The Core Role of Granulators in Production Lines

The granulation process is a key stage in organic fertilizer production, mainly achieving the following functions:

· Transforming powdered raw materials into granules, reducing dust loss during application

· Increasing product bulk density, lowering packaging and transportation costs

· Improving fertilizer physical properties, enhancing market competitiveness

· Facilitating control of nutrient release rate, improving utilization efficiency

How to Choose: Double-Die or Flat-Die?

When to choose ring-die granulator:

· Pursuing high output and large-scale production

· Raw materials mainly fine powder with low fiber content

· Need to produce pellets with exquisite appearance

· Strict requirements on pellet uniformity

When to choose flat-die granulator:

· Small to medium scale production with limited budget

· Raw materials contain more fibers or sticky substances

· Less demanding on pellet shape

· Emphasis on equipment operating economy
