The disc granulator and drum granulator each have different characteristics and applicable scenarios.
A disc granulator is a common granulation equipment that produces spherical particles from raw materials through the action of rotating discs and centrifugal force. The disc granulator has the characteristics of automatic classification, small footprint, low cost, flexible operation, and easy observation. It is suitable for the granulation process of manufacturing a wide variety of materials with precise agglomerate size, especially suitable for small organic fertilizer plants. However, the disc granulator also has some drawbacks, such as low output of a single equipment, inability to seal the equipment, and high dust.
The drum granulator has the characteristics of large production capacity, long material retention time, and multiple processes simultaneously. It is suitable for granulating materials that are not easily granulated and is suitable for large-scale production.
The stock conversion granulator adopts various combination lifting devices. The dryer has undergone multiple technological innovations in the lifting device system. It adopts a new type of multi combination lifting device to overcome the wind tunnel phenomenon and heat of traditional dryers. High efficiency, reducing coal consumption by about 20%.
The reasonable equipment structure of the organic fertilizer equipment conversion granulator reduces the occupied area, has a large production capacity, and is easy to operate. Its technology is mature, high-temperature industrial, safe and reliable, energy-saving and environmentally friendly, greatly saving costs.
The advantages of a drum granulator are large production capacity of a single equipment, good sealing, no dust and exhaust gas leakage, easy setting of feeding and automatic control of water spraying, long residence time of materials in the cylinder, and high particle strength. At present, large and medium-sized fertilizer production plants all use drum granulation.
In practical applications, some manufacturers have connected disc granulators and drum granulators in series for secondary granulation, and have achieved good results. But whether it needs to be used together depends on specific production needs and conditions.
