The industry covers the processing of salts and inorganic minerals into commercial form: crushing/milling, drying and classification, and—if required—granulation or compaction, as well as blending of N/P/K fractions.
Key parameters include particle size distribution, moisture content, bulk density, and granule strength. Major challenges include dust generation (ATEX), hygroscopicity and caking (especially chlorides), corrosiveness and abrasiveness of materials, and the risk of mixture segregation—hence the importance of selecting proper construction materials, anti-adhesive coatings, storage conditions, and matching particle-size fractions.
Key Specification
Process Chain
Raw material processing
- size reduction/milling, optional drying and classification
- (optional) compaction + crushing and screening, or drum/pan granulation
- coating with anti-caking or anti-dust agents
- storage and packaging (bags / Big-Bag / bulk)
Physical blends
- reception and storage of raw materials (silos/bins)
- dosing of streams (belt / hopper scales)
- drum or paddle mixing + coating
- control screening and particle-size correction
- packaging/dispatch, dedusting with dust recovery
Typical Line Components
- crushers and mills
- dryers/coolers
- screens
- drum/paddle mixers
