In an organic fertilizer production line, the mixer is key for getting raw materials blended evenly. Its efficiency directly affects the quality of later pelletizing and the whole line’s output. Here are the main things that affect a mixer’s production efficiency:
1.Raw Material Characteristics
Moisture Content: The best level is between 30% and 50%. Too high makes stuff stick to the walls; too low causes dust.
Fiber Content: Long-fiber materials like straw need chopping down to 3-5cm first to avoid tangling the mixing shaft.
Thickness and Stickiness: For thick, sticky materials, use a double axis mixer. Adding some bentonite can help it flow better.
2.Process Settings
Speed: Usually best between 20 and 40 rpm. Go slower for sticky stuff, faster for loose materials.
Mixing Time: 5-10 minutes is usually enough for a good mix. Mixing longer just wastes energy.
Loading Order: Add dry materials first, then wet ones. This helps prevent clumping.
3.Equipment Maintenance
Regular Cleaning: Clean off buildup from paddles and the drum wall at the end of each shift.
Lubrication: Add high-temperature grease to bearings every 500 hours of operation.
Replacing Worn Parts: Change paddles if they wear down by more than 5mm.
4.Automation Level
Automatic Feeding: Can cut manual handling time by about 30%.
PLC Controls: Allow precise setting of speed and mixing time.
Real-time Moisture Sensors: Let you adjust water addition instantly.
By optimizing these factors, you can often boost a fertilizer mixer’s blending efficiency by over 50% and cut energy use by 20%. Regularly check the equipment’s condition and set up a preventative maintenance plan to keep production running smoothly and steadily.
