The " Earthquake " vibrating bucket classifier is extremely effective for screening both desert and river material. The classifier is built with a UV and water resistant coating. As your back well knows, the secret is to MOVE MATERIAL. The " Earthquake " will classify a 5 gal. bucket of dry or wet material in 3 to 5 minutes , and no stooping ...

A classifier sieve is a must have tool for rock hounding, gold and gem panning and proper classification of material to aid in fine gold recovery. Various screen / mesh sizes are available. Our classifiers are designed to work with all standard gold pan styles and most sizes fit on top of standard 5 gallon buckets.

Gold Classifiers. Gold classifiers, also called sieves or screens, go hand in hand with a gold pan. Designed to fit on the top of 5 gallon plastic buckets used by most prospectors, and over most gold pans, the classifier's job is to screen out larger rocks and debris before you pan the material. Classifiers come in a variety of mesh sizes.

May 15, 2016· The 1/4 classifier is a good basic size if you just want one, but for optimal gold recovery its a good ideal to get several different screen sizes. Buying a set will allow you to sift down to extra fine material so that when you finally get to the gold panning process it will be a breeze.
Estimated Reading Time: 3 minsLive Chatparticle that passes a 150 mesh screen but is retained on a 200 mesh screen would actually have a diameter between 74 microns and 105 microns. For this paper, the size of 74 microns would be used for particles in this size range. Figure 3 also shows that the actual recovery curve does not decrease below a certain level.
