What is Jigger Machine?
In traditional mineral processing production, fine sorting equipment such as shaking tables and spiral chutes is only suitable for fine-grained materials, with extremely low efficiency when dealing with coarse ore particles. For bulk raw ore and large-particle heavy minerals, flotation equipment requires a large amount of chemical reagents, resulting in high operating costs and environmental pollution. Many mines face the dilemma of low coarse ore processing capacity, serious resource waste and low roughing efficiency.
Our Mining Jigger Machine perfectly solves the above industry pain points. It is specially developed for coarse and medium-grained mineral rough separation, relying on pulsed water flow to stratify minerals by specific gravity difference. High-density valuable minerals sink to the bottom layer for concentration, while low-density gangue floats and is discharged. With far larger processing capacity than other gravity equipment, it completes high-efficiency bulk roughing, discards useless gangue in advance, reduces subsequent fine sorting pressure, and greatly improves overall plant beneficiation efficiency and economic benefits.
Core Structural Composition & Advantages of Jigger Machine
1. Optimized Pulsating Water Flow System
Equipped with professional cam-driven pulsating mechanism, it generates stable and adjustable periodic water flow fluctuation. The unique water flow rhythm fully loosens ore particles without particle sinking disorder, forming accurate density stratification. It effectively improves sorting precision and avoids material mixing caused by unstable water flow.
2. High-Strength Wear-Resistant Sieve Plate
The sieve plate is made of thickened high-quality steel with anti-wear and anti-corrosion treatment. The uniform sieve hole distribution ensures smooth water flow and stable material support. It resists long-term impact and scouring of coarse ore particles, with strong durability and long service life, reducing frequent replacement costs.
3. Adjustable Frequency & Stroke Mechanism
The jigger is equipped with adjustable stroke and frequency device. Users can flexibly adjust pulsation frequency and stroke amplitude according to ore particle size, density difference and processing volume. It adapts to different coarse and medium mineral sorting requirements, with strong on-site adaptability.
4. Automatic Continuous Discharging Structure
Adopts intelligent automatic discharging system for bottom concentrate, realizing uniform and continuous ore discharge. It avoids material accumulation and stratification disorder caused by intermittent discharging, ensuring long-term stable and consistent sorting indicators of the equipment.
5. Integrated Sealed Tank Body
The overall welded steel tank body has good rigidity and strong shock resistance. The sealed structure prevents slurry splashing and water flow loss, ensuring stable water level and sorting environment. The compact layout saves plant floor space and facilitates production line assembly.
6. Low-Power Stable Transmission System
Equipped with energy-saving motor and optimized cam transmission structure, with low power consumption and large driving force. The operation is stable with low noise and small vibration. The mechanical structure is simple with few vulnerable parts, greatly reducing daily failure rate and maintenance difficulty.
Core Product Advantages of Jigger Machine
1. Ultra-Large Single-Machine Processing Capacity
As the core bulk roughing equipment in gravity separation, the jigger machine has a processing capacity several times higher than that of shaking tables and spiral chutes. It can handle large-volume coarse ore raw materials efficiently, greatly improving the hourly throughput of the mineral processing plant and suitable for large-scale mining production lines.
2. Wide Particle Size Adaptation Range
It is specially suitable for 0.5-30mm coarse and medium-grained minerals, making up for the defect that fine sorting equipment cannot handle large particles. It covers coarse ore roughing and medium ore separation scenarios, with strong material adaptability and wide application range.
3. Pure Physical Separation & Zero Pollution
The whole sorting process relies entirely on water flow pulsation and gravity difference, without adding any flotation chemicals or heavy media. No chemical residue or environmental pollution is generated. The sorting water can be recycled and reused, fully meeting global green mining environmental protection standards.
4. High Rough Concentration Efficiency & Low Waste
It can quickly and effectively discard a large amount of low-density gangue in advance, greatly reducing the feeding volume of subsequent fine sorting equipment. It improves the grade of raw ore entering the fine separation process, significantly increases final concentrate recovery rate, and reduces resource waste.
5. Low Operating Cost & Easy Maintenance
No reagent consumption, low power consumption, and few mechanical vulnerable parts. The equipment structure is simple, daily maintenance is convenient, and no professional operation technology is required. It greatly saves labor, material and energy costs for the mine, with a short investment return cycle.
6. Perfect Matching with Gravity Separation Line
It forms a scientific and efficient roughing-then-refining process with spiral chutes and shaking tables. Jigger completes bulk coarse ore rough separation, and fine equipment completes high-precision refining, maximizing overall beneficiation efficiency and economic benefits of the production line.
Working Principle & Production Flow of Jigger Machine
Core Working Principle
The Jigger Machine adoptspulsating water flow gravity stratification technology. Driven by the transmission mechanism, the sieve tank generates regular up-and-down reciprocating motion to form stable vertical pulsed water flow. After raw ore enters the jigger tank, mineral particles are fully loosened and stratified under the action of rising and falling water flow.
High-density valuable minerals settle rapidly to the bottom of the sieve plate and are discharged as concentrate through the discharging mechanism. Low-density gangue and impurities float on the upper layer and overflow with water flow as tailings. The whole process realizes continuous automatic feeding, stratification, sorting and discharging, completing high-volume and high-efficiency physical gravity separation.
