HSM CE CIQ Wet-mill Concentration

1:wet-mill concentration Product Description

wet-mill concentration 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

2:Advantages of wet-mill concentration

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.

3:Features of wet-mill concentration:
1 wet-mill concentration after the installation is completed to gold grinding machine groove bottom 5 kilograms of mercury begins normal operation.
2 each class receive once the Sands, the shift added to 1 kg of mercury to receive the grind at the end of the Sands and mercury, the mercury received  gold equipment, with a relatively high density of red cloth mercury screwed out to the package, open the red cloth which left Sands. One kilogram of mercury each class started on it. Containing one is grasping the cloth of gold or grab the gold behind the blanket and put on the mercury board can receive the gold.

4:Working Principles of wet-mill concentration:
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.
 
5:wet-mill concentration Use and Maintenance: 
1.The normal operation of the mill, before they start feeding.
2, this machine prohibit strip start, the outage at boot time, you must first clean up the residual ore in the middle of the milled slot and then start.
3, should be uniform feeding not erratic, it is best to use the feeder.
4, bearing frequent butter, gear box or car rear axle with frequent checks whether the loss of gear oil.
5, regular checks of the various parts of the screw is loose.
6.Found bearing damage must be promptly replaced, shaft eccentric avoid damage to other parts
7 mill runtime to pay attention to that the reducer or bearing part of the presence or absence of abnormal sound, whether the temperature is too high, the motor current is too large irregularities; should be shut down immediately if the above phenomenon, exclude.
