The alljig® jig enables efficient wet processing and density-based separation of a wide range of primary and secondary raw and waste materials with varying densities. By combining water and air pulsation, the system ensures reliable, cost-efficient, and stable operation.

  • Precise automatic discharge control for consistently high product quality
  • Flexible configurations for one to four separation stages within a single unit
  • Twelve different machine widths for various feed capacities
  • Extensive adjustment options to optimize the sorting process, even during operation

Wet processing and density-based separation with alljig® jigs

The alljig® jigs enable efficient wet processing and density-based separation of mineral raw materials. The air-pulsed technology allows water pulsation to be generated with minimal wear and flexibly adjusted to different materials, ensuring stable, cost-efficient, and reliable processing conditions.

A key element of the process is the precise separation of heavy material from the stratified bed. This is achieved through a controlled discharge system monitored by a float-based mechanism. Electronic sensors continuously detect the separation layer, enabling automatic adjustment to changing material conditions and ensuring high process stability as well as consistent product quality.

Depending on the raw material and particle size, different discharge systems are used to ensure optimal adaptation to the process. These include screen discharge systems for fine materials, sliding gates or movable beds for flexible applications, and rotary valves for controlled material flow.

Reference projects

High-quality gravel with alljig®

Kieswerke Ohle & Lau GmbH, located in the south-east of Schleswig-Holstein, Germany, is one of allmineral’s longest-serving customers. For more than 25 years, an air-pulsed alljig® gravel jig has been deployed here to ensure reliable and efficient processing of this raw material for the creation of maximum-purity gravel. Capable of extremely precise adjustment, this jig is guaranteed to separate out any components that react with alkalis.

Bituminous coal processing with alljig®

Since 2018, two powerful alljig® jigs at the Uvalnaya mine in Siberia have handled the processing of high-quality bituminous coal to generate products for the global market. High-quality coke is enjoying increased demand in the context of pig iron production at integrated smelting works. 

Ore mining with alljig®

In the south-east of Australia, alljig® jigs boasting low energy and investment costs are hard at work processing iron ore. This innovative system, which was adapted to suit the new conditions at the Iron Baron Mine, represents a major triumph for allmineral and SIMEC Mining alike.
