Fertilizer manufacturing requires strict dust control to protect both personnel and equipment. At Eolter, we design robust filtration systems resistant to corrosive environments, ensuring efficient particle capture and compliance with the most demanding environmental regulations.
Our filtration systems are designed to handle the specific characteristics of dust, airflow, and chemical conditions in the fertilizer sector. This way, we optimize filtration efficiency even in facilities with high operational demands.
We develop filtration systems designed to protect critical equipment in the fertilizer industry, such as compressors, fans, and pneumatic systems. Our solutions minimize mechanical wear caused by dust, ensuring continuous and efficient operation for your activity.
We design each model to match key parameters such as type of dust, working temperature, humidity or particle load, which allows us to guarantee efficiency and durability in our equipment.
Emission source
Typical particle size range (µm)
Main characteristics
Reception and crushing of raw materials
20 – 500 µm
Coarse dust with a significant fraction >100 µm; hard and abrasive particles (phosphate rocks, urea, nitrates, sulfates).
Dryers and granulators
1 – 100 µm
Fine dust, mix of hygroscopic salts (urea, nitrates, sulfates); tendency to clump with moisture.
Coolers
5 – 150 µm
Broken product particles, highly abrasive, risk of buildup.
Sieving and fines recirculation
10 – 200 µm
Heterogeneous dust; significant respirable fraction (<10 µm).
Transport and storage (silos, conveyors, hoppers)
20 – 200 µm
Hygroscopic dust, risk of caking; may contain corrosive chlorides and sulfates.
Bagging and bulk loading
2 – 50 µm
Fine and corrosive particles; high proportion of respirable fraction; risk of environmental contamination.
Bag filters capture dust generated at different stages of the production process by passing contaminated air through filter bags. Solid particles remain trapped on the fabric surface, while clean air is released.
They can retain fine and coarse particles, including mineral dust, chemical compounds, and corrosive particles typical of fertilizer manufacturing.
They are used in stages where dust emissions are generated, such as crushing, mixing, drying, and packaging, as well as in processes involving handling of raw materials and final products. For each client, we evaluate the phases of the process that require them.
Yes, bag filters allow recovery of valuable dust that can be reincorporated into the process, minimizing losses and optimizing production efficiency and costs.
Service life varies depending on the filter material and operating conditions, but generally filters are designed to provide long-lasting and reliable performance for several years with proper and periodic maintenance.
Dust emissions in fertilizers are regulated by standards such as the EU Industrial Emissions Directive (IED) and EPA standards, which limit PM10, PM2.5, and specific compounds. Filters must ensure strict compliance to protect health and the environment.
