Compound Fertilizer Rotary Drum Granulator For Limestone Dry
Mineral Powder
Introduction of drum granulator
The rotary drum granulator is a granulating machine for making
materials into a specific shape. The main work principle is
pelleted by wet method. By adding a certain amount of water or
steam into the materials, the materials play full chemical reaction
after being humidified. Under certain liquid phase conditions,
extrusion pressure is generated by the drum rotating and the
materials agglomerated into balls under this pressure. The drum of
this machine is lined with special rubber sheet or acid-resistant
stainless, which can automatically prevent materials from sticking
to the drum wall without traditional scraper device. There is no
waste discharge in the production process. It has the advantages of
high yield, corrosion resistance and wear resistance.
Advantages of drum granulator
(1)High fertilizer particles rolling rate about 70%, less returning
fertilizer created,but can be regranulated.
(2)Vapour or water adding improves fertilizer temperature and creates
high quality fertilizer particles.
(3)Engineering plastics are used for inner lining, no stick to
liners,Anti-corrosion and thermal insulation.
(4)Large granulating capacity,low enrgy consumption and low
maintenance cost.
(5)Flexible fertilizer particles diameter according to different
formulation, processing procedure and raw materials.
(6)Super quality steel materials,strict quality requirements and
control.
(7)Low noise,stable performance;rational structure like shoveling
plates to clean drums.
Characteristics of drum granulator
The particle size distribution is centralized and easy to control.
High organic matter content. The granules produced are spherical.
Organic matter content can be up to 100 %, achieving pure organic
granulation.
The granulation has no edge, and the powder rate is very low.
Spherical particles have no acute angle after granulation, so the
powder rate is extremely low.
High efficiency. It is easier to meet the requirements of mass
production.
