As the rakes are turned by the drive shaft they cause the concentrate that has settled onto the bottom of the thickener to be pulled into the discharge chamber at the centre of the thickener. This is called the CONE. It is from this cone that the thickener underflow is taken. During normal operations of the circuit, the thickener may be pulled ...

With a hard hat they tend to enter the cone upside down. This means that they will seal the only place that the thickener can be emptied from. The alternative is to empty the thickener with a pump which is a long slow job. As you can imagine, a hard-hat or tool or large rock would easily plug the thickener underflow and piping shown below.
