Air classifiers can be equipped with inert gas protection. This method is primarily used to prevent adverse reactions such as oxidation, corrosion, or combustion during the classification process. When handling materials that are prone to oxidation, flammability, or explosion. An inert gas-protected air classifier is a type of equipment that uses inert gases (such as nitrogen or argon) as the working medium to classify materials.
Gas Replacement and Circulation:
Before starting the classifier, the air inside the equipment is first replaced with an inert gas, creating an oxygen-free or low-oxygen environment. During the classification process, the inert gas is continuously circulated within the system to maintain an inert atmosphere, isolating the material from oxygen and preventing oxidation.
Material Classification:
The material is fed into the classifier through a feeding system, where it is subjected to high-speed airflow. Centrifugal force generated by the airflow separates particles of different sizes, achieving classification.
Real-Time Monitoring and Adjustment:
Oxygen content analyzers and other monitoring devices are used to ensure that the oxygen level remains within safe production standards.
Parameters such as the classifier wheel speed and airflow velocity can be adjusted based on material characteristics and production requirements to achieve precise control over particle size.
High Safety
Inert gas protection effectively isolates oxygen, preventing oxidation, corrosion, combustion, or explosion during classification. The equipment is equipped with explosion-proof devices, pressure relief systems, and anti-static specialized filter materials to further enhance operational safety.
Precise Particle Size Control
By adjusting the classifier’s parameters, precise control over particle size can be achieved to meet various production needs. High classification accuracy and sharp cut points help improve product quality and market competitiveness.
High Production Efficiency
The inert gas-protected air classifier operates in a fully enclosed, negative-pressure mode, reducing dust pollution and material loss. With a high degree of automation, the equipment supports one-button start/stop and remote control, reducing labor costs and operational intensity.
Wide Applicability
Inert gas-protected air classifiers are widely used in processing metal powders, oxidation-prone materials, flammable and explosive substances, as well as pharmaceutical ultra-fine powders. They are particularly suitable for products with strict particle size limitations and narrow distribution requirements, such as heavy calcium carbonate, kaolin, talc powder, and barite powder.
Environmental Friendliness and Energy Efficiency
The inert gas can be recycled, reducing resource waste and environmental pollution. The equipment operates with low noise and vibration levels, meeting environmental protection standards.
In summary, inert gas-protected air classifiers not only protect materials from oxidation, corrosion, and other harmful effects but also offer high safety, precise particle size control, high production efficiency, broad applicability, and environmental benefits. These advantages make this equipment widely adopted and highly recognized in industrial applications.
