Conversion granulator and roller extrusion granulator are two commonly used granulation equipment, each with its own characteristics in terms of working principle, production efficiency, product quality, etc
Conversion granulator (disc granulator):
working principle:
The conversion granulator sends the mixed raw materials into the mold through a rotating disc (conversion), forming particles under the action of centrifugal force.
Production efficiency:
High production efficiency, capable of continuous production, suitable for large-scale production.
Product quality:
The shape of the particles produced by granulation is regular and the particle size is uniform, but due to the formation of particles during rotation, cracks or incomplete molding may occur.
Energy consumption:
The energy consumption is relatively low because it mainly relies on the centrifugal force generated by mechanical rotation.
Scope of application:
Suitable for producing various types of granular fertilizers, including organic fertilizers, compound fertilizers, etc.
maintain:
Maintenance is relatively simple, but it requires regular cleaning and replacement of worn parts.
Roll squeezing granulator:
working principle:
The roller squeezing granulator applies pressure to the raw material through a pair of rotating rollers, causing the raw material to be squeezed into strips between the two rollers and then cut into particles.
Production efficiency:
The production efficiency is also high, allowing for continuous production, and due to the extrusion process, the production speed is faster.
Product quality:
The granules produced by granulation have high density and hardness, with regular shapes, but may require additional drying processes to remove excess moisture.
Energy consumption:
The energy consumption is high because it requires significant pressure to squeeze the raw materials.
Scope of application:
Suitable for producing granular fertilizers with high hardness and requiring high density.
maintain:
Maintenance is relatively complex, requiring regular inspection and replacement of worn rollers, as well as maintaining equipment cleanliness.
In summary, the conversion granulator is suitable for producing granular fertilizers with regular shapes and uniform particle sizes, while the roller extrusion granulator is suitable for producing granular fertilizers with higher density and hardness. The choice of equipment depends on production requirements, raw material characteristics, and expected product quality.
