Common problems and solutions in flotation process


1.Flotation machine Poor flotation effect, high tail loss

This situation may be the flotation machine material grinding fineness is not up to standard or flotation agent dosage problem.If the grinding fineness cannot reach the indicators, the grinding fineness should be appropriately increased, and the grinding section number can be increased.

If the dosage of flotation reagents occurs, the flotation reagents should be tested to determine the dosage and indicators of flotation reagents.

2.Flotation machine flotation cell foam larger, surface reflective

When the floatation cell appears larger foam, and the surface appears reflective phenomenon, the possible reason is the flotation agent added too much, at this time the operator should adjust the dosage of flotation agent, observe whether the flotation foam condition has improved.

3.The liquid level of the single flotation cell of the flotation machine is on the high side

If the problem of high liquid level in a single flotation cell appears in the flotation machine, the reason is mostly the clogging phenomenon of the suction pipe. At this time, the operator needs to stop the operation to clean the suction pipe.

4.The scraper blows out the foam with a lot of ore pulp, the foam layer is thin and fragile

There are four possible reasons for this situation, one is the overflow concentration is too thin, two is the position of the liquid level adjustment board is too high, three is the slurry overflow concentration is too thick, this situation will also lead to run coarse and serious sand deposition, four is the inhibitor and adjustment agent dosage is too large, resulting in the failure to produce an appropriate amount of foam.In this case, the operator should first observe the situation, control the pulp concentration and fineness, and pay attention to control the dosage of regulator and inhibitor.

5.Floatation machine Flower-over phenomenon of local liquid level

Floatation Flower-over phenomenon in the tank liquid surface of the flotation machine shows that the slurry foam layer is not stable, it is possible that the cover plate is installed uneven, resulting in uneven clearance, one side is large and the other side is small, the large clearance will produce the phenomenon of flapping. It is also possible that the loss of the stator results in uneven flow of the slurry at the bottom.A final possibility is a loose pipe joint.These three cases are caused by the flotation machine failure, The operator needs to inform the maintenance in time.

6.The flotation machine slurry level falls

In the working process of flotation machine, the ore slurry surface appears falling, which may be caused by too coarse grinding fineness, increased processing capacity, or insufficient dosage of medicament.The operator can solve this problem by adjusting the grinding grade, reducing the feeding capacity, or adjusting the dosage appropriately.

7.Flotation machine overswelling, foam chute ore more and more accumulation

Generally speaking, this situation has the following several reasons: floatation machine to feed too much, too much air, the middle box and liquid level adjustment board is blocked, suction tank suction capacity is insufficient, washing water pressure is too small.In these cases, the liquid level adjustment plate jam is the most likely to cause grit, should minimize level adjustment plate, dredge clogs, necessary to open the bottom valve, make the slurry flow and check whether your and acid pipe blocked, at the same time should be proven to ore and overflow concentration, timely find out the reason, and timely adjust to ore according to reason or other factors.

8.There is no pulp in the dc tank at the tail end of the flotation machine,Scraper slurry serious, overflow fineness run coarse

When this phenomenon occurs, the operator should first stop mining, and then open the bottom bottom flow valve of the flotation machine trough, and then feed the ore and block the bottom flow valve after the pulp flow returns to normal, and pay attention to control the consistency of the pulp at the same time.

The above eight problems are common abnormal phenomena and solutions in the flotation process of the flotation machine. I hope they can be helpful to the mine owners.

Operation of Jaw Crusher

图片
Operation Instructions of Jaw Crusher 1.The preparation before starting: (1) Inspect each bearing to ensure whether it lubricates well, and whether there is enough lubricating grease on the toggle plate joints and bearing inners. (2) Check carefully whether all fasteners are totally fastened. (3) Check whether the drive belt is under good condition, and change the belt if any damages can be found. When there is grease contamination on the belt or bell wheel, it can be clean up with a clean dishcloth. (4) Check whether the protective device is under good condition, if there are any unusual events and safety hazards conditions, should correct them and report. (5) Check whether there are any ore or other impurities inside the crushing cavity. 2.The starting of the crusher (1) After inspecting the machine and transmission parts are under good condition, the machine may starts. (2) This machine can only start under empty load conditions. (3) After having started the machine, shut down the

What factors affect the output of cone crusher

图片
What factors affect the output of cone crusher There are three main factors influencing the productivity of cone crusher : the number of times of the swing of the cone;The length of the parallel crushing area;The size of the engagement Angle.These three aspects directly determine the output of cone crusher. 1.the number of times of the swing of the cone The swing times of the crushed cone is one of the key factors affecting the crusher productivity. Because of the limitation of the meshing Angle of the crushing cavity and the parallel ore discharge area, the crushed ore is discharged along the taper inclined plane mainly by gravity and vibration.When the number of spindle rotation increases, the ore is easy to be discharged, but the number of rotation is too high, which is not conducive to ore discharge, sometimes resulting in faster speed and unable to produce.Therefore, the number of swing of the broken wall has a certain constraint on the improvement of productivity. 2.The l
