Air classifier mill is a high-efficienct powder grinding equipment that integrates grinding and classifying. Its core working principle is to grind and classify material through high-speed rotating grinding rotor and classifying wheel.
Although air classifier mill is easy to operate, we still need to pay attention to the following precautions to ensure efficient operation of the equipment and extend its service life.
Precautions for using air classifier mill
1. Equipment installation
Solid foundation: we should install air classifier mill on a solid foundation to avoid damage to the equipment or impact on grinding due to vibration.
Good ventilation environment: Good ventilation is necessary, ’cause it can avoid dust accumulation and ensure a safe operating environment.
2. Material selection
Material hardness: Air classifier mill is suitable for materials with medium hardness or below. Materials that are too hard may cause accelerate equipment wear and even damage the rotor or classifying wheel.
Material humidity: Excessive material humidity may cause blockage or adhesion in grinding chamber, affecting the grinding effect. For material with high humidity (usually the humidity should be within 2%), it is better to dry it first.
3. Operation parameters
Feeding speed: The feeding speed should be uniform. Too fast may cause equipment overload, while too slow may affect production efficiency. The feeding speed should be reasonably adjusted according to the properties of the material and the processing capacity of the equipment.
Classifying wheel speed: The speed of classifying wheel directly affects the particle size distribution of the material. The higher the speed, the finer the classification fineness, and the lower the speed, the coarser the classification fineness. The speed of classifying wheel should be reasonably adjusted according to product requirements.
Air volume and air pressure: The adjustment of air volume and air pressure has an important influence on grinding efficiency and classification accuracy. Excessive air volume may result in the inability to effectively collect fine particles, while insufficient air volume may cause accumulation of the material in grinding chamber.
4. Equipment maintenance
Regular inspection: Regularly check the wear of key components, such as: the rotor, classifying wheel, and the fan, and replace severely worn components in time to ensure the normal operation of air classifier mill.
Lubrication and maintenance: Regularly lubricate bearings, gears and other moving parts to reduce friction loss and extend the service life of the equipment.
Clean up accumulated materials: Regularly clean up accumulated materials in grinding chamber and grading area to prevent materials from clogging or sticking and affecting the grinding effect.
5. Safe Operation
Protective equipment: Operators should wear protective glasses, masks，etc. to avoid dust inhalation or injury from splashes.
Emergency shutdown: If abnormal noise, vibration or overheating occur during the operation, stop the equipment immediately for inspection.
6. Environmental requirements
Dust control: Air classifier mill will generate a lot of dust during operation, so it should equip with effective dust removal equipment, such as bag filter, to ensure that dust emissions meet environmental protection requirements.
Noise control: In order to prevent the noise generated during equipment operation from harming the operators, sound insulation measures should be taken, or the operators should equip with protective equipment, such as earplugs.
Conclusion
Through reasonable operation and maintenance, air classifier mill can provide enterprises with efficient and stable powder processing solutions, extend the service life of the equipment, and ensure production safety and environmental compliance.
