The Pro-Camel 18 Automatic Gold Panning Machine (18″ Spiral Wheel) is essentially the same machine as the Pro-Camel 24 but with a different size wheel. Even a seasoned gold panner is going to miss some gold when panning by hand, especially if the concentrates are heavy with black sand.
A semi-empirical mathematical model for a spiral classifier is proposed in this paper. The model is based on the observations of the movement of particles within the trough of a spiral and makes use of several hypotheses that still need to be validated with dedicated experiments. The objective of the model development was to allow the ...
