Rotary Drum Granulator for Organic Fertilizer Production with High Granulation Rate Low Energy Consumption and Carbon Steel Construction

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 concentration 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.

• High fertilizer particles rolling rate about 70%, less returning fertilizer created, but can be regranulated
• Vapour or water adding improves fertilizer temperature and creates high quality fertilizer particles
• Engineering plastics are used for inner lining, no stick to liners, anti-corrosion and thermal insulation
• Large granulating capacity, low energy consumption and low maintenance cost
• Flexible fertilizer particles diameter according to different formulation, processing procedure and raw materials
• Super quality steel materials, strict quality requirements and control
• Low noise, stable performance; rational structure like shoveling plates to clean drums

The belt and pulley are driven by the main motor, and the driving shaft is driven by the reducer. The pair of open-gears installed on the driving shaft and the big gear ring fixed on the machine body are combined and work in opposite direction.

The materials are fed from the inlet and are made into particles with the drum rotating under certain conditions. The particles finally flow out through the outlet. With the continuous materials feeding and continuous rotating to achieve the mass production.
