New technology and technology for jigging beneficiation (4)

c 1000×1000 double-chamber regenerative jig This machine is similar to the structure of the foreign Wemco-Rermer jig (see Figure 9). The diaphragm is arranged in the same way as the double-chamber lower diaphragm jig. The same, the difference is that there are two eccentric transmissions, one high punch and one low punch. The two work together on a rocking frame to make the cone get a composite vibration, which helps the bed to be loose.
In the processing machine 2 ~ 0 mm oolitic iron ores, using the operating conditions shown in the table, stroke, stroke frequency combination shown in Table 3 the value of 4. Use artificial magnetite as magnetite or hematite. When the ore grade is 35.92% Fe, the selected concentrate grade is 52.94% Fe, the tailing grade is 26.60% Fe, and the operation recovery rate is 58.87%. Due to the poor recovery rate of fine-grained grades and the low processing capacity, the machine has rarely been promoted.

d Round Jig The round jig is developed from the trapezoidal jig. The early round jig used the eccentric link mechanism to drive the vertical diaphragm movement between the chambers. It was used on the tin-making boat in Indonesia and achieved excellent results with a large throughput per unit area. The Dutch company MTE further studied the use of hydraulic transmission instead of mechanical transmission. In 1970, it produced a hydraulic circular jig (IHC, clesveland jig) with a rotating fabric. In the future, it will continue to be improved and become a jig assembled by a plurality of unit jigging chambers. The upper surface may be round or short, and the name is changed to a radial jig (MTE, Radial jig).
China has been developing hydraulic circular jigs since the early 1980s. YT-7750, DYTA-7750 and PY-TA-7750 have been put into use. The dimensions of the equipment are 7750 mm according to the diameter of the trapezoidal jib compartment, the difference being the main shifting device. YT type uses friction disc or tape infinitely variable speed; DYTA is electromagnetic speed regulating motor, PYTA is driven by V-belt, need to change the speed by changing the pulley. The equipment can be composed of 3 chambers (90°), 6 chambers (180°), 9 chambers (270°) or 12 rooms (360°). Each unit is powered by a hydraulic pump station. The appearance of the device is shown in Figure 10.

Slim Rotary Damper mainly used for small diameter, long height space. Shaft Damper is used to dampen drives, control speed, and many other applications. Shaft damper are widely used in invisible screens. Shaft damper can make the movement of structures soft, quiet and safe to mitigate the impact, avoid the damage, increase the mechanical life, reduce noise, and improve product quality.
