Air Classifier
An Air Classifier is a machine used in recycling facilities to separate different materials based on their weight using air streams. Think of it like a high-tech fan system that sorts lighter items (like paper or plastic) from heavier ones (like metals). This equipment is crucial in modern recycling plants to make the sorting process more efficient and accurate. Similar equipment includes density separators or wind sifters. These machines help recycling facilities process more materials faster and with better accuracy than manual sorting alone.

Example Interview Questions
Senior Level Questions
Q: How would you optimize an air classification system for different types of materials?
Expected Answer: A senior operator should explain how to adjust air flow, feed rates, and machine settings for different materials like paper, plastic, or metal, and discuss troubleshooting common separation issues.
Q: What safety protocols would you implement for air classifier operations?
Expected Answer: Should discuss equipment lockout procedures, dust management, personal protective equipment requirements, and regular safety checks and maintenance schedules.
Mid Level Questions
Q: How do you maintain air classifier equipment for optimal performance?
Expected Answer: Should describe regular cleaning procedures, checking for wear and tear, monitoring air flow systems, and preventive maintenance schedules.
Q: What factors affect separation efficiency in an air classifier?
Expected Answer: Should mention material moisture content, feed rate, air flow settings, and proper loading procedures as key factors in achieving good separation results.
Junior Level Questions
Q: What basic safety procedures do you follow when operating an air classifier?
Expected Answer: Should mention wearing proper safety gear, following start-up and shut-down procedures, and basic emergency response protocols.
Q: How do you know if the air classifier is working properly?
Expected Answer: Should describe basic indicators like proper material flow, normal operating sounds, and visual inspection of separated materials.
