FEECO is the leading provider of fertilizer granulation equipment for both inorganic and organic systems. Our custom ammonium sulfate production equipment is relied on by the industry&#;s most notable players. All equipment is designed around the unique characteristics of ammonium sulfate for optimal processing and handling results.
Want more information on ammonium sulphate granular? Feel free to contact us.
Our custom granulation drums are the industry standard for high-capacity, reliable ammonium sulfate fertilizer production.
Drying and cooling are critical steps in producing a high-quality granular ammonium sulfate that can withstand handling, transportation, and application. FEECO provides the industry&#;s best rotary dryers and coolers for use in the production of granular ammonium sulfate.
Coatings take granular ammonium sulfate from a standard product to a premium one by reducing dust, decreasing the potential for caking, and improving flowability and handling. FEECO coating drums are the preferred coating device when looking to produce a uniformly coated product.
FEECO also provides a comprehensive line of bulk material handling equipment for all of your ammonium sulfate handling needs. We offer custom bucket elevators, belt conveyors, reversing shuttle conveyors, and steep incline conveyors, along with pieces to increase the flexibility of your handling system, such as belt trippers and plows, and belt feeders.
We can supply a single piece of handling equipment to fit into your existing process, or a complete bulk handling system as part of an overall process solution.
The FEECO Innovation Center is a unique testing facility where we can test your material at both batch and pilot scale in order to work out process variables and design commercial-scale units, as well as scale up the process.
The FEECO Innovation Center is well-equipped to suit a wide range of testing needs, including pelletizing, drying, and roll compaction. We can test on a single piece of equipment, or a continuous process loop.
We offer comprehensive testing services in four categories:
Feasibility/Proof of Concept: An initial, non-witnessed batch testing phase in which the possibility of creating a product is explored.
Proof of Product: A more in-depth batch testing phase in which more time is spent determining whether a product can be made to desired specifications.
Proof of Process: A continuous testing phase that aims to establish the equipment setup and parameters required for continuous production of your specific material.
Process/Product Optimization: An in-depth study to optimize your specific material&#;s characteristics and/or production parameters in an industrial setting.

FEECO provides a comprehensive offering of parts and service to keep your equipment running its best for years to come. This includes a variety of field services, process and equipment audits, spare parts, and more.
Ammonium sulphate is not just a fertiliser used in agriculture.
It is an industrial component also used as a flocculant, which is a substance that encourages flocculation, i.e. the combination or aggregation of suspended solid particles.
The flocculation process involves destabilising colloidal particles by adding the flocculant.
It also has all these industrial applications:
Ammonium sulphate is a salt formed by the reaction between Ammonia and Sulphuric acid. Commercially, it can be found in white to beige crystals or granules.
Its content is as follows:
It is the most accessible source of low-concentration Nitrogen, is widely used in agriculture, and is also a relevant component in the production of balanced fertilisation formulas.
It is widely applied directly to the soil as a single product
, is an excellent source of fertilisation
in crops which extract large quantities of sulphur from the soil,
such as forage crops, vegetables (cruciferous vegetables, onions and garlic), cereals (wheat and barley) and grasses (maize, sorghum and sugar cane), among others.
It mainly contains Ammonium (NH
4+) and Sulphate (SO
4-2), and it is an acid pH product that is recommended for application in limestone and alkaline soils due to its strong acidifying effect.
Its use as a fertiliser is due to the fact that the need for sulphur is closely related to the amount of nitrogen available for the plant. Therefore, Ammonium Sulphate provides a balanced supply of both nutrients.
In conventional agriculture, it is still used en masse, especially for less profitable crops and as an important source of Nitrogen accompanied by Sulphur, a precursor in its assimilation.
It is therefore not an organic fertiliser, as its process is obtained through synthetic transformations and, as such, is not covered by European organic farming regulations.
In the field, it is known as a good fertiliser used in both extensive and intensive crops with a dual action, as it provides two macronutrients added to its Sulphur content that promotes the physical and chemical conditions of the crop soils.
Optimising the dose and application to crops in the soil, Ammonium Sulphate is a very good source of supply of this element, and is easy to mix and use.
The form of Ammonium is usually quickly assimilated by crops, although in large volumes it can become phytotoxic to the plant.
In fact, in hydroponics, its use is limited to a maximum of 15-20% of the total fraction of Nitrogen, the remaining being 80-85% Nitric Nitrogen.
Inorganic soil sulphur is absorbed by plants mainly as anion Sulphate and, due to its negative charge, it is not attracted by soil clays and inorganic colloids;
Sulphur remains in the soil solution, moving with the water flow and, therefore, is easily leachable
. In some soils, this leaching accumulates Sulphur in the subsoil, making it usable by deep-rooted crops.
The risk of leaching is higher in sandy soils than in clay-textured soils.
Soils with low organic matter content (<2%) commonly have Sulphur deficiencies, and every one percent of organic matter releases approximately 6 kg of it per ha per year.
In plants, Nitrogen and Sulphur have a very close relationship in their nutritional role.
This is because both nutrients are constituents of the 5 proteins (amino acids) and are associated with the formation of chlorophyll (involved in the photosynthesis process).
The obtaining of Ammonium Sulphate as an industrial product is the transformation of Gaseous Ammonia (NH3), mixed with water vapour to create saturation, and the incorporation of Sulphuric Acid.
This controlled reaction is transformed into the mixture of Sulphur (SO4) and Ammonium (NH4), which, because it is attacked with an acid, one more Hydrogen (H) is added to the formula.
All the Nitrogen in this fertiliser is presented in ammoniacal form.
Although it is highly digestible by the plant, it should preferably be absorbed in nitric form.
Its behaviour in soil is good and, because it has a positive charge, it is fixed in the clay-humus complex and does not leach so much to deep fields (as the nitric form does).
The presence of nitrifying microorganisms (nitrobacter and nitrosomonas, among others) facilitates its transformation to nitric.
As it has an acid reaction, it is used to acidify soils with an alkaline pH and a high presence of non-soluble Calciums and Magnesiums.
In addition, the Sulphur incorporated into the fertiliser improves the availability of Nitrogen and has a synergistic effect in its assimilation.
