Granulation and Compaction

Since the 1930’s Sackett has been a trusted name in Process Systems. Over the years we have been awarded a slew of patents for technology and have built some of the most reliable and longest operating plants around the world. Sackett’s technology and expertise includes NPK granulation, organic/byproduct granulation, Ammonium Sulfate Compaction/Granulation and SSP Production and Granulation.


Our approach to designing and engineering allows us to ensure every requirement or need is met, and we work hard to maintain an ongoing partnership with our customers. For us, the relationship of upmost importance, and we’re happy to sit down and discuss our project approach at length. We have on site R&D facilities as well as the staff to offer process and basic engineering as well as complete equipment supply.

Sackett Process Systems Include:

  • NPK
  • Phosphates (SSP, TSP, DAP, MAP)
  • Ammonium Sulfate
  • Limestone
  • Organics
  • Minerals

Compaction Systems:

  • Material preheat
  • Product post treatment including rounding, drying, cooling, and coating

Thermal Processing

  • Moisture removal
  • Calcining

Our family of rotary drums includes granulators, dryers, coolers, coaters, kilns and calciners. Each drum is custom engineered to the process requirements.

Drum shells are made of a variety of materials, including carbon steel, stainless steel, inconel, and other high nickel alloys.

Sackett’s exclusive trunnions, designed with tapered roller bearings directly under the load point, provide superior dependability. Drives, both gear or chain, are engineered for smooth operation and dependability.
