Water dust suppression sprays, dust, build-up, large lump to fines ore size, grizzly beams etc.
Level Technology Choice
For this mining and minerals application, we always recommend a non-intrusive level technology that is positioned out of the way of being physically damaged by the truck and the falling Ore. If a Grizzly is installed, position between two beams in a central position of the ROM Bin is always the best. Two technologies are available; Radar and Acoustic level transmitters. Both have the range capability in a dry application, but when Water Sprays are used to suppress dust, the water and dust build-up on the Radar will make it fail. The best choice is to use a low frequency 10 kHz Acoustic transducer to provide a self-cleaning capability with each pulse as well as a polyurethane rubber focalizer cone to diminish breakage. These Acoustic Transmitters can be powered by 2-wire comms, loop power, or AC/DC supplies.
