I need at least 4 control stages in the flotation cell train to provide circuit flexibility A control stage is defined as a cell or cells which operate with a common level control.Many people use the term cell bank to define this group of cells.Each control stage can be considered a unit reactor from which a tail and concentrate can be .
A float switch regulates the water level and turns off the main pump when reaching a certain point of overflow.Likewise, it also moderates low water levels by ensuring the reservoir never runs dry.Building your own float switch requires a simple setup consisting of several drill holes, mounting screws and cheap, reliable parts.
A higher float height will allow more fuel into the mixture, creating a richer mixture.Now you see why setting the float height is so important.If the float is off, then it’s going to be more difficult to jet all of the circuits.
Active-high circuit: Both inputs are normally tied to ground (LOW), and the latch is triggered by a momentary HIGH signal on either of the inputs.Active-low circuit: Both inputs are normally HIGH, and the latch is triggered by a momentary LOW signal on either input.These two projects show you how to build simple active-high and active-low latch circuits using a 4001 quad 2-input NOR gate .
