DYTA7750 hydraulic radial jigs are widely used on mining vessel at home and aboard as roughly selected equipment to sort ores such as alluvial gold, tin, diamond, tungsten and hematite.
DYTA7750 hydraulic radial jigs are developed from circular jigs. They are composed of two parts. i.e., drive and tank. The drive is of mechanical hydraulic type whose power is provided by motor. Through speed-change mechanism, the output shafts of speed reducer bring along the rotation of cam which drive cyclical alternating movement of every plunger of drive cylinder so as to convert electric energy to mechanical energy and then to hydraulic energy. Through hydraulic pipes and all kinds of valves, the movement of slave cylinder is driven and the fluctuation of the jig’s cone is brought along.
The jig frequency adjustment of DYTA7750 jig has two kinds of forms. According to difference in jig frequency adjustment mechanism, DYTA7750 jigs have two models: DYTA7750 and PYTA7750. DYTA7750 jigs adopt electromagnetic speed regulating asynchronous motors to realize the adjustment of jig frequency which belongs to stepless adjustment. The adjustable range of jig frequency is 0-90 times per minute. PYTA7750 jigs adopt common squirrel-cage asynchronous motors. The power is transmitted through belts and jig frequency is adjusted through the replacement of belt pulley. This belongs to step adjustment. The machine is equipped with three kinds of belt pulleys which enables the jig frequency of the jig to be 60 times per minute, 70 times per minute and 80 times per minute. Besides, belt pulley of a certain jig frequency of between 60 and 90 times per minute can be provided according to the needs of users. The two types of models have advantages of their own. Thus, the users can make their choice according to their own actual needs. The tank is of unit combination type. Every unit consists of three jigs. Every room is equipped with one trapezoidal jig. It can be made circular or fan shaped according to the handling capacity and configuration requirements of equipment. The advantage to adopt combination type is it is easy for fabrication, transportation and installation.
