Size #1 Jobe Stainless Steel Classifier
 

These quality stainless steel classifiers have rugged plastic bodies with stainless steel screens. They are 12 inches (~30cm) wide at the top and are tapered to fit in the top of a 5 gallon bucket. They are easy to use and a must for proper fine gold recovery. 

 
The overall height is 3 1/2 inches (~9cm) and designed to allow for 4 of the classifiers to be nested with an overall height of only 8 1/4 inches (~21cm)as shown in the photograph.
 
IMPORTANT NOTE:  this item is for one (1 only) classifier of 1/2" - adjust quantity if you need more than one.
 

Classifier Screen (mesh) sizes (click here for mesh size comparison photo gallery):
  • #1  - 1/2 inch (the largest screen) is about 4 holes per square inch (use to remove worthless larger rocks) 
  • #2  - 1/4 inch is about 16 holes per square inch (use to reduce size of gravel material for easier sluicing or panning) 
  • #3  -  1/8 inch is about 64 holes per square inch (use for final clean up of gold concentrates from black sand or for recovery of small gem stones) 
  • #4  -  1/12 inch mesh - good all around size.

  • #6  -  1/30 inch  - SUPER FINE MESH - a very tight weave 
  • #7  -  1/50 inch - VERY FINE MESH - 2500 holes per square inch- OFTEN USED WITH #30 and #70 screen for BLUE BOWL CLEANUP 
  • #8  -  1/70 inch - VERY FINE MESH - 4900 holes per square inch - use with the #6 (1/30") and #7 (1/50") screens for best blue bowl recovery.
