The principle of the sawtooth-wave jig machine:
The sawtooth-wave jig machine is based on the stratification principle of the jigging bed theory and achieves mineral separation through a unique sawtooth-wave pulsation curve. Its core lies in the asymmetric design of water flow velocity and duration: the upward water flow is rapid and short-lived, causing the bed to quickly loosen and the mineral particles to become fully suspended; the downward water flow is slow and prolonged, providing sufficient settling time for heavy minerals while allowing light minerals to be discharged with the water flow. This design overcomes the drawback of traditional sine-wave jig machines, where the upward and downward water flows are symmetrical, enhancing bed looseness, mitigating suction effects, and enabling full settling of heavy mineral particles, thereby improving ore separation efficiency and recovery rate.

Advantages of the sawtooth-wave jig machine:

1. Significant improvement in ore separation efficiency and recovery rate
2. By optimizing water flow characteristics, the sawtooth-wave jig machine achieves a more uniform distribution of mineral particles and better stratification effects. Industrial experimental data show that its recovery rate is significantly higher than that of traditional jig machines: tin ore by 3.01%, coal by 6.3%, tungsten ore by 5.5%, lead ore by 1.63%, and zinc ore by 2.04%.
3. The unique pulsation curve and water flow control enable full settling of heavy minerals and effective discharge of light minerals, greatly enhancing resource utilization.
4. Outstanding energy-saving and environmental protection performance
5. Water consumption is reduced by 30%-40%, lowering water resource consumption and making it particularly suitable for use in water-scarce areas.
6. The footprint is reduced by one-third, saving space and reducing infrastructure costs.
7. An electromagnetic speed-regulating motor enables stepless adjustment of the stroke frequency and adjustable stroke, further optimizing energy consumption and aligning with energy-saving and environmental protection trends.
8. Strong adaptability and wide application range
9. It is suitable for the separation of fine-grained minerals, such as placer gold, tungsten-tin ores, and tantalum-niobium ores, with significant recovery rate advantages.
10. It can also be used for the separation of coarse-grained materials, with a wide feed particle size range (6-8 mm, and up to 12 mm in individual cases).
11. It is widely applied in the separation of metallic ores (such as tungsten, tin, gold, iron, and manganese) and non-metallic minerals, as well as the comprehensive recovery and utilization of smelting slags (manganese slag, chromium slag, and stainless steel slag).
12. Simple operation and low maintenance costs
13. It is easy to install, operate, and maintain, reducing labor and operational and maintenance costs.
14. The equipment has stable performance and is suitable for both small-scale gravity separation and large-scale industrial production.
15. Significant economic and social benefits
16. Improving ore separation efficiency and recovery rate directly increases the economic benefits of enterprises.
17. Enhanced resource utilization reduces tailings discharge and environmental pollution, aligning with sustainable development requirements.
