Hengchang STLB gold centrifugal concentrator is a kind of centrifugal concentration 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.

Operation of gold centrifugal concentrator:
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 is closed.

Gold centrifugal concentrator start-up:
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.

The mine and water supply for the gold centrifugal concentrator:
When the equipment into the normal operation, the recoil valve open, at the same time, feed the required liquid-solid ratio slurry.

Equipment work note for gold centrifugal concentrator:
1. Monitor the stability and current by use of conventional motor.
2. Watch every moving part without exception condition.
3. Pay attentions 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 resend between cell deposition tank, with or without exception.

Stop the gold centrifugal 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 is 15 to 20 minutes. Then, tighten drain plug, the next cycle of operation.
