1、 Downward moving jig | Upward moving diaphragm jig | Overview of diaphragm jig

Diaphragm jigs are divided into two types: left type jigs and right type jigs. This diaphragm jig is a fixed sieve. Suitable for selecting metal ores, such as tungsten and gold bearing placers, and selected tin ores. It can be used for selecting both fine and coarse materials, with a maximum feed particle size of 6-8mm. However, in some cases of selecting placers, the maximum particle size is 12mm.

2、 Downward moving jig | Upward moving diaphragm jig | Structural composition of diaphragm jig

The main components include the body, transmission device, water separator, diaphragm, and valve. The body has two sizes of skip buckets, each of which is divided into two parts: the jig area and the diaphragm area using a bottomless diaphragm. The jigging process is carried out by the agitation of the medium (water) caused by the reciprocating motion of the rubber diaphragm up and down. The electric motor drives the large leather wheel to rotate through a triangular belt, causing the connecting rod on the eccentric shaft to move up and down. The rocker arm connected to this connecting rod also moves up and down. There are also two connecting rods on the rocker arm that are connected to the rubber diaphragm, allowing the diaphragm to achieve reciprocating motion up and down for jigging. According to the particle size of the processed ore, the stroke of the connecting rod can be changed and different strokes can be selected to achieve the best jigging effect. The method to change the stroke frequency is to replace the small pulley, which can be divided into two types: 322 strokes per minute; 420 times/minute. The stroke selection method includes loosening the set screw and nut, pulling out the positioning pin, and rotating the relative position between the eccentric adjustment sleeve and the eccentric shaft. There are 11 different strokes (0-25.3mm) available

3、 Downward moving jig | Upward moving diaphragm jig | Working principle of diaphragm jig

Due to the addition of a sieve above the working sieve, the diaphragm jig can be used to handle materials with uneven particle size. (Note: This screen may not be supplied according to order requirements) After the selected raw ore is sent to the jigging chamber, due to the stirring effect of the diaphragm, the ore particles are layered according to their specific gravity in the medium; Fine and heavy ore particles pass through the gaps and sieve holes of the artificial bed particles and settle in the ore storage of the jig bucket. The coarse and light ore particles (minerals) in the upper layer are washed by the medium flow towards the discharge port at the end of the sieve. Due to the position of the rear jig chamber being 50mm lower than the front jig chamber, the light ore particles overflow through the tail plate of the front chamber and enter the rear chamber, where they are once again subjected to jigging. The position of the tailboard can be adjusted as needed to control the size of the ore discharge. The concentrate in the storage hopper is regularly discharged by the discharge pipe.
