CATHAY sawtooth wave jig machine pulsating water flow separation high mineral enrichment efficiency

The sawtooth wave jig occupies a small area and is simple and convenient to operate. It is a new type of efficient, energy-saving and environmentally friendly mineral processing equipment developed and produced in recent years. It has a good effect on the beneficiation of various metal and non-metallic minerals, especially suitable for the beneficiation of fine-grained minerals. It plays an extremely important role in the recovery and treatment of metal smelting slag and mine tailings treatment.
product introduction
CATHAY sawtooth wave jig: precise power for heavy mineral sorting
1. Sawtooth wave pulsation technology, reshaping sorting efficiency
The core advantage lies in the unique sawtooth wave water flow design - the diaphragm is driven by the eccentric wheel transmission device to produce a sawtooth pulsating water flow of "rapid rise and slow fall" in the jig chamber. This water flow characteristic allows heavy mineral particles to obtain sufficient buoyancy and suspension in the rising stage, and settle rapidly due to gravity in the descending stage. The stratification boundary with light minerals is more than 30% clearer than that of the sine wave jig. The mineral enrichment rate of a single device is increased by 15%-20%, which is especially suitable for the sorting of minerals with obvious density differences.
2. Accurate stratification, significant improvement in the recovery rate of heavy minerals
Under the periodic action of the pulsating water flow, the mineral particles are accurately stratified in the jig chamber according to the density difference: high-density useful minerals (such as gold, tungsten, tin, iron, etc.) quickly settle to the bottom layer and are discharged by the ore discharge device as concentrates; low-density gangue minerals remain in the upper layer and are discharged with the tailings. After sorting, the concentrate grade can reach 5-10 times that of the original ore, and the tailings yield is reduced by 20%. For heavy minerals with fine-grained distribution, the recovery rate is 8%-12% higher than that of traditional jigs, which greatly improves resource utilization.
3. Adapt to multiple types of heavy minerals and have a wide range of application scenarios
Specially designed for heavy mineral sorting, it can efficiently process metal ores such as placer gold, tungsten ore, tin ore, iron ore, and manganese ore. It can also enrich rare minerals such as diamond, zircon sand, and monazite. It is widely used in placer mining, vein ore re-selection, tailings recovery and other fields. Whether it is coarse particles (2-50 mm) or fine particles (0.1-2 mm), targeted sorting can be achieved by adjusting the pulsation frequency (30-60 times/minute) and stroke (5-25 mm), which is adapted to the processing needs of minerals of different particle sizes.
4. CATHAY exclusive structure, leading durability in the industry
The jigging chamber is welded with 16mm thick wear-resistant steel plates, and the inner wall is lined with a high-elastic rubber layer. The impact resistance and wear resistance are 50% higher than ordinary equipment, and it can withstand long-term erosion of high-hardness mineral particles. The eccentric transmission system uses CATHAY customized bearings with a precision level of P5, which runs smoothly without jamming and reduces the failure rate by 40%. The diaphragm is made of oil-resistant rubber material with a service life of more than 8,000 hours, reducing downtime losses caused by frequent replacement.
5. Flexible operation and intuitive parameter adjustment
Equipped with a digital control panel, the pulsation frequency, stroke size and discharge speed can be accurately adjusted by the knob. The parameter setting range is wide and can quickly adapt to the sorting requirements of different types of ores. The equipment is equipped with a transparent observation window to observe the stratification status of the ore layer in real time. Operators do not need professional skills to get started. They can operate independently after 30 minutes of training, which reduces the threshold for production employment.
6. Low consumption and energy saving, controllable operating costs
The drive motor adopts the YE3 high-efficiency energy-saving model, which has a power reduction of 15% compared with traditional equipment. When running at full load, it can save more than 3,000 degrees of electricity per year. The equipment has a compact structure and occupies an area 25% smaller than the jig with the same capacity, saving plant space. There are few wearing parts and low procurement costs. Daily maintenance only requires regular inspection of the lubrication of transmission parts and the wear of diaphragms. The annual maintenance cost is controlled within 3% of the total equipment price.
7. Modular design, capacity configuration on demand
It provides single-chamber, double-chamber, four-chamber and other specifications. The single-unit processing capacity covers 0.5-50 tons/hour, which can be flexibly combined according to the scale of the mine. When multiple chambers are linked, it can realize the continuous operation of roughing and fine selection, reduce the intermediate transfer link, and increase the sorting efficiency by another 10%. The equipment installation does not require a complex foundation. The modular splicing design makes it more convenient to increase and decrease equipment during the expansion of the production line, meeting the production capacity requirements of mines at different stages.
8. CATHAY brand guarantee, worry-free full-cycle service
Each sawtooth wave jig machine undergoes 72 hours of no-load test run and 168 hours of material test to ensure that the factory performance meets the standards. We provide on-site installation and commissioning, special training for operators, free inspections twice a year, and 7×24-hour technical hotline response to fault repairs. We promise to provide on-site repairs within 4 hours in provincial capitals and 12 hours in prefecture-level cities, so that customers can produce without worries.
