Cascade Highbankers are designed to use classification from the beginning to the end! With most other mini high bankers, there is just an upper grizzly and then the screened rocks drop into a plain old sluice box. However, the Cascade is better in that it offers 3-stage classification!
First stage begins in the top feed area where fine gold immediately drops through a punch plate and into a removable fine gold collection tray. This tray is mounted underneath the top feed area. The removable tray is lined with rubber matting that classifies your gold and holds it in place. The tray can be removed without ever having to shut down. Just remove and rinse the contents into a clean pan.
Material that doesn't fall into the fine gold collection tray then continues to the second stage clafficiation which is the expanded metal grizzly. At this stage, large waste rock falls off the end, the rest of the material falls through the grizzly onto the sluice below. Cascade Highbankers feature expanded metal the whole length of the sluice box. The riffles are a solid one piece aluminum cut riffle that is mounted on hinges and two draw clamps that keep the riffles in the sluice. This ensures that your riffles will never get ruined by taking them out of the machine. The carpet underneath the riffles and expanded metal can be easily removed and cleaned and replaced. It is a rubber backed carpet that will last for many uses.
