Abstract

The invention discloses a rotary drum granulator, which comprises a bracket and a cylinder. Two sides of the cylinder outer wall are respectively provided with a gear. A retaining riding wheel is respectively arranged below each gear, and riding wheels are disposed at the bottoms of the retaining riding wheels. The cylinder is also connected to a transmission device. The cylinder is internally provided with an oil and powder spraying device. Two ends of the cylinder are provided with a feed inlet and a discharge port. The rotary drum granulator provided in the invention has the advantages of reasonable structural design, convenient installation, and high compressive strength, and the obtained granules have high yield and are round and full. The rotary drum granulator is suitable for the production technology of compound fertilizers by urea based, nitro based, sulfur based, ammonization and other slurry methods, and its liner has self-cleaning and anticorrosion effects.

Description

technical field [0001] The invention relates to a granulator, in particular to a drum granulator for producing compound fertilizer. Background technique [0002] Drum granulator is a molding machine that can make materials into specific shapes. It is one of the key equipment in the compound fertilizer industry. It is suitable for cold and hot granulation and large-scale production of high, medium and low concentration compound fertilizers. Its main working method is granulation wet granulation, that is, through a certain amount of water or steam, the basic fertilizer is fully chemically reacted after the humidity is adjusted in the cylinder, and under certain liquid phase conditions, the rotary motion of the cylinder is used to make The extrusion force between the material particles is agglomerated into balls. [0003] The drum granulators currently on the market have the disadvantages of complex structure, inconvenient installation, low pelleting rate, and low granule ...
