Background

The jigging machine is a gravity mineral processing equipment, it utilizes the different sedimentation velocity of mineral of different specific gravity in the vertical alternating rivers, therefore the height that occupies in the jigging machine is different, and the mineral with large specific gravity occupies the lower floor, and the mineral with small specific gravity occupies the upper strata, discharge outside respectively through special discharging device, realize the purpose of light and heavy mineral separation, the jigging machine is applicable to the sorting metal ore, for example contain tungsten, auriferous placer, choice tin ore etc., not only can be used to the fine material of selection, also can be used to the coarse material of selection, the maximum ore feeding granularity is 6-8mm, but under the individual condition of the choice placer, the maximum granularity is 12 mm.

The common jigger drives the rubber diaphragm to do reciprocating motion through the eccentric link mechanism, so as to push water flow to move up and down in the jigger chamber, and further realize the screening of minerals, wherein the rubber diaphragm completes a complete reciprocating motion called stroke, the size of the stroke directly determines the speed and the acceleration of rising water flow in the jigger, and further influences the looseness of a bed layer and the action of the water flow on the minerals, if the stroke is too small, the bed layer is easy to harden, the suction effect under the sieve plate is weakened, the yield is reduced, the recovery rate is reduced, the jigger can even lose the sorting effect seriously, and the sorting effect is not realized.

The stroke of a rubber diaphragm in a common jigger is determined by the length of a cylinder and the radius of a crankshaft in an eccentric connecting rod mechanism, but is limited by mechanical manufacturing capacity and a use place, and the cylinder and the crankshaft in the eccentric connecting rod mechanism cannot be large and long, so that the stroke of the rubber diaphragm is seriously limited, and the production efficiency of the jigger is further influenced.
