1. Raw Material Characteristics Matching
Material Type: Powder, granules, fibers, or liquid impregnation, etc. Different materials have different requirements for fluidization, heating, or spraying methods.
Heat Sensitivity: For heat-sensitive raw materials (such as biological agents), low-temperature fluidization or adjustable airflow models should be selected to prevent thermal degradation.
Adhesion and Flowability: Highly viscous powders should be selected using fluidized beds with adjustable airflow or pellet mills with anti-sticking devices.
Referring to the selection recommendations for fluidized bed pellet mills, material characteristics are the primary consideration.
2. Production Capacity Requirements
Daily/Hourly Output: Determine the maximum required production capacity (kg/h) based on the production plan.
Continuous Operating Time: Equipment operating for extended periods requires excellent heat dissipation and a reliable bearing design.
3. Particle Size and Distribution
Target Particle Size: Determine the median particle size (D50) and particle size distribution range based on the final product's usage requirements.
Adjustment Method: Consider whether replaceable screens, adjustable cutters, or spray angles are needed for flexible particle size adjustment.
4. Power and Energy Consumption
Motor Power: Directly related to production capacity, material viscosity, and processing method. Excessive power wastes energy, while insufficient power affects output and
particle size uniformity.
Energy Efficiency Index: Focus on the electrical energy consumed per kilogram of output (kWh/kg). Selecting a low-energy-consumption model helps reduce operating costs.
5. Feeding and Conveying System
Feeding Method: Screw feed, vibrating feed, or pneumatic conveying. Must be matched to the flow characteristics of the raw material.
Conveying Path: Require a matching cooling conveyor belt, screw conveyor, or pneumatic conveying system to ensure rapid cooling of the particles after forming and their transport to the post-processing unit.
6. Temperature, Humidity, and Environmental Control
Heating/Cooling Method: Electric heating, steam heating, or water cooling. This is especially critical for heat-sensitive or drying materials.
Operating Temperature Range: The equipment's upper temperature limit should exceed the maximum process temperature, and it should have uniform temperature control.
7. Automation and Control System
PLC and Touch Screen: Enables real-time monitoring, parameter setting, and alarm linkage.
Sensor Configuration: Includes online sensors for temperature, pressure, flow rate, and particle size detection, improving product consistency and reducing manual intervention.
8. Post-Processing Compatibility
Screening/Grading: Whether equipped with a vibrating screen or air classifier for automatic separation of qualified particles.
Packaging/Storage: The pellet mill's discharge method should be compatible with subsequent packaging or silo systems to avoid secondary blockages.
9. Supplier Qualifications and Service
