An aggregate conveyor metal detector is a device used in the mining and aggregate industries to detect the presence of metal contaminants in the material being conveyed on a conveyor belt. This type of metal detector is essential for preventing damage to processing equipment, such as crushers, and ensuring the quality of the final product.
Here's how an aggregate conveyor metal detector typically works:
The metal detector is installed on the conveyor system, usually just before the material reaches a critical processing point, such as a crusher or a screening machine.
2. Detection Technology:
Various technologies can be used for metal detection, including electromagnetic coils, pulse induction, and others. The choice of technology depends on factors like the type of material being conveyed and the size of metal contaminants you want to detect.
3. Sensitivity Settings:
The metal detector can be calibrated or set to specific sensitivity levels based on the size and type of metal contaminants you want to detect. This ensures that it can identify both large and small metal pieces.
4. Alarm System:
When metal contaminants are detected, the metal detector triggers an alarm. The alarm can be visual, auditory, or both. This alerts operators to the presence of metal in the material being conveyed.
5. Material Diversion or Stopping:
In some systems, upon metal detection, the conveyor system can be programmed to stop automatically or divert the contaminated material to a separate area for further inspection or removal of the metal.
6. Integration with Control Systems:
The metal detector is often integrated into the overall control system of the processing plant. This integration allows for seamless coordination between the conveyor system, metal detector, and other processing equipment.
Benefits of using aggregate conveyor metal detectors include:
1. Preventing damage to downstream equipment like crushers and screens.
2. Ensuring product quality by removing metal contaminants.
3. Reducing downtime and maintenance costs.
