Tow Distinc Features for NEFCO Centrifugal Concentrator

1. The rings are formed in a spiral in a continuous run they're not individual ringlets.
because it's running in a counterclockwise rotation while the water and bowl are spinning in clockwise. It keeps in a slurry state and that allows these black sands to wash out but the gold to remain trapped against the wall. (check the following picture)

Instead of an individual ring that will pack up the spiral allows the bowl to be run continuously all day long and at the end of the day, you will get one gallon of concentrate to clean up. Regardless if you've run five tons of materials.
2. Under the bottom of each one of these rifles, you can't see it, but there's a little cut around this edge bottom edge that prevents the fine gold from traveling and migrating up to the next riffle. In the next riffle which is common for centrifugal force to occur so the material comes in once it's in that ring it stays in that ring and it doesn't move up and out

2. How to operater the other kinds of centrifugal concentrator?

(1)The normal Centrifugal Concentrator Introduce

Hengchang Bowl 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. The 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 upcycle is 1~4 hours, and the upgrade ratio is up to 1,000 times. The equipment is patented in China.

(2) Operation of Bowl Concentrator

Before starting the preparation and check:
1. According to the instructions of the 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 the interference of moving parts, manual turning checks.
5. Check the discharge port (10) is closed.

-1.Start-Up of Bowl Concentrator

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.

-2. Equipment work note for Bowl Concentrator

1 monitor the stability and current by use of a conventional motor.
2 watch every moving part 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                                                   

-3. Stop of Bowl Concentrator

The equipment needs clean up concentrates per normal work shift. Before stopping, 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 the drain plug, the next cycle of operation.

If you meet the special conditions, 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 shut down.) 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.
