GRANULATION METHOD AND SYSTEM

摘要

A granulation method may include feeding a graded powder into a granulator. The powder may have a particle size distribution (PSD) of at least 98% -115 mesh and at most 50% -200 mesh. The powder may have a PSD of at least 98% less than or equal to 4.2% of a median product particle size and at most 50% less than or equal to 2.5% of the median product particle size. The powder may have a PSD of between 40% and 80% between 3% and 6% of the median product particle size, between 5% and 30% between 2% and 4% of the median product particle size, and between 10% and 40% between 1% and 3% of the median product particle size. A liquid binder may be fed into the granulator. Wet granules may be discharged from the granulator and may have a moisture content of between 7% and 12%.
