To remove static from a conveyor in heavy industries such as mining, employ antistatic rollers or grounding brushes. Antistatic rollers are designed to dissipate electrical charges as they rotate. Grounding brushes are placed in contact with the rollers or the belt, effectively grounding any static buildup. Installing ionizing bars or blowers can also neutralize static charges. Regularly cleaning the conveyor and maintaining proper humidity levels in the working environment can further reduce static accumulation. Ensuring that all components are properly grounded is crucial for preventing static-related issues that could disrupt operations or pose safety hazards.
