To ensure uniform mixing of raw materials in an organic fertilizer production line, the following aspects can be considered:

1. Raw Material Pretreatment: For larger, harder raw materials (such as crop straw), use a hammer mill or claw mill to crush the material to an appropriate particle size, generally 2-5 cm. Ensure the moisture content of the raw materials is within the appropriate range, generally between 40% and 60%.

2. Optimize the Mixing Process: To control the mixing speed and time of the organic fertilizer crusher, equip it with a variable frequency speed control system. Flexibly adjust the mixing speed and set an appropriate mixing time based on the material characteristics and mixing requirements. Use an intelligent control system to monitor the mixing status of the material (such as temperature, humidity, mixing uniformity, and other parameters) in real time and automatically adjust the mixing speed, time, and paddle movement pattern.

3. Regular Maintenance and Calibration: Regularly check the wear of the paddle blades and replace any severely worn blades promptly to ensure optimal mixing performance. 4. Real-time Monitoring and Feedback: An online monitoring system monitors parameters such as temperature, humidity, and material flow rate within the mixing chamber in real time and feeds this data back to the control system. Based on this real-time monitoring data, mixing parameters are automatically adjusted to ensure uniformity and stability of the material mix.

These measures effectively improve the uniformity of raw material mixing in the organic fertilizer production line, ensuring product quality and production efficiency.
