Miners' moss and the turbulent water flow

Miners are using this type of a setup with two sluices after the hammer crusher. That is for the reason that the crusher cannot easily be stopped and started again, so they close one of the outputs to clean the carpet on one side while the other one is still running.

Miners' moss is incorrectly set, the water flow is turbulent, and expanded metal is missing to push the gold particles quickly down into the carpets.

A simple test have revealed that a lot of gold is being lost, just as much as one would want to find in the tailings.
