Jigs

Classify with absolute selectivity

The precise jigs programme

Modern processing plants must fulfil the increasing demands on raw material quality and the need to reuse primary or secondary raw materials. In addition to the selection of suitable components for sorting, new machines for classification ensure technical and therefore also economic success. If the materials responsible for the contamination have lower densities compared to the saleable raw material, sorting by density is a good option.

For this reason, STICHWEH jigs are being used in more and more processing operations. STICHWEH jigs are built in co-operation with our partner, Snoby Separation Systems LLC, in Thüste.

Select a perfect fit

Efficient separation

Jigs separate according to the decisive characteristic "density". STICHWEH jigs impress with their high throughput - up to 270 tonnes per hour - and the use of precise operating data to select the process and predict the raw material quality. Thanks to the automatic discharge control with analogue layer height measurement during operation, the STICHWEH jigs offer excellent results of the materials for further industrial use.

From sorting to discharge

To remove the light material (bad material, e.g. coal, shale, iron oxide, pumice, shells ...), the material is placed on the jigs. A pulsed stream of water lifts the material and arranges it according to its density. The material layer is put into a loose, fluidised bed-like state by the pulsating upward flow of water. The light material sinks much more slowly than the heavy material and so a layer formation takes place according to the density - i.e. the light material comes to the surface of the material bed, the heavy material collects in the lower part.

The separation of the light material takes place in the upper area. The heavy material is discharged below the light material. Various discharge options are available depending on the grain size.

Jigs in use

When using STICHWEH jigs, the following requirements are met:
The normal sorting process remains simple, economical and ecologically efficient.

The selected sorting process

  • enables a high degree of selectivity
  • over the widest possible grain size range
  • via a widely adjustable separation density

The integration of the sorting system ensures maximum operational reliability and a smooth process.

It functions

  • with minimal personnel, energy and wear costs
  • and settings customised to the site and raw material conditions

Selectivity - even better classification results
