The core of optimizing production with half-wet material crushers is to solve clogging problems, improve crushing efficiency, and reduce energy consumption. This is achieved by focusing on three key dimensions: material pretreatment, equipment parameter matching, and wear part management, while balancing stability and increased production capacity.
1. Material Pretreatment: Reduce clogging and wear from the source. Control moisture content; the optimal moisture content for semi-wet materials is 5%-15% (common organic fertilizer materials such as livestock manure and straw). Excessive moisture easily causes clogging of the screen, while too little moisture results in excessive dust and high energy consumption. This can be addressed through drying/air-drying pretreatment or fine-tuning with a humidifier.
2. Material Cleaning: Remove stones, metal, and other hard objects from the material beforehand to prevent wear on the blades and damage to bearings, reducing the frequency of downtime and maintenance of bio organic fertilizer equipment.
3. Speed Adjustment: Adjust the main shaft speed using a variable frequency motor. For soft materials (such as composted manure), the speed can be appropriately reduced to decrease dust and energy consumption; for hard materials (such as straw and oilseed cake), the speed needs to be increased to ensure the required fineness of crushing.
4. Screen Selection: Change the screen mesh size according to the finished product requirements (1-3mm is commonly used for organic fertilizers), avoiding "overkill" (e.g., using a fine screen when a coarse product is sufficient, increasing the equipment load); also, regularly clean screen blockages, and consider adding a vibration device to assist in material discharge.
5. Wear Part Management: Blades, hammers, and screens are core wear parts; high-wear-resistant materials (such as high-manganese steel and alloy materials) should be used.
6. Lubrication and Maintenance: Regularly lubricate bearings, main shafts, and other moving parts with high-temperature, wear-resistant lubricating oil (recommended every 8-12 hours) to prevent dry friction and resulting downtime.
