ATA - Fertilizers Used for Raw Materials, Salts and Minerals
In the world of fertilizers many materials are used: raw materials, salts and minerals coming form extraction and process industries, other directly from agriculture and food industry. The recipes are studied following the materials availability and commercial request. They are basically mixing plant with 20 different components, some of them with a dosage less than o,2% wich require a very precise dosing system.
Two kind of process are used:
- Batch process: each component is weight separately then mixed. By using this process, it's possibe to change the process and the mixing time and respect the requested recipes.
- Continuous process: all the operations are done at the same time. The dosing precision is lesser using this process, but the material flow rate is bigger.
