Sawtooth waveform jig
Most of the above-mentioned conventional jigs are circumferentially eccentrically driven, and the jigging pulsation curve is a sinusoidal waveform, and the rising and falling speeds of the cone are equal, and the rising water flow and the descending water flow intensity are substantially the same. The pulsating characteristic curve of the new sawtooth waveform jig is a sawtooth waveform (ie, a differential jig curve), which can make the cone fast rise and slow down, that is, the pressure is fast and the suction is slow. The first half of the pressure stroke is accelerated, the second half is decelerated, and the suction is constant. This curve is theoretically consistent with the grading rule of the jigging bed, which helps the looseness of the bed minerals and the stratification of the ore particles according to the density, which can make the heavy mineral particles in the fine-grained grade fully settle, and reduce the bed The strong suction of the layer can greatly reduce the supply of water under the screen. This jig with a poor arterial curve is characterized by the ability to sort the raw materials with a wide range of grain sizes, improve the sorting ability, increase the recovery rate, save electricity, and save water (the water consumption is 1/2 of the traditional jig). ~2/3). The sawtooth waveform jig is a major development in jig equipment.
In the 1960s, the hydraulic radial (circular) jig developed by the Netherlands and the United States first applied the sawtooth waveform working curve. This type of jig has been used successfully on gold mining vessels and has been promoted and used in the world. It has also promoted the development and development of different types of sawtooth waveform jigs.
In 1981, the North Mine Institute and Shenye cooperated to survey and digest the imported hydraulic radial (circular) jig, and successfully manufactured the YT7750 hydraulic radial jig, which was used on gold mining vessels. However, the supply of spare parts is difficult, and there are some problems in the transmission system. Therefore, the North Mine Institute cooperated with the Pinggui Machinery Factory to improve it. In 1985, the DYTA-7750 and PYTA-7750 hydraulic radial jigs were successfully produced. Round jig), in 1986-1987, developed three new sawtooth jigs and improved a fake sawtooth waveform jig. It has become a series of products and is widely used in China.
At present, the sawtooth waveform jig is mainly produced by Pinggui Machinery Factory. The transmission system has two kinds of mechanical-hydraulic transmission and mechanical drive. Considering the cost of equipment, the mechanical-hydraulic transmission method is generally used for large jigs and mechanical drives. The method is generally used for small jigs. The hydraulic radial jig produced by the factory is mainly used on gold mining vessels. The technical parameters are listed in Table 1. The machine has 3~12 rooms. The structure and dimensions of the three-chamber jig are shown in Figure 1. Others The structure and outer dimensions of each room jig are the same, except that the larger the number of rooms, the larger the floor space.
The JT type jig produced by Pinggui Machinery Factory consists of a slot bolt, a strut, a chassis, an electromagnetic speed regulating motor, a coupling and a cam box. The cone is connected to the cam box through the connecting block, and the rubber discharge tube is discharged under the cone to discharge the concentrate, which can be continuously discharged. Among them, JT-0.15 jig is also known as ST multi-function jig. Its pulsation curve has sine wave, sawtooth wave and flat peak sawtooth wave. The trough shape has trapezoidal and rectangular shape. The stroke and stroke can be steplessly adjusted. It can be used for upper or lower screen discharge. It is an ideal test equipment that can adapt to different conditions.
The JT type sawtooth wave jig produced by the factory and its technical parameters are listed in Table 2. The structure, dimensions and installation base dimensions of the three specifications are shown in Figures 2 to 4, respectively. It is mainly used for sorting gold, tungsten ore, tin ore, hematite beach placer and the like, and serves as a master board with gold sorting equipment.
