Inorganic Fertilizer Systems
FEECO started its business in 1951 offering fertilizer granulation systems using inorganic raw materials. Today, we have refined the process over and over to provide you with a state-of-the-art system for your granulation needs. We offer two basic types of fertilizer granulation systems, tumble growth granulation and pressure granulation. The best process for you depends on your raw materials and product requirements.

The tumble growth granulation systems are a classical approach to fertilizer granulation using a rotary drum or pelletizing disc to form the granules, followed by a drying, screening, and recycle circuit. This system is very flexible and allows the use of liquid raw materials (i.e. sulfuric acid, phosphoric acid, ammonia, etc.) and reactions of materials to form granules.

The pressure granulation systems consist of a double roll compactor to make sheets of the material, followed by a crusher and granulator to break the sheet up into fertilizer size pieces, screening and recycle. This process does not typically require the addition of liquids or the need to dry.

Some of the systems and processes we offer include:
	DAP (di-ammonium phosphate) and MAP (mono-ammonium phosphate) NPK Grades Potash (KCl) Ammonium Sulfate TSP (triple super phosphate) and SSP (single super phosphate) Urea Pipe Reactor Grades Soil Conditioners (limestone, gypsum, etc.) Micronutrients (Zinc Sulfate, Magnesium Sulfate, etc.) Animal Feeds - DCP (di-calcium phosphate), MCP (mono-calcium phosphate), and DFP (de-flourinated phosphate)

NPK Granulation

Utilizing High Urea

FEECO International installed its first NPK Granulation plant in 1953 for Agway Fertilizer Company at Lyons, New York. The following year complete battery limit NPK granulation plants were engineered, designed, fabricated and installed world wide. FEECO has been able to stay in the forefront of NPK urea technology by working very closely with both equipment suppliers and customers throughout the world and is indebted to IFDC for its assistance in urea technology. As the fertilizer industry expands and world wide awareness increases about the agricultural and economic benefits of high urea NPK fertilizers FEECO has made a commitment to build on its long standing expertise and maintain its leadership in the design, fabrication and supply of fertilizer based products.

The TVA Pipe Reactor System - An important development in energy and cost reduction in the modern MAP (Mono-Ammonium Phosphate) and DAP (Di-Ammonium Phosphate) fertilizer processing plants.

FEECO has been leading the industry in modernizing the Pipe Reactor design. Starting with a complete review of all existing equipment and servicing pumps, meters and fluid lines, a complete proposal will be submitted incorporating the pipe cross reactor into your new or existing facility. Your modernized plant will be even more competitive providing a 90% MAP, and 30% DAP energy savings into your improved facilities. Features of the Pipe Reactor include:

Heats of reactions utilized to remove moisture from product
Increases productivity
Lower production costs
- Formula cost savings
- Less fuel consumption (90% MAP, 30% DAP)
Lower moisture content in product to the dryer
Lower recycle rate
Better product
- Harder Granules
- Granules more uniformly sized
- Results in less dust
- Better chemical analysis
- Homogenous product particles eliminate NPK segregation during handling and shipping
