What is the essential difference between the new compound fertilizer granulator and the drum granulator?
In the equipment of the organic fertilizer production line, the granulator may be a stirring tooth granulator, a compound fertilizer granulator, a drum granulator, a disc granulator, and a counter-roller extrusion granulator. Among so many granulator machines, each has its own unique advantages and performance. So what is the essential difference between the most widely used compound fertilizer granulator and drum granulator?

The new organic compound fertilizer granulator machine is suitable for organic fertilizer raw materials, livestock manure, manure, composting fertilizer, and the qualified granulation rate is as high as 80-90%. It is suitable for a variety of different formulas. The strength is higher than the disc and the rotating drum, and the ball rate is less than 15%. The particle size uniformity can be adjusted by the stepless speed regulation function of this machine according to user requirements. The organic fertilizer equipment granulator is most suitable for direct granulation of organic fertilizer after fermentation, which saves the drying process and greatly reduces the manufacturing cost.

The barrel of the rotary drum granulator adopts a special rubber plate lining or an acid-resistant stainless steel lining plate, which realizes automatic scar removal and tumor removal, and eliminates the traditional scraper device. It has the characteristics of high ball strength, good appearance quality, corrosion resistance, wear resistance, low energy consumption, long service life, convenient operation and maintenance, etc. Steam, gas ammonia or adding phosphoric acid or nitrogen solution, phosphorous ammonia slurry, heavy calcium slurry into the machine, complete the chemical reaction and heating compound fertilizer granulation process in the cylinder; or add a small amount of water to the compound fertilizer Cold granulation process. The material to be granulated is passed through the rotating movement of the barrel, and the barrel is fed into the barrel to produce rolling rotation, and the ball will be aggregated under a certain humidity and temperature to complete the ball making process.

Features of drum granulator:   
1. The ball formation rate is up to 70%, there is a small amount of returned material, the particle size of the returned material is small, and it can be re-granulated;   
2. Steam heating can be used to increase the temperature of the material, so that the water content of the material is low after the ball is formed, and the drying efficiency is improved;   
3. Use rubber engineering plastics as the inner lining, the raw materials are not easy to stick to the cylinder, and have the effect of anti-corrosion and heat preservation;   
4. Large output, low power consumption and low maintenance cost.
Advantages of rotary drum granulator: The main advantage is the use of steam to heat and adjust the humidity, which increases the temperature of the granulated material itself, reduces the granulation moisture, reduces the load of the dryer, and improves the work efficiency. The pelletizing rate of the drum pelletizer can reach 70%, and the equipment is easy to operate, flexible in work, and convenient to maintain. The equipment is lined with ultra-high molecular weight polyethylene (UHMW-PE), which eliminates the phenomenon of material sticking to the wall, reduces the labor intensity of workers, and greatly extends the service life of the equipment.

Whether it is a compound fertilizer granulator or a drum granulator, the performance of each granulator machine for fertilizer is unique. Each has its own scope of application and advantages. This requires our salespersons to clearly introduce their respective performance characteristics when introducing them to customers. Let customers clearly understand what kind of granulator they need.
