What type of conveyor can be powered or unpowered?

Chain conveyor
Magnetic conveyor
Roller conveyor
Belt conveyor

The correct answer is: Roller conveyor

The roller conveyor is designed to operate in both powered and unpowered configurations, making it a versatile option in material handling. When powered, the rollers are driven by a motor, allowing for efficient movement of items along the conveyor system. This setup is often used in automated systems where products are transported from one area to another with a consistent speed. On the other hand, an unpowered roller conveyor relies on gravity or manual effort to move items. This type is commonly found in applications where materials are loaded onto an incline, allowing for downward movement through sloped sections. This dual functionality provides flexibility in design and usage, enabling millwrights to select the most appropriate system based on operational requirements and resources available.
