Drumming jigger should include hydraulic drumming, wind drumming and slurry leaf drumming.Slurry leaf drumming jigger has been eliminated, the following mainly introduces the hydraulic drumming jigger.

There is no transmission mechanism in the hydraulic drumming jigger.The water flow under the pressure of 29.48-245.15 kPa opens the flap into the jigging chamber.With the rapid flow of water, the pressure below the flap is reduced, and the water inlet is closed under the action of the spring, and then the pressure rises again.So to the jigging chamber intermittently feeding the rising water flow.Artificial bed is laid on the screen surface, and the ore is discharged through the screen.Because there is no falling water flow, so the bed is looser, the equipment processing capacity is large, often installed in the closed-circuit grinding cycle, used to recover coarse-grained gold or monomer sulphide minerals, reduce over-grinding losses.The machine has compact structure, strong adaptability, high ore dressing ratio, water consumption is not big, the disadvantage is that it can not effectively recover fine-grained heavy minerals.
