Wet pan mill is a popular gold and silver ore grinding machine in Africa and South America countries, because of its low investment, easy use and maintenance, and quick cost recovery. The most common way is to put mercury in the wet pan mill, and mix the gold particle with the mercury, which is called Amalgamation.
· In roller mills, the principle of attrition is used where material is sheared as it passes through a gap and is transferred from slower roll to a faster roll, and is removed by a scraper. In ball mill, size reduction is done by both impact and attrition of particles. Rod mill is similar to ball mills but it uses long rods for grinding media. Autogenous mill is a selfgrinding mill which is ...
