Half-Wet Material Crusher
The half-wet material crusher occupies a crucial position in the crushing section of an organic fertilizer production line, serving as a bridge between the fermentation and granulation stages. Fermented and matured organic materials typically have a high moisture content and are prone to caking, requiring crushing and breaking them up before proceeding to subsequent screening, batching, and granulation processes. The half-wet material crusher, with its excellent adaptability to high-moisture materials, has become the mainstream configuration in the organic fertilizer crushing section and is widely used in various large, medium, and small organic fertilizer production lines.
Crushing Process
The crushing process in an organic fertilizer production line using a half-wet material crusher is typically a closed-loop cycle. The fermented and matured material is fed into the crusher by a loader or conveyor belt. The crushed material is discharged through a screen and enters a vibrating screen for grading. The qualified powder under the screen is sent to the granulation stage, while large pieces and insufficiently crushed coarse material are returned to the crusher for further crushing. For materials with high moisture content, dry materials can be added before crushing to adjust the moisture content, or a drying process can be added after crushing to ensure that the powder entering the granulation stage meets the required fineness and moisture content standards.
Process Advantages
Direct crushing of wet materials eliminates the need for pre-drying, shortening the process and saving drying energy.
Closed-loop circulation crushing ensures stable and controllable output fineness, providing uniformly sized qualified powder for granulation.
Self-cleaning equipment prevents material blockage, ensuring high continuous production efficiency and minimizing manual cleaning workload.
Low material temperature rise during crushing preserves the activity of beneficial microorganisms in organic fertilizer.
One crusher can be paired with multiple granulators, maximizing equipment utilization and making the overall line investment economical.
