Screening machines for phosphate fertilizers

Challenges in phosphate screening. Typical phosphate fertilizers are subject to specifications that allow particle sizes ranging from 2 mm to 4 or 5 mm (10 Me. to 5 Me.). In addition, these products are often expected to have a quality of more than 90 percent, which means that only 10 percent of the particles may be outside the specialized range.
