Special screening equipment for gold dressing
   1.ZS linear vibrating screen The vibrating screen is designed by China Nonferrous Institute, internal machine, Jilin prospecting and milk machine, suitable for screening, grading, deliming, washing and dewatering of raw ore, especially as carbon slurry. Factory chip removal, safety inspection, separation of gold and carbon, etc.
The sieve belongs to a dual-mass inertially driven resonance type vibrating screen. Due to the guiding action of the leaf spring, the screen body moves linearly. A tuning plate is arranged on the sieve body to change the number of the tuning plates, and the amplitude can be conveniently adjusted. There are four vibration isolation springs with low rigidity, and the dynamic load transmitted to the foundation is small.
ZS type vibrating screen has the following characteristics: 1 low energy consumption, the general installation power is 20% of the self-centering vibrating screen; 2 ground-to-ground transmission load is small, suitable for installation on the floor; 3 simple structure, no transmission parts, maintenance work Small amount, reliable work; 4 amplitude adjustable.
The technical parameters of the ZS type vibrating screen are listed in Table 1, and the external dimensions are shown in Figure 1 and Table 2.
2. DZSF- (IV) Motor shaker which is one of Jilin mineral prospecting production plant conventional screening equipment, in particular can be used in addition to CIP plant cuttings, security checks, loaded carbon separation. The device has a simple structure, no transmission parts, small maintenance workload and reliable performance.
This series of motor vibrating screens has five kinds of vibration forms: motor bottom, side bottom, side center, side top and top, and they are represented by I, II, III, IV and V respectively.
Working principle: This series of motor vibrating screen adopts single-mass far-resonance double-motor self-synchronous reverse-rotating vibration motor. The unbalanced mass on the shaft of the vibrating motor generates inertial force and lateral force, which are eliminated by the reverse rotation of the two motors. Vertically perpendicular to the direction of the two motor shafts, the body produces a cyclical vibration at a certain angle to the horizontal plane, continuously throwing the material forward to achieve vibration screening. A schematic diagram of the structure is shown in Figure 2, and the technical parameters are shown in Table 3.
Model meaning DZ - screening; SF - motor vibration. I——linear vibration of the motor under the motor; II——linear vibration of the motor side under the load; III——linear vibration in the motor side; IV——linear vibration on the motor side; V——linear vibration on the motor.
3. LXS type spiral screen This is one of the indispensable equipments for the whole mud cyanide carbon slurry method of Jilin prospecting production. It can remove mineral gravel, wood chips, sundries, etc., separate gold and coal slurry, and recover fine particles. carbon. The machine has the characteristics of small power, reliable operation, good screening effect and low carbon wear rate.
Model meaning example LXS600×1300: LX – spiral; S – sieve; 600 – large head diameter 600mm; 1300 – spiral length 1300mm.
The main technical parameters are shown in Table 4, and the structure is shown in Figure 3.
