Rotary Drum Organic Fertiliser Granulator
Drum rotary granulation technology, uniform particles, suitable for large-scale production.
Rotary Drum Organic Fertiliser Granulator Introduction
The rotary drum organic fertilizer granulator adopts rotary drum granulation technology, which is suitable for large-scale organic fertilizer production. It can make organic materials such as livestock and poultry manure and straw into uniform particles through wet granulation.
Features and Advantages
After several years of optimization and improvement, the performance and stability of our company’s rotary drum granulator have become increasingly mature, with obvious advantages and characteristics:
Efficient granulation
Adopting horizontal roller design, the material is naturally formed into balls in the rotation, the particle size is 3-6mm (adjustable), and the uniformity is ≥95%. Hourly production capacity of 5-30 tons, 2-5 times higher than the disk / double roller granulation efficiency, suitable for large-scale production of NPK compound fertilizer.
Strong adaptability
Compatible with organic fertilizers (animal and poultry manure, straw), compound fertilizers (urea + ammonium phosphate) and industrial waste residues with moisture content of 20%-40%. Rubber lining + spiral platen design, handle high fiber (straw), high viscosity (molasses) materials without sticking to the wall.
Energy saving and environmental protection
Low rotational speed (9.5-17rpm) + large diameter drum (Φ1.2-3.2m) design, the power of 30 tons/h model is only 37kW, 40% energy saving compared with traditional extruder. Totally enclosed structure + micro-negative pressure system, dust emission <10mg/m³.
Durable and anti-corrosion
The cylinder is made of Q235B boiler steel + 8mm butyl rubber lining (acid and alkali resistant pH 3-11), fixed with 316L stainless steel pressure bar, with 50,000 hours of anti-scouring life (only 8,000 hours for ordinary carbon steel). Cleaning holes + vibratory discharge design reduces downtime to clear clogs by 50%.
Intelligent control
PLC + frequency control system, real-time monitoring of speed, humidity (20%-40% intelligent control). Beginner 30 minutes to start, daily maintenance only need to lubricate bearings, annual maintenance cost <3% of the equipment price.
Flexible configuration
We support customization of capacity (1-50 tons/hour), material and corrosion protection (rubber lining/plastic lining). We can also customize high humidity resistant models (85% humidity) and low temperature resistant models (-40°C), which are available worldwide.

Working Principle
Working Principle of Rotary Drum Organic Fertiliser Granulator
The drum organic fertilizer granulator drives the drum to rotate through the motor. The material rolls in the drum under gravity and gradually sticks into particles. The spray system adds an appropriate amount of water or adhesive to promote the granulation of the material. The particles roll and polish in the drum to finally form uniform and smooth particles.
Application Scenarios
The rotary drum granulator has high efficiency and high quality granulation performance and is widely used in various large-scale fertilizer granulation application scenarios.
