Features and processes

1. Raw material requirements: The moisture content of raw materials is generally required to be low, usually around 10-15%.

2. Equipment: The main equipment includes flat die granulator, ring die granulator, etc.

3. Operation steps: raw material crushing - proportion mixing - drying treatment (reducing moisture) - granulation - cooling - screening

Advantages

1. Low cost: Since no or only a small amount of drying equipment is required, the overall equipment investment and energy consumption are relatively low.

2. Simple operation: The process flow is relatively simple and easy to operate and maintain.

Disadvantages

1. Particle quality: The particles may not be uniform enough, and the strength and density are relatively low.

2. Water solubility: The water solubility of the particles is not as good as wet granulation.

Applicable scenarios

1. Applicable to small or medium-sized organic fertilizer production enterprises.

2. Applicable to situations where the moisture content of raw materials is low.

3. More suitable for projects with limited budgets. Dry granulation is suitable for situations where the moisture content of raw materials is low and cost control is strict.
