Jigs – Wet Process

alljig® uses a wet process to efficiently upgrade materials of different density

Jigging is a process that involves initial differential acceleration, hindered settling and consolidation trickling. The separation of minerals in the jigging process is based on the principle that particles will stratify in pulsating water.

The upward and downward currents fluidize and compact the grains into relatively homogenous layers. Low density particles stratify on the surface, while the heavier particles settle in the lower level of the bed.

alljig® units are available as side-pulsed and underbed-pulsed jigs that are suitable for a wide variety of materials with varying feed sizes and capacities.

Applications

Iron ore and other metallic minerals
Coal
Gravel and sand
Recycling industrial and building materials
Industrial minerals
Metalliferous slag
Separate organic matter e.g. wood and coal
Purifying contaminated soil

Features

Available as side-pulsed or underbed-pulsed jigs
Robust construction
Processes wide range of particle size from 150mm to less than 1mm diameter
High tonnage capability per meter width – up to 100 TPH/metre width depending on application
Machines use an air pulsed to create water movement that has low abrasion in the jigs
Adjustable stroke-motion (frequency, amplitude and shape) allowing optimum settings
Discharge of products are by continuous bleed discharge method which is application specific
Analogue measurement system for stratification and discharge control allows simple and exact detection of gravity horizons and continuous bleed discharge
