The fertilizer crusher is a core piece of equipment in an organic fertilizer production line. Its processing directly affects the quality of the final product and production efficiency.
1.Raw Material Pre-Treatment Stage
Moisture Control: Keep material moisture content between 30% and 50%. Too dry creates dust; too wet reduces crushing efficiency.
Impurity Removal: Remove hard impurities like stones or metal manually or mechanically.
Initial Crushing: Break down large chunks to reduce the crusher’s workload.
2.Core Workflow
Feeding System: A conveyor belt feeds material evenly into the crushing chamber.
High-Speed Crushing: The rotor spins at 1,500–3,000 rpm, using hammers or blades to strike materials.
Screening: Crushed material passes through a sieve (usually 3–10mm holes).
Recycling: Oversized material stays in the chamber for further grinding.
3.Key Process Control Points
Speed Adjustment: Lower speed for fibrous materials; higher speed for brittle ones.
Sieve Selection: Choose sieve hole size based on required particle size.
Temperature Monitoring: Keep bearing temperature below 75°C to avoid overheating.
Current Monitoring: Unusual motor current may indicate blockage or malfunction.
4.Finished Product Quality Standards
Uniform particle size: ≥90% passes through the target sieve. No visible unprocessed chunks. Fibrous materials ≤5mm in length. Moisture content variance within ±2%.
By properly controlling process parameters and strictly following procedures, the fertilizer crusher can maintain peak performance. This lays a solid foundation for subsequent steps like fermentation and granulation.
