NPK Compound Fertilizer Rotary Drum Granulator With 15-20 TPH

Introduction of Drum Granulator

Rotary drum fertilizer granulator is one of the critical machines in compound fertilizer production line. It is applied to cold,hot granulation and quantity production of high,medium or low consentration compound blending fertilizer. The granulating method is rolling round fertilizer particles in wet granulation. With water or vapour added, the original fertilizer in rotary drum are blended uniformly and become humid, during this process, the fertilizer reacts and by way of the liquid environment and rotation in drum, the fertilizer particles squeeze each other and roll into fertilizer particles.The formed fertilizer particles are of 3-4mm.

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

Structure of Drum Granulator

--Granulator bracket. The whole rotating part which bears large force is supported by bracket, therefore it adopts medium carbon steel plates,channel beam material which are welded and satisfies strict quality standard.
--Drive part. The gear frame is welded of high quality channel beam. The main motor in gear frame and reduction gears are both ISO National Free-inspection Product. Motor drives belt sheave,trianguler belt and reduction gears and offers power to granulator.
--Large gears. Fixed on granulator and meshes with small transmission gears to drive the whole machine working in the opposite direction. High-tech wear-resisting materials extends granulator service life.
--Rolling belt. Fasten on both sides of granulator for supporting

Applications of Drum Granulator
