When processing potassium-containing material into raw material for fertiliser granules, a consistent and clean feed stream is essential. In practice, the material regularly contains a coarse stone fraction of approximately 6 to 20 mm. This unwanted fraction adds no value to the subsequent production process and causes additional wear on the equipment.
At a processing facility for fertiliser granule production, the new MGM GS series grid screening bucket is being used successfully to separate this coarse stone fraction from the material efficiently.
Cleaner raw material for a better end product
By screening the material in advance, stones and coarse particles measuring 6 to 20 mm are removed from the raw material. This creates a more homogeneous product that is better suited for further processing into fertiliser granules.
A more consistent raw material results in a more stable production process, higher product quality and less unwanted contamination in the production line.

Less wear on the production line
Removing coarse stones in advance offers several benefits for the production equipment:
- Less wear on crushers, mixers and conveyor systems.
- Reduced risk of malfunctions and unplanned downtime.
- A more consistent material flow towards the production line.
- Higher-quality raw material for fertiliser granule production.
- Lower maintenance costs due to reduced strain on the equipment.

Developed for continuous operation
The MGM GS series has been developed for maximum operational reliability. Thanks to the use of Hardox wear-resistant steel and high-quality high-strength steel, the machine is capable of withstanding demanding conditions.
The easily replaceable wear parts allow for quick maintenance. This makes the grid screening bucket particularly suitable for continuous operation in industrial applications.
Flexible in use
The GS series is available with different grid openings, allowing the machine to be configured for the required separation size and application.
This makes the grid screening bucket suitable not only for the fertiliser industry, but also for a wide range of applications in the recycling, mining, earthmoving and raw materials industries.
Proven in practice
This application demonstrates that the MGM GS series is a valuable addition to the fertiliser industry. By removing the coarse stone fraction before further processing, the quality of the raw material is improved and wear on the production equipment is significantly reduced.
With the MGM GS series, you choose a robust grid screening bucket developed for high capacity, minimal wear and reliable operation under demanding conditions.
