The wet pan mill is named by the diameter of roller. Φ1300,Φ 1350,Φ 1400,Φ 1500,Φ 1600 is suitable for selection of iron ore, molybdenum ore ,lead ore ,zinc ore, antimony ore and so on. Φ 850, Φ 900, Φ 1000,Φ 1100,Φ 1200 is suitable for selection of gold ore. Above all, 1200a type is the most popular and widely use.
 
2 : Working Principle of wet pan mill  
The Wet pan mill repeatedly squeeze and mill gold ore through the weight of the wheels until the gold ore has been crushed completely. And then add 1 kg mercury into the water .
