Why do you need a hammer mill when making pellets?

A hammer mill is used to crush corn stalks, straw, peanut shells, bean stalks, firewood and other agricultural waste. To avoid burning of these agricultural wastes and help to protect the environment. Respond to the call of reducing emissions and effectively develop renewable energy. The machine performance is reliable, easy to operate and convenient. The device deal with a wide range of raw materials, can be adapted to corn stalks, straw, peanut shells, bean stalks, firewood and other wastes.

Working principle

The machine through the high-speed hammer crushing the material into the crushing chamber, under the action of centrifugal force, the crushed powder under the rotor centrifugal pressure and fan suction sent through the mesh. This process is repeated for the powder particles not passing through the screen until they are emitted through the screen.

What is a hammer mill for?

Hammer mill is a pellet machine supporting ancillary equipment. Crushing before granulation is a process that many workers adopt. It is a necessary equipment for large, medium and small feed mills, wood pellet plants and some small-scale rural farming plants.
A hammer mill is mainly used for crop stalks, branch and other plant straw chopping processing, it can also be used for a variety of crop straw and forage shredding. The complete set of equipment is mainly used for the chopping of biomass such as cotton stalks, bark, branches, corn stalks, straw and so on. The finished products can be used for power generation, paper making, granulation and refining alcohol.
Crushed agricultural plant debris can be used as make organic fertilizer, fuel, biomass pellet, paper and other ways. The device turns a large number of green waste into treasure, not only create a new economic value, but also protect the environment, improve the condition of soil, and get good social benefits.
Hammer mill can be used with feed pellet machine. And as a professional pellet machine manufacturer, GEMCO also suggests you that smash is the first step of granulation work.
Some people may ask why, let me tell you
  • Crushing the material through the mill, you can effectively improve the granulation of materials.
  • Raw materials through the smashing process can improve the digestion and absorption of animal nutrition, reduce the adverse effects on digestion.


  • The product is designed reasonable, manufacturing quality and reliable, with a simple structure, easy operation, small size, less space, labor-saving, energy-saving .
  • The design of fully automatic control of electric heating device, the material can be adjusted dryness and humidity to ensure the stability of the material forming, improve work efficiency.
  • The main parts of the hammer mill using a special treatment wear-resistant material , it can be continuously working and particular durable.
  • For a variety of biomass raw materials (corn stalks, wheat straw, cotton rod, straw, rice husk, peanut shells, corn stalk, branches, leaves, sawdust and other agricultural crops as raw materials).

Advantages of GEMCO hammer mill

  • The machine can be used for both of coarse grinding and fine grinding.
  • The amount of feeding can be automatically controlled.
  • Twice strike technology is adopted in the grinding chamber.
  • Using direct-connecting drive and reasonable design about the space between hammer and screen.
  • The feeder is equipped with automatic deironing device.
  • Using interlaced drain hole screen to ensure smooth discharging.
  • By changing the hammer screen with different diameter, the machine can achieve the different fineness.
  • The fast start door opener and flexible press screen structure make it easy to change the screen and convenient to operate and maintain.
