A portable, in-line conveyor grounding system includes an electrically conductive metal pipe having a material flow section, with an inner diameter greater than that of an inlet and outlet, and a metallic grating disposed in the material flow section. An inlet attachment device and an outlet attachment device, as well as an electrically conductive wire with a grounding clamp, is provided. An electrically insulating wrapping is wrapped about the conductive wire and electrically conductive pipe, with a section of the wire having the grounding clamp exposed.
