Gold Mining Gravity Separator-Jigger Machine

Sawtooth wave jig machine cover an small area, simple and convenient operation, is a new development in recent years the production of a highly efficient, energy-saving and environmentally friendly processing equipment, for a variety of metal and non-metallic mineral processing has a good effect, especially suitable for fine grained level of mineral dressing, recycling and mine tailings in metal smelting slag processing field played an extremely important.

The Working Principle 

The sawtooth wave rises in a straight line, then falls steeply, then rises again, then falls steeply, and so on. The traditional jig is mostly driven by circumferential eccentricity, and its jig pulsation curve is sinusoidal. The rising and falling water velocity and action time generated by diaphragm movement are basically the same. The pulsation curve of Lisault Du Jig shows a sawtooth waveform: The ascending water flow is faster than the descending water flow, the ascending time is short, the descending time is long, the looseness of the bed is enhanced, the absorption effect is alleviated, the heavy ore particles in the mineral are fully settled, and the sorting ability and recovery rate of the equipment are greatly improved. 

The selected material is drawn on the bed, and the bed stone and water form the grain group system. When the water impinges upward, the grain population is in loose suspension state, and then the light, heavy, large and small grains have different settling velocities. Dense coarse particles settle in the lower layer. When the water flow drops, the suction effect occurs, and the phenomenon of “separation” appears, that is, the ore particles with high density and small size pass through the gap of coarse particles into the lower layer. Because the diaphragm moves up and down for many cycles, the grain group system is stratified according to the density, thus playing the role of jig sorting.

Characteristics

1, compact structure, small footprint, large processing capacity per unit area. Jt1070/2 JIG adopts down-moving transmission structure, which makes the JIG equipment more compact and has larger processing capacity per unit area. 

2, the use of CAM mechanism transmission, the sawtooth waveform pulsation curve to make jig rising water uniform, rapid flow down, effectively improve the recovery of fine grained useful minerals, fine grained materials beneficiation effect is excellent. 

3, with the characteristics of water saving, continuous work. 

 

4, stroke, stroke time adjustment is convenient, installation and maintenance is simple.

Beneficiation method

Jigging pause ore belongs to readjust the sorting operation, it with water as a separation medium, using the selected in the proportion of gangue minerals difference, carries on the sorting, jig belongs to the diaphragm, stroke and speed according to the proportion of the selected mineral, can be adjusted flexibly, widely used in tungsten, tin, alluvial gold, hematite, brown iron, manganese, titanium, antimony, lead, tantalum, niobium metals such as gravity separation.

Installation and maintenance

1. The equipment should be installed on a horizontal concrete foundation and fixed with ground bolts. 

2. When installing, attention should be paid to the vertical of the main body and the horizontal. 

3. After installation, check whether the bolts in each part are loose and whether the door of the main engine cabin is tightened. If so, please tighten. 

4. Power line and control switch are configured according to the power of the equipment. 

5. After the inspection, the empty load test will be carried out, and the production can be carried out if the test is normal. 

The machine maintenance 

1, all the load bearing for machine, so good lubrication for the bearing life has a great relationship, it directly affects the service life of machine and availability, and requirements into lubricating oil must be clean and seal must be good, the machine’s main oil, all rotating bearing, roller bearing, gear, bearing, sliding plane. 

2. The newly installed tyre is easy to loosen and must be checked frequently. 

3. Pay attention to whether all parts of the machine work normally. 

4, pay attention to check the wear degree of easy to wear parts, pay attention to replace the worn parts at any time. 

5. Put the bottom frame plane of the movable device, and dust and other things should be out so that the movable bearing can not move on the bottom frame when the machine encounters unbroken materials, resulting in serious accidents. 

6, bearing oil temperature rises, should stop immediately to check the reason to eliminate. 

 

7. If there is impact sound when the gear is running, it should be stopped immediately for inspection and eliminated.
