sectors. In the pharmaceutical sector, pin mills are frequently used to grind dry or wet substances like medicines, vitamins, and minerals. Additionally, they work well for grinding chemicals, pigments, and culinary items like sugar and spices.

Contrarily, hammer mills are frequently employed in the agricultural and food processing sectors. They are frequently employed to grind grains into animal feed and flour. The wood industry can also use hammer mills to grind wood chips into smaller pieces for pelletizing or briquetting operations. Additionally, hammer mills can be used to recycle materials like cardboard, paper, and plastic by pulverizing them.
