1-100tph Alluvial gold refining equipment / STL30/STL60/STL80/STL100 gold centrifuge separator concentrator Faclon/Knelson/Nelson/Neffco
Centrifugal Concentrator is a kind of gold gravity equipment. It can be used not only for placer gold mining, but also for hard rock mining to recover the natural gold, replacing amalgamation. It is also used to recover gold from the old tailings.
Five models are available. Application shows that the recovery can be as high as 90%, especially for the case in recovering the natural gold in lode ore with 65% of the ore having a milling size of 0. 074mm, the recovery for the natural gold is expected up to 98%, For that natural gold of 0.004mm in particle size, the recovery is 97%. The cleaning up cycle is 1~4 hours, and the upgrade ratio is up to 1,000 times. The equipment is patented in China.
Application Fields
1. Recovery of Gold from Alluvial or hard rock deposits
2. Upgrading and recovery of gold from concentrates from other gravity separation stages eg jigs, spirals and cone concentrators
3. Used for exploration and evaluation of gold deposits as well as small production
4. Other mineral applications include niobium, tantalum, coltan, tin, tungsten, and scheelite
Working Principle
Motor drive inner rubber bowl rolling at high speed by belt and axis. Separation work will be strengthened in the rubber bowl by centrifugal force. Light material will be discharged with the water, and final refined gold ore will come out from the outlet after stopping work.
1. Batch operation with simple cleaning to remove concentrate
2. Relatively low rotational speed to minimize maintenance requirements
3. No added water for bed dilation
4. Simple construction
5. Low capital cost
6. Compact and lightweight
7. Bowl geometry designed for maximum gold retention
Operation of Gold Centrifugal Concnetrator
Before starting the preparation and check:
1. According to the instructions of motor required for the preparation and check before use.
2. Check the equipment whether the anchor is stable.
3. Check the state of V-belt tension and adjust appropriately (factory test machine has made adjustments)
4. Check the equipment without interference of moving parts, manual turning checks.
5. Check the discharge port (10) is closed.
Start-Up of Centrifugal Concnetrator
After the above five ready to check , turn the power to start the motor, check motor rotation direction and equipment requirements are the same, whether the interference of moving parts, and then turn on the power, make the equipment into normal operation.
Equipment work Note
1 monitor the stability and current by use of conventional motor.
2 watch every moving parts without exception condition,.
3 pay attention to slurry ratio, try to adjust it in time.
4 intervals for a period of time, open the peephole on the cover, observation of inner sleeve
Stop of Mineral Processing Concentrator
The equipment need clean up concentrates per normal work shift. Before stop, first stop feed mine, then stop the equipment, wait for equipment is stationary, unscrew the drain plug concentrate outlet , the ore concentrate into the ore tank (prepared in advance) can be. Cleaning concentrate time to 15 to 20 minutes. Then, tighten drain plug, the next cycle of operation.
If meet special condition, need to temporary shutdown, must first stop to feed mine, then stop backwash water, and then go down.But the downtime should not be too long, too long to prevent resolve within the set of grid sand compaction. (if required downtime long, you need to clean the concentrate first, hen shutdown.) In addition, when you open again after temporary shutdown, need feed slurry first, and then give backwash water, to void the loss of gold particles.
