The piston type jig is a mechanical equipment used in jigging and beneficiation plants. The key indoor space in the machine is the screening tank, which is called the jig chamber. A fixed or vibrating grate plate is set at the bottom of the room, with the front one weighing the sieve and the rear one weighing the moving sieve. A piston jig is a jig that uses a piston rod that repeatedly moves left and right to create a pulsating beverage by sieving substances (water).

Working principle of piston jig: The piston jig belongs to the groove type re selection machine equipment. All piston type jigs are equipped with jigging rooms, organizations for inciting flowing water fitness activities, and product discharge organizations. The grate plate in the jig room is made of perforated steel plate, manually woven iron stainless steel mesh or grate bars. The flowing water entering the jigging chamber according to the grate plate should cause the material layer to gradually rise with a small aspect ratio and a slight looseness. Dense particles move to the bottom layer due to the high pressure and sedimentation rate of some gases, while particles with relatively low density migrate to the top layer. When the flowing water decreases, fine particles with high density can also enter the next layer according to the gradually close gaps in the material layer, filling the layers according to relative density. The organization that incites flowing water fitness exercise previously selected piston rods. The piston rod chamber is built on the side of the jig chamber, connected to the bottom, and is driven by an axial force mechanical structure to exercise left and right.

The key use of piston jigs is to screen fine coal, so manual material layer screening is often used to discharge heavy raw materials. The piston jig for screening lump coal or lower grade classified coal shall use the blanking hydraulic gate to discharge heavy raw materials. Because piston type jigs have the advantages of simple structure, easy production and manufacturing, small total area, fast factory operation, and low project investment, they are commonly used in small and medium-sized coal mines or coking coal preparation production workshops to screen fine coal.
