Jigging Separator Machine Overview

A jigging machine is a piece of equipment that implements the jigging process. The process in which the material is sorted according to density differences, mainly in a vertically rising and falling stream of variable speed media. The difference in size and shape of the material has an effect on the result of the separation. The medium used in jigging can be either water or air. When water is used as the sorting medium, it is called hydraulic jigging; when air is used as the sorting medium, it is called wind jigging.

What are Benefits of Using Jigging Machine?

Why do modern plants still rely on technology that has existed for decades? The answer lies in operational economy.

• 1. Low Operating Cost:The jig consumes relatively low electricity. Unlike a ball mill that grinds rock, the jig simply moves water. Furthermore, it requires no chemicals. It uses recycled process water, making it environmentally friendly and cheap to run.
• 2. High Capacity:A single large Trapezoidal Jig can process up to 100 tons per hour. This makes it an excellent “Rougher.” By discarding 60-70% of the light waste rock early in the process, the plant saves energy on crushing and grinding downstream.
• 3. Robustness:Jigs can handle a wide range of feed sizes (from 2mm to 30mm). They are tolerant of feed fluctuations. If a surge of ore comes down the conveyor, the jig handles it better than a sensitive shaking table or spiral chute.
• 4. Simplicity:Maintenance is straightforward. There are no complex electronics or delicate sensors. The main wear parts are the rubber diaphragm and the screen mesh, both of which are easily replaceable by site mechanics.

Jigging Separator Machine Classification

According to the different equipment structure and water flow movement, it can be roughly divided into the following categories: piston jigger, diaphragm jigger, air pulsation jigger, and dynamic screen jigger.
Selection Guide
Jig machine selection steps: first and jig machine manufacturer telephone contact, by asking some technical questions, you can roughly understand whether this manufacturer is professional, the next step is to carry out beneficiation tests, this step is critical, you bring ore to the jig machine manufacturer, the general situation is 30-40 kg of raw ore, the regular manufacturers have small jig machine available for free test, the test is not as good as the actual production indicators, but also The test is not as good as the actual production indicators, but also from the side to grasp the ore beneficiation indicators, and jigger manufacturer’s technology is perfect, if the test link can reach the ideal indicators, then this manufacturer has a certain strength, and then is to order equipment links, look at the quality of jigger equipment, external viewing jigger working principle is reasonable, and according to your site conditions for improvement, of course, the important issue is the price, the price is also based on the above The price is also based on the above cases of negotiation, the final order products, jigger manufacturers have professional technical staff to install and commission until you produce qualified products.

Which Industries and Materials are Jigging Separators Used for?

The Jig Concentrator is versatile, but it excels where there is a significant density difference between the valuable mineral and the waste rock (gangue).

• 1. Industrial Minerals (Barite & Fluorite):This is the classic application. Barite (Specific Gravity ~4.5) is much heavier than the surrounding rock (~2.7). A jig can easily produce high-grade barite concentrate used in drilling muds without any chemical processing.
• 2. Manganese Ore Beneficiation:Manganese oxide often occurs as lumps mixed with clay and silica. The Jigging Separator is the primary method for upgrading manganese ore, removing the lighter silica and boosting the Manganese (Mn) content to salable levels.
• 3. Alluvial Gold and Diamond Washing:In placer mining, gold and diamonds are heavy particulates hiding in river gravel. Jigs are used to wash away the large gravels (waste) while capturing the heavy concentrates in the “hutch” at the bottom.
• 4. Slag Recycling:Smelting slag often contains trapped droplets of ferrochrome or silicomanganese alloy. Because the alloy is heavy metal and the slag is light glass, jigs are perfect for recovering metal from crushing slag.
• 5. Coal Washing:Jigs are historically the most common method for separating coal (light) from shale/sulfur (heavy). In coal preparation, the “valuable” product floats to the top, while the waste sinks—the reverse of metal mining.

Particle Size Matters: What is the Ideal Feed Range for a Jig?

Understanding particle size limitations is critical for success. The jig is not a catch-all solution for every size fraction.

• The Sweet Spot:Jigging works best on Coarse to Medium particles, typically ranging from 2mm to 30mm.
  • Coarse Fraction (+10mm): Requires a lower frequency of pulsation (fewer strokes per minute) but a larger amplitude (longer stroke).
  • Fine Fraction (-4mm): Requires high-frequency, short-stroke pulsation to prevent the bed from becoming too compact.
• The Limitation:Jigs struggle with very fine material (Slimes < 0.2mm). At this size, surface tension and water viscosity dominate gravity. The tiny gold or mineral particles simply float away in the water flow regardless of their density. For fine material, a Shaking Table or Centrifugal Concentrator is required.
• Screening is Essential:To maximize efficiency, ZONEDING recommends screening the feed. Feeding a mix of 20mm rocks and 1mm dust into the same jig is inefficient. It is better to use a Vibrating Screen to split the feed into two fractions (e.g., 2-8mm and 8-20mm) and send them to two separate jigs adjusted for those specific sizes.

Structure of a Jigging Separator Machine

What are Key Components of Jigging Separators?

While robust, the machine is an assembly of precise mechanical parts.

• 1. The Jig Box (Tank):Usually divided into two or more chambers (cells). It holds the water and the ore bed. ZONEDING often designs these with a trapezoidal shape to accommodate flow dynamics.
• 2. The Screen Plates:Or perforated sheets. These hold the ore bed. The hole size corresponds to the concentrate size.
  • “Through-the-screen” jigging: The heavy concentrate is smaller than the screen holes and falls through into the hutch.
  • “On-the-screen” jigging: The concentrate is larger than the screen holes and is drawn off from the top of the bed.
• 3. The Diaphragm and Connecting Rod:This is the “heart” of the machine. An eccentric gear moves a rod up and down. This rod pushes a rubber diaphragm, which acts like a giant plunger, forcing the water in the tank to pulsate.
• 4. The Valve (Rotary Valve):In pneumatic jigs (air-pulsed), a valve controls the air injection. In mechanical jigs (ZONEDING specification), the eccentric mechanism controls the stroke.

How Does the Jigging Separator Machine Work?

The process is scientifically known as Hindered Settling.

• 1. Stratification:When the water pulses upward, the bed of ore lifts and expands. The particles separate from each other.When the water stops rising and starts to fall (suction), particles begin to settle.
• 2. Differential Acceleration:In the first instant of falling, heavy particles accelerate faster than light particles. This means gold/barite drops faster than silica.
• 3. Hindered Settling:As the particles crowd together, the smaller heavy particles sneak through the gaps between large light particles. This is called “trickling.”

The Result:After hundreds of pulses, the bed organizes itself into layers.

• Bottom Layer: Heavy Concentrate (Gold, Barite, Galena).
• Top Layer: Light Tailings (Sand, Silica, Shale).
  The machine then mechanically separates these layers. The tailings overflow a weir at the end, while the concentrate is discharged from the bottom.

4. The classifier adopts tile lining, with very low maintenance rate and higher durability of wearing parts.

What is the Price of the Jigging Separators? And its Affecting Factors?

Jigs are among the most affordable mining machines, but costs vary based on capacity.

• Price Range:
  • Small Laboratory Jig: $2,000 – $4,000 USD.
  • Standard Saw-tooth Wave Jig (JT1070/2): $6,000 – $12,000 USD.
  • Large Trapezoidal Jig (LTA1010/2): $15,000 – $25,000+ USD.
• Factors Affecting Price:
  • Capacity (Area): Jigs are sized by surface area. A 2 square meter jig costs more than a 1 square meter jig.
  • Waveform Technology: Older sine-wave mechanical jigs are cheaper. Modern hydraulic or saw-tooth wave jigs command a slight premium for their higher efficiency.
  • Materials: A jig used for diamonds might need secure locking mechanisms. A jig used for coal might need wear-resistant ceramic liners.

What Should You Consider Before Buying the Jigging Separators?

• 1. Water Supply:The Jig Machine is thirsty. It needs a constant supply of water to maintain the pulsation and to transport materials. Operations must have a water settling pond to recycle water; otherwise, the volume required is unsustainable.
• 2. Density Difference:The specific gravity difference between the mineral and the waste needs to be at least 1.25 for effective separation.
• 3. Test Work:Before ordering a 50-ton plant, send a sample to the ZONEDING laboratory. A “Washability Test” determines exactly how efficiently the material separates at different particle sizes.

Saw-tooth Wave vs. Sine Wave: Which Yields Higher Recovery Rates?

This is the most critical technical distinction in modern jigging.

The Old Way: Sine Wave Jigs
Traditional eccentric drives create a sine wave. The water pushes up and sucks down at the same speed.

• Problem: strong suction pulls everything down, including fine waste rock. This lowers the grade of the concentrate. It also compacts the bed too quickly, reducing the time available for stratification.

The ZONEDING Way: Saw-tooth Wave Jigs
The Saw-tooth Wave Jig uses a modified cam mechanism (or hydraulic drive).

• Action: The upward water stroke is fast (steep slope), lifting the bed quickly. The downward suction stroke is slow and long.
• Benefit: The bed stays “open” and loose for a longer time. This allows fine, heavy particles more time to settle into the concentrate layer without being sucked down by strong currents.
• Result: Recovery rates for fine minerals are improved by unprecedented margins, and water consumption is reduced by 30-40% compared to legacy sine wave jigs.

Jig Separator vs. Shaking Table: Which One Do You TRULY Need?

Customers often confuse these two gravity separators.

Feature	Jigging Separator	Shaking Table (6-S)
Capacity	High (Up to 100 TPH)	Low (0.5 – 1.5 TPH)
Feed Size	Coarse (2mm – 30mm)	Fine (0.074mm – 2mm)
Enrichment Ratio	Moderate (Roughing)	Extremely High (Cleaning)
Water Use	Moderate (Recyclable)	Low to Moderate
Footprint	Large Vertical Box	Large Horizontal Flat Shape
Best Role	Primary Concentration (Removing bulk waste)	Final Cleaning (Making saleable gold)

Wear Parts and Maintenance: How to Extend the Life of the Screen and Diaphragm?

Maintenance on a jig equals consistency in production.

• 1. The Rubber Diaphragm:
  • This rubber disc flexes thousands of times per hour. Over time, it fatigues and cracks.
  • Keep spare diaphragms on site. Inspect for micro-cracks monthly. ZONEDING uses high-grade industrial rubber designed for millions of cycles.
• 2. The Screen Mesh:
  • The abrasive ore constantly rubs against the screen. If a hole wears open, large rocks will fall into the concentrate hutch, ruining the product quality.
• 3. Artificial Bedding (Ragging):
  • For “through-the-screen” jigging, the operator places steel balls or ceramic stones on the screen. These act as a filter. If these balls wear down and become too small, the bed becomes too loose. Check and replenish bedding stones regularly.

Why is ZONEDING’s Trapezoidal Jig Design Superior for Large Capacities?

Standard jigs are rectangular. As the slurry flows from the feed end to the discharge end, the volume of material decreases (because the heavy stuff settles out).

• The Flow Velocity Problem:In a rectangular jig, as the material volume drops, the water flow speed drops. The slurry slows down at the end, causing the fine tailings to settle and contaminate the concentrate.
• The ZONEDING Trapezoidal Solution:The LTA Series Jig uses a Trapezoidal (tapered) shape. It is wide at the feed end and narrow at the discharge end.
  • Effect: As the ore volume decreases, the tank width decreases. This keeps the flow velocity constant coupled with the stratification.
  • Result: Significant improvement in treating large throughputs and fine materials simultaneously. It creates a uniform “separation intensity” across the entire length of the machine.
