Jig machine beneficiation has the advantages of good separation effect, large processing capacity, wide range of sorting particle size, low investment, low production cost and simple process system, so it is widely used in the gravitational separation and beneficiation process.
Jig machine as an important equipment in the process of gravity separation, its operation is directly related to the quality of the product and the economic benefits of the concentrator, when the jig has abnormal problems may affect the normal operation of the process after that, to deal with it in time. Therefore, it is important to understand the common problems of jig machine and how to deal with them.The following is an introduction to the causes and solutions of several common problems of jig machine.
1.The Sieve Plate Of The Jig Machineis Loose or Cracked
During operation, if you find that the sieve plate beats with the pulsating water flow, it means that the screws of the sieve plate are loose or have fallen. If a certain part of the bed is found to be in a certain part of the bed during the rising period of water flow, the liquid level gushes out like a spring; During the period of water decline, the water flow falls very quickly, and at the same time, the material in the hoist body increases significantly, indicating that the sieve plate has cracked into a hole.
Solution: If the screws of the sieve plate are loose or falling, stop the machine immediately to clean the bed and tighten the screws; If the sieve plate is broken, it is necessary to stop the machine to drain the water, clean the bed, and repair the leakage of the sieve plate.
2.The Bed Of The jig machine is Emptied
The thickness of the bed is related to the properties of the material being processed (density and particle size), and in normal production, the bed must maintain a certain thickness and make it stable. However, sometimes due to the large opening of the gate or the improper adjustment of the automatic discharge device such as the electrode of the pressure test, the discharge is too much, resulting in the phenomenon of bed emptying.
Solution: When the bed emptying phenomenon occurs, it should be dealt with in time. Adjust the gate opening and electrodes to the appropriate position, and readjust the bed layer to make the bed thickness appropriate.
3.There Is A Problem With The Jig Machine Discharge System
In the discharging process, the supporting bending plate of the discharging system of the jigging machine is dislocated, so that the gap between the supporting bending plate and the lifting wheel is uneven, and the narrow part is rubbed, and the material overflows in the part with a large gap, so that the unsorted material enters the product. This is caused by the displacement of the lift wheel in the lift lane or the deformation or loosening of the support plate.
Solution: Adjust the lifting wheel support device and the guide wheel position in time during daily maintenance, and maintain the normal working position of the lifting wheel in the wheel path; Tighten the connecting bolts of the support bending plate in time and correct the deformed support bending plate.
4.Jig Machine Solenoid Valve Failure
When the solenoid valve of the jig is blocked, the sealing ring is leaking, etc., it is mostly caused by the failure of the air filter, the high-pressure air with water or impurities, and the failure to clean the solenoid valve during inspection. When the coil is broken or the wiring contact is poor, it will also cause the solenoid valve to be energized without a suctioning sound.
Solution: Clean the solenoid valve regularly, replace the sealing ring and coil, and replace the air filter.
The above is the common problems and solutions in the work process of the jig machine, special attention should be paid to the fact that there are many reasons for the failure, when the jig machine has a problem, the operator should analyze the specific problem. At the same time, it is recommended that all mine owners find equipment manufacturers with the overall qualification of the concentrator to purchase and maintain jigs to avoid the impact on the overall operation of the concentrator due to mechanical failure.
