Biomass Pellet Mills

Each Farm Feed System Biomass Pellet Mill is a bespoke design to meet a Client’s particular needs

Biomass Pellet Mills

Typically, the Farm Feed System Biomass Pellet Mill equipment consists of:

  • Raw Material Hopper(s)
  • Hammer Mill
  • Transfer Auger
  • Control Hopper
  • Pelleting Mill
  • Vibratory Dust Extraction System
  • Inclined Conveyor
  • Bagging Line
  • Control Panel


  • Plant capacity range 100kg to 1000kg per hour (larger is possible)
  • Fully automated process
  • Operator supervision 2 to 3 hours per day
  • Double shift capability
  • Savings on waste disposal costs

For Biomass Pellet Mills to operate successfully there are three imperatives:

a. Moisture content of raw materials must be kept below 16%

To produce a quality pellet, massive mechanical pressure is required to create binding of the raw materials. However, the greater the moisture content, the poorer the pellet quality. Additionally, friction within the Pellet Die creates heat and if the Die temperature exceeds approximately 90°C, moisture will begin to gasify. Experience tells us that if moisture content of raw materials exceeds 16%, pellet quality will begin to suffer.

b. Particle size

Material for pelleting should be of a consistent particle size. Shavings will cause blockages in the feed mechanisms and larger bodies (chips and off cuts) can cause mechanical failures. If pelleting straw or reeds, it first needs to be chopped to the point where it will flow into a hammer mill. Sawdust with shavings and straw can be milled through a hammer mill (grinder) with a 6mm screen fitted. Larger bodies should be granulated or milled down to pass through a 6mm screen.

c. Sawdust/reed/straw mixes

Although it is possible to pellet many types of soft and hard woods through a single Die, compression is controlled through the addition of water and pellet binders. Different materials require different levels of additive. So if the materials being presented to the Pellet Mill are constantly varying, it will be very difficult to control pellet quality resulting in too soft or too hard pellets. The same principle applies to straw types or mixtures of straw and wood sawdust. However, if differing materials are presented in a consistent ratio and mix by way of a proportioner mill, additives can be adjusted to suit, and quality pellets will be produced.

Spares & After Sales support

Farm Feed Systems maintain a comprehensive range of spares for Biomass Pellet Mills. We hold stock of replacement die-rings and roller shells, a policy not followed by most other die-ring manufacturers.

Within FFS Pellet Mills is a total of 40 years experience with the components and equipment offered. This enables almost all customer queries and/or technical problems to be resolved with a simple telephone conversation.
