The water jacket centrifuge is a gravity mineral processing equipment developed by our company. Practice has proven that it is extremely effective in selecting individual gold in vein gold mines and can replace mercury plates. It also provides a new type of gravity separation equipment to solve the problem of recovering individual gold in old tailings. In addition, it can also be used to recover single gold in gold ores and other metals.
Working principle of centrifugal concentrator:
This equipment is driven by an electric motor through a belt drive to drive the hollow shaft to rotate the inner sleeve at high speed. The slurry is fed into the inner lattice through the ore feeding pipe, and the light minerals are discharged through the tailings chute. After one shift of operation, the concentrate is discharged from the concentrate discharge port after the machine is shut down.
Operation of centrifugal concentrator equipment:
1. Preparation and inspection before start-up
(1) Prepare and inspect the motor before use according to the motor usage requirements.
(2) Check whether the equipment feet are stable.
(3) Check the tightness of the V-belt and adjust it appropriately (the test machine has been adjusted before leaving the factory).
(4) Check whether there is any interference with the moving parts of the equipment and perform manual turning inspection.
(5) Check whether the 10 concentrate discharge port is closed.
2. Start up of equipment
After following the above five preparatory inspections, turn on the power, jog the motor, and follow the direction of the arrow marked on the outer surface of the tailings chute of Equipment 7 to check that the running direction of the motor is consistent with the equipment requirements and that there is no interference between the moving parts before proceeding. The power can be turned on to put the equipment into normal operation.
3. Equipment water supply and mineral supply
After the equipment enters normal operation, open the backflush valve to supply water, and then feed the slurry configured according to the required liquid-to-solid ratio.
4. Things to note when working with the equipment
(1) According to the normal usage of the motor, monitor its temperature and current status.
(2) Pay attention to observe whether there are any abnormalities in the condition of various moving parts.
(3) Pay attention to the liquid-to-solid ratio of the slurry at any time and adjust it in time.
(4) At certain intervals, open the peephole on the upper cover and check whether there is any abnormality in the heavy sand deposition between the 5 inner sets of grids.
5. Equipment shutdown
In normal operation, this equipment cleans the concentrate once per shift, and the cleaning time is 15-20 minutes.
Before shutting down, first stop feeding the slurry, then stop feeding water, and then shut down the machine. After the equipment stops, unscrew the screw plug of the 10 concentrate discharge port and flush the concentrate into the self-prepared concentrate box. Finally, tighten the sealing plug of the 10 concentrate discharge port and proceed to the next cycle.
6. Equipment shutdown abnormally
In case of special circumstances, when a temporary shutdown is required, the ore feed must be stopped first, then the backflush water must be stopped, and then the machine must be shut down. If the machine needs to be shut down for a long time, the concentrate needs to be cleaned before inspection and maintenance to prevent heavy sand from hardening in the 5 inner sets of grids.
When starting the machine again after shutting down, be sure to provide backflush water first and then the slurry to avoid the loss of gold particles.
Nelson centrifugal concentrator equipment maintenance:
1. Carry out periodic maintenance according to the motor usage requirements.
2. The equipment is cleaned once every shift.
3. Adjust the transmission belt in time and tighten the positioning bolts. The machine must be stopped during adjustment.
