"CONCRETE MIXERS" Lightning Ridge Warnings Or Dangers Tip by balhannah

Concrete mixers I hear you say! What can a tip be about a Concrete Mixer?

At the entrance of the road that takes you into the Town of Lightning Ridge, we saw our 1st Concrete Mixer Agitator. We had no idea why it was there, until we did a tour later on.

The Agitators are the modern way of separating the clay from the Opal. The opal clay is fed into an agitator, which can be described as a modified concrete mixer, this serves the function of separating the clay from the opal, by washing it.

It’s a hard, dry landscape of shafts, with Cement mixers churning over opal dirt mixed with artesian bore water.
