Huahong high recovery rate Gold machine

Hengchang gold machine/ STLB Water- jacketed 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.

Equipment operation

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.

Equipment 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 equipment:

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:

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 (5) resend between cell deposition tank, with or without exception.

Equipment stop:

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.

Equipment abnormal shutdown:

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, then shutdown.) In addition, when you open again after temporary shutdown, need feed slurry first, and then give backwash water, to avoid the loss of gold particles.

Equipment maintenance:

1. periodic maintenance according to the motor use requirement.
2. the equipment need cleaning per shift.
3. equipment must be shutdown if you need to adjust the drive belt or tighten loose bolts.

Construction and working principles of gold machine:

PRINCIPLE:

Motor (2) drive inner tank(5) rolling at high speed by belt(1) and axis(11). Separation work will be strengthened in the tank (5) by centrifugal force. Light material will be discharged by port (7), and final refined ore will be output by port (7) after stopping work.
