The photos below show our Model 1800 froth flotation device with our other models. The 1800 model is about the size of a five
gallon bucket with a rubber membrane bubbler attached to the bottom. The membrane pulsates and expands upward
into the device (and creates bubbles within the fluid filling the tank) during operation to help present the settling of clay particles
during flotation. The photo below the top picture is a photo of the bottom of the model 1800 device when empty. The membrane
is shown expanded with a single pulse of air pressure. No extended pipes to break off or jam up, just a smooth rubber bottom
which pulsates to push sediment into the swirling and frothing flotation mixture during processing. Air under pressure flows
through the membrane to form bubbles and start the membrane pulsations when the tank is filled with water and sample
material. The bottom photo shows the 1800 model running with a battery powered compressor used for automotive tires.
After processing in the tank, the sample is poured through the stacked screens to the left of the tank.
