Fertiliser Screening Machines

EXAMPLES OF USE

Typical application examples of our screening machines for fertilisers are the following types of fertilisers and fertiliser granules:

Mineral fertiliser
Nitrogen fertiliser
Calcium ammonium nitrate
NP fertiliser
NK and NPK fertiliser
Ammonium nitrate
Ammonium sulphate
Fertilisers with urea

Phosphate fertiliser
Monoammon phosphate (MAP)
Diammon phosphate (DAP)
Triple superphosphate
Potash fertiliser
Potash sulphate
Crude potash salt
Potassium chloride
Lime fertiliser
Lime
Magnesium lime

Lime fertiliser
Burnt cold
Converter lime
Trace elements fertiliser
Selenium fertiliser
Mixed fertiliser
but also organic fertilisers such as compost

We will be glad to advise you on which screening technology is best suited for your fertiliser types. You can also use our SPALECK TestCenter, where we can screen and classify your fertilisers together.

What is screening technology used for in fertiliser production?

Quality & environmental protection

Screening machines in fertiliser production make an important contribution to quality assurance. They also help to ensure that the legal requirements for fertilisers are met. They are therefore mainly used for

Control and protective screening (impurities, lumps, adhesions)
dedusting of the fertiliser
Classification screening according to size
as granulate screening machines.

Construction and design of fertiliser screening machines

Modular design for your application

Different types of screening machines and machine configurations can be used for screening fertilisers. These include

Single deck flip flow screening machines
Double deck flip flow screening machines
Screening machines with wire cloth
Dedusting screening machines
Screening machines with special mesh or screening mats against abrasion
Screening technology with cover
Directly excited or linear vibrating screens

Reliable control and protective screening
Exact classification of fertilisers according to granule size
Clean screening cuts for highest end-product quality
Efficient and economical production processes
Good scalability for large volume flows
Adaptable to changing fertilisers

Optimised and adaptable to different granulate sizes

Classification of fertiliser

As a manufacturer of screening machines, we build the machines customised for your application purposes. In doing so, it is usually possible to enable product changes of granulate sizes planned in advance by adapting the screening machine.

An example of this is a flip flow screening machine. Its screening mats can be quickly adapted when the batch is changed.

For example, fertiliser granules with a grain size of 0-3 mm and 3-8 mm can be screened in one batch. For another type of fertiliser, for example, 0-2 mm, 2-6 mm and 6-9 mm. In this case, simply change the screening mats accordingly. You can find a video on how this works at www.spaleck.eu/videos.

Designed for high tonnages

Scalable production quantities

Our fertiliser screening machines are often designed for high tonnage. The material is usually very demanding. It can be sticky, moist and also abrasive. A typical processing quantity is 100t/h or even 150t/h. Of course, we also realise smaller or larger machines with our plant engineering.

FERTILIsER PRODUCTION – WHY QUALITY MATTERS

It is impossible to imagine modern agriculture without fertilisers. At the same time, environmental protection must be taken into account. For example, overfertilisation may not occur.

That is why modern technology is used in fertiliser production. Only thanks to their help is it possible to produce high-quality fertiliser economically.

We at SPALECK are partners of many leading fertiliser producers and develop reliable and selective screening technology together with them.

We invite you to come and see for yourself at our SPALECK TestCenter. We will be happy to test your fertilisers with you and find the optimum screening technology.
