■ Product Overview
The Gravity Fall Metal Detector is a highly sensitive metal foreign object detection device specifically designed for freely falling bulk materials.Vertical Metal Detector is widely used for online detection of granular, powdered, and small block products. The material falls naturally through the detection coil under gravity. Once impurities such as ferrous, stainless steel, or non-ferrous metals are detected, the system immediately triggers a high-speed rejection device, achieving automatic waste removal without stopping the machine and ensuring product safety and production continuity.

■ Main Features
1. High Sensitivity Detection
Utilizing digital DSP signal processing technology, it can stably identify Fe/SUS/Non-Fe metallic foreign objects, maintaining excellent detection performance even in powders and small particles.
2. Gravity Fall Structure Design
No conveyor belt; material naturally passes through the detection channel, reducing product accumulation and residue, suitable for free-flowing materials.
3. High-Speed Automatic Rejection System
Pneumatic flap or baffle-type waste removal structure, fast response, low false rejection rate, and no impact on normal production cycle.
4. Modular Hygienic Structure
Food-grade stainless steel body, quick-release channel design, convenient cleaning and maintenance, meeting the requirements of food-grade production environments.
5. Easy-to-integrate control interface: Supports linkage with packaging machines, checkweighers, and PLC systems to achieve intelligent control of the entire production line.
