Ore dressing by Gravity Jig is considered as one of the major means for gravity beneficiation with the process characteristics being continued feed of ores to be beneficiated onto screen plate in Jigging Chamber, forming thick material layer. Upward flow is injected via screen plate periodically, allowing the lift of bed layer to be loose and flow to drop ( or stop rising). During this process, grains of different densities will displace relatively, with the heavy materials bring delivered into lower layer and the light material being transferred into the upper layer. Concentrate and tailings will be obtained after their being discharged respectively.

Sawtooth-wave Jig is a new type of energy conservation and highly efficient gravity separation equipment and developed based on the traditional Sine Wave Jig. The difference between Sawtooth  Wave Jig and Sine Wave Jig is that the pulsation curve for jigging is of sawtooth wave shape ,with speedy upward flow and slow downward flow. Bed layer is elevated integrally and slowly dropped with a long effective loose time, allowing significant increase of handling capacity for unit screen surface, decrease of lower limit of grain size recovery and large save of make-up water for undersize fraction. Industrial tests carried out of Sawtooth Wave Jig and Sine Wave Jig for comparison showed that the recovery rate for operation of Sawtooth Wave Jig is raised by Sn: 3.01%, WO 3:5.5%, Pb:1.63%, Xn:2.04% with water consumption being decreased by 30 – 75%.

Ore dressing by Sawtooth Wave Jig is capable of handling almost full sizes of mineral materials other than very fine material. It features simple process operation, heavy duty equipment handling capacity with final products being obtained through one time separation. Therefore, it has found a wide application in production. It is regarded as one of major means to cope with metallic ores such as iron and manganese ores of coarse, moderate and fine sizes and has found significant use in beneficiating tin and tungsten ores. Moreover, Jigging Method also can achieve a good result in processing primary ores bearing gold, tantalum niobium, titanium, zirconium and chrome and sand stones.

More density minerals to be separated in ores have, wider range the feed sizes have. For gold bearing placer, when feed grain size is less than 25mm, separation may be carried out without size classification with the lower limit of recovery up to 0.05mm. For ordinary metallic ores, size classified separation is conducted to effectively improve indexes for separation and to enhance handling capability for the equipment.

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.

This  hydraulic system is mainly composed of hydraulic power unit, actuating  cylinder, slave cylinder, hydraulic piping and control valves. The hydraulic  power unit is mainly used to add oil. The main function of actuating cylinder  is to convert mechanical energy to hydraulic energy through cam’s propelling of  plunger. The main function of slave cylinder is to convert mechanical energy to  hydraulic energy by the movement of plunger driven through the pressure oil  transmitted by the actuating cylinder.

Its  hydraulic transmission processes are as follows: The cam 12 rotates and drives  the plunger of actuating cylinder 11 to produce pressure oil. It, through the  one-way throttle valve 10 to the upper chamber of slave cylinder 13, drives the  piston of slave cylinder to move downward and bring along the cone 1 to move  downward (it is also pressed downward with the weight of lower cone 1 and the  gravity of water and mineral), press the oil in F chamber of the slave cylinder  to get the lower chamber to produce high-pressure hydraulic oil. There has  already been leather bag with oxygen of 3.5-4MPa in the compressed high-pressure  accumulator 3 which accumulates energy. When the cam rotates from the highest  point to the lowest point, the actuating cylinder plunger is pulled outward and  the high-pressure accumulator releases energy. The high-pressure hydraulic oil  pushes the piston of the slave cylinder upward and brings along the upward  movement of cone 1. In this ways, cyclic up and down movement (pulsation) of  cone 1 is achieved.
