Wet pan mill or round mill is widely used for selecting ferrous metals, nonferrous metals and nonmetals, as well as precious metals like gold and silver. It mainly consists of driving device, frame, water basin, grinding wheels and grinding base, etc. It grinds ores by wheel driving force: firstly, the power is transferred from the motor to the reducer, then to the horizontal shaft, and finally to the grinding wheel; the wheels then rotate anticlockwise. The wheels can revolve around the vertical shaft of the pan mill, at the same time, it can revolve on its own axis, while the grinding base will remain still. The ores are then pressed, rubbed and grinded repeatedly. 
Features of wet pan mill:
1. Uniform grinding, high quality finished product The roller is combined with the mixing and slurrying function while rolling and smashing minerals. The material and water are thoroughly mixed uniformly to stabilize the grinding indexes such as the slurry concentration. The finished product has high density, good strength and no porosity. 2. Make full use of resources, energy efficient In the iron ore process, the tailings are recovered by a wet mill without losing the ore powder. Make efficient use of resources, energy efficient, and high output. 3. Stable operation and reliable quality The wet mill has a simple structure and is easy to operate. The grading granularity can be strictly controlled to avoid the phenomenon that the mineral is excessively pulverized or the grain size is uneven, and the quality is guaranteed.
1) The grinding wheels mix up the ores and produce ore pulp while pressing and rubbing the ores.
2) The ores and water are evenly mixed, which makes the pulp density and other indexes stable.
3) After the grinding process, the monomers are taken to the upper surface of the pulp and discharged through the overflow outlet of the water basin. Meanwhile, the coarse ores sink to the bottom of grinding base, being grinded continuously till they reach the required fineness.
4) The screening mesh set up at the overflow outlet of the water basin classifies the ore fineness strictly to avoid the over-grinding and uneven fineness, which helps create better condition for next working process.
Working principle of wet pan mill:
It mainly consists of driving device, frame, water basin, grinding wheels and grinding base, etc.
1) When inputting gold sand into the rolling drum, the rollers compress the sand over and over into tiny particles.
2) Please put in 5 kg mercury at first, the mercury can absorb the gold or other metals.
3) At last, use a high-density red cloth to wrap mercury up.
4) Then squeeze it, the mercury will be pressed out and pure gold stayed.
5) As to the large capacity, we can use mercury shaking machine and mercury steamer to replace the manual work.
