New technology and new technology of jigging beneficiation (6)

Sorting machine to be tested in a tin-containing sulfide ores PBM manufacturers, the results obtained, the processing time of -3.5 + 1.5 mm size fraction of metal ore recovery rate slightly higher than the working Jig leather, while the water The consumption can be reduced by more than 75; the tailings used for sweeping the -3.5 mm work leather jig can directly discard the final tailings and obtain the hair concentrate and the middle mine; instead of the cone concentrator pair -1.5 mm For ore sweeping, the recovery rates of tin, lead and zinc operations can be increased by 4.12%, 5.54% and 3.07%, respectively. It shows that the machine has good adaptability in addition to superior technical and economic indicators.
f ZXY series round jig This is the lower-moving diaphragm jig of the upper drive made by China in the early 1980s. The structure is shown in Figure 13. The lower movable cone is moved up and down by the vertical axis through the cam lever system. The cam pulsates the water flow in a sawtooth curve. The raw material is fed from the upper central chute, and the heavy product is discharged through the sieve. It can be used for the selection of tungsten, tin, iron and sand mine. The technical performance of the equipment is shown in Table 8.

C Side-moving diaphragm jig The diaphragm of this jig is mounted vertically on the outside of the box (outer diaphragm) or in the two jigging chambers (inner diaphragm).
α Rectangular Side-Moving Diaphragm Jig The rectangular side-moving diaphragm jig has a rectangular screen shape with a single row of two chambers and a double row of four chambers. Figure 14 is an outline drawing of a four-chamber jig. The tank is suitable for both coarse-grained (12~3mm) and fine-grained (3~0mm) structures. The former heavy product is discharged by the body (see Figure 14), and the latter are discharged separately. It is recommended to use the stroke when handling the coarse-grained grade: 40 mm for one chamber, 35 mm for two chambers, 160 and 200 beats/min for the punches, and 8-12 tons/set for the treatment volume (700 x 900 mm for four chambers). Water consumption is 60~90 tons/set. The stroke is recommended for the treatment of fine-grained grades: 25 mm for one chamber, 20 mm for two chambers, 200 and 250 beats/min for punches, and 5 to 10 tons/set for treatment. When water consumption is 20 to 50 tons/set. . The aircraft in our country more used to treat iron, tungsten, tin, niobium, tantalum and other minerals. In production, the machine can also be used in series to expand the processing capacity. Table 9 lists the production examples of the four-chamber jig treatment of the Meishan iron ore hematite.

China's gold mining vessels also use a 1000×1000 side moving diaphragm jig, commonly known as the Yuba jig. The structure is similar to the above-mentioned rectangular jig, except that the flow direction of the ore flow is perpendicular to the diaphragm. Technical performance is listed in Table 10.
