Manufacturing process for granulation and direct without fuel consumption of normal double or triple superphosphates.

摘要

Manufacturing process for direct normal granulation superphosphates, double or triple. The Ground phosphate Rock is mixed with sulfuric acid, Phosphoric Acid, or a mixture of both, according to Fabricate single superphosphate or Triple Double, in a reactor (1) at a temperature of 100 025 C For Normal or 60 025 C for triple.Moved by Gravity into a pre Curing Tape (2) where there is a scraping Blade (3) that Breaks into small Grains, The Solid Mass that has formed on the tape. Sent to a Rotary Drum Granulator (4) which introduces a small amount of sulfuric acid or Phosphoric acid and finely Ground Limestone, leaving particles coated Limestone.The Encapsulated Product passes the elevator (5) That Feeds the screens (6). The Thin conjunction with the thick ground in the Mill (7) are recycled to the Granulator.
