The drive system, which is the mechanical hydraulic form, is powered by electric motor. The output shaft of the reducer drives the cam to rotate through the shift gear. The cam drives the plungers of each main transmission oil cylinder to do the periodic reciprocating movement which transforms the electric energy into mechanical energy and then into hydraulic energy. The hydraulic energy drives the slave cylinder movement which drives the cone of jig machine to do the pulsing movement up and down.
The jig frequency of DYTA-7750 is regulated steplessly through the electromagnetic speed regulating asynchronous motor from 0-90 times/min. The jigging chamber is unit combination, each unit is composed of 3 jigging sections. Each jigging section is similar to a trapezoidal jig machine. The sections could form a round or fan shape according to the capacity and or the configuration requirements.
At present, the hydraulic radial jig has been widely applied on dredgers as roughing concentration equipment for ore, tin ore, diamond ore, tungsten ore, hematite ore, and so on in foreign countries. The mining equipment our country introduced from Dutch which were applied on three 300 liters gold dredger is just this kind of hydraulic radial jig.

Description
This portable gold trommel plant is self contained, and with its 1-5t/h capacity, it is ideal for testing gold values or for small production operations. The unique water supply and reclamation unit allows operation where water is not available.
A spray bar with its own adjustable water valve goes the length of the trommel. Next, the material approaches the 8mm holes where anything under 8mm gets washed down onto the oscillating sluice, and larger material works its way to the end of the trommel. A nugget trap will catch any heavies and the lighter material will go out the tail cone to the rock chute and discard tray. The oscillating sluice has settings for stationary, short, and long strokes. The removable sluice has artificial turf, riffles mounted on expanded metal and toggles to secure it onto the place. Any light material that gets washed off the sluice goes into the de-watering screw.
The simplicity of this equipment makes it the leader in the field of small portable placer equipment. Industrially built, it is easy to maintain and powered by either an electric or diesel engine which is easily removable by removing the snap pin and sliding out the motor mount. It was designed that way so you can easily take it with you at the end of the day to cut down on theft. On engine runs both the gear reducer and water pump using a B-width belt.

Description of magnetic separator
The Magnetic Separator can separate raw materials with different magnetic rigidities. The machine works under the magnetic force and machine force. Magnetic Separators are designed to recover ferromagnetic materials. The separators are available in designs and sizes to provide solutions for all applications. The heart of each separator is the magnetic system with its unique design, which has a proven record of high efficiency. The Magnetic Separators are available in cyclic design with process vessel diameters smaller than 3mm. Magnetic Separator is one kind of efficient equipment for processing fine, feebly magnetic minerals, such as hematite, limonite, wolfram, limonite, and tantalum-niobium, etc
Structure of magnetic separator
1. CTB series magnetic separator consists of magnetic drum, tank body, support, feed box, discharge box (ore concentrate box), drive motor, motor reducer, control box, etc.
2. The magnetic drum is made of stainless steel and covered with wear resistant rubber.
Working Principle of magnetic separator
When the raw materials flow into the tank body of the magnetic separator.
1. Firstly, the flowing direction of the raw materials is the same as the rotary direction of the magnetic drum, the iron magnetite materials are attracted to the surface of drum. This is the first separation.
2. In the second step, the flushing water below flushes the raw materials back is the second separation. This time the flowing direction of the raw materials is opposite to the rotary direction of the magnetic drum. Then along with the rotation of drum, the iron magnetite materials on the surface of drum will finally leave the magnetic field and fall in the ore concentrate box under the effect of gravity. The flushing water above helps to flush the iron magnetite into the ore concentrate box. The weak magnetic and non-magnetic materials can not be attracted and will flow to the discharge pipe as tailings.
