Disc granulator, also known as pelletizer, pellet machine, spheronizer, or mud pellet machine, is a mature granulating technology with extensive applications across multiple industries. This versatile equipment serves fertilizer, chemical, pharmaceutical, food, and handicraft sectors, with specific naming conventions varying by industry application. Material construction options include carbon steel and stainless steel to meet diverse operational requirements.

The disc granulator employs centrifugal force technology for pellet formation through a comprehensive production workflow:

• Initial Fermentation: Livestock and poultry manure undergoes fermentation in specialized tanks with appropriate auxiliary materials to achieve complete decomposition
• Crushing and Mixing: Fermented organic materials are crushed to optimal particle size, transported to horizontal mixers for homogenization, then conveyed to granulator feed bins
• Feeding and Granulation: Powdered materials are uniformly fed into the disc granulator; automated moisture systems maintain optimal humidity levels; centrifugal force and disc friction create axial rolling action that forms uniform organic fertilizer pellets
• Drying and Cooling: Moisture-rich pellets move through drum dryers with heat conversion systems, then to coolers for temperature reduction before screening
• Screening and Coating: Drum screening machines separate qualified particles for coating processes; substandard materials return to crushing and mixing stages
• Packaging and Storage: Coated particles undergo automated weighing and packaging before final warehousing
• Dust Control: Comprehensive dust management through cyclone collectors or water curtain wet dust removal systems ensures environmental compliance
