Single Plunger Jig

DESCRIPTION

The Single-Cell Plunger Jig is a compact, laboratory-scale gravity separation device designed for density-based concentration of mineral particles. Built around a single separation cell driven by a plunger-type pulsation mechanism, it delivers consistent, reproducible results for ore characterisation and benchtop concentration studies.

Features:

  • Plunger Mechanism (Fixed Stroke): A 20 mm fixed-stroke eccentric plunger generates the up-and-down water pulsation that drives stratification, ensuring stable and repeatable separation.
  • Adjustable Pulsation Rate: Continuously variable from 0 to 300 RPM via an electronic motor speed controller, allowing fine tuning for different ore types and particle sizes.
  • Plunger Assembly: Single 75 × 100 mm plunger, sized for laboratory throughput.
  • Stainless Steel Construction: All wetted parts are manufactured from polished AISI 304 stainless steel for corrosion resistance and long service life.
  • Nominal Capacity: Approximately 5 kg/hour, depending on feed type and granulometry.
  • Mobile Frame: Steel frame with six storage shelves and a top working surface, supported by four lockable swivel casters for easy repositioning in the lab.

The Single-Cell Plunger Jig is ideal for benchtop testing of gravity-concentratable ores, offering the precision and flexibility required for mineral processing research and pre-feasibility assessments.

Working Principle

Plunger jigs separate mineral particles based on differences in density. A reciprocating plunger generates an up-and-down pulsation in a water-filled cell, fluidising the particle bed and allowing denser minerals to settle through lighter ones.

  1. Pulp Preparation: A water-and-solids slurry of controlled density is fed to the jig.
  2. Pulsation Motion: The reciprocating plunger generates rhythmic vertical water motion within the cell.
  3. Density-Based Separation: Heavier particles settle through the bed while lighter ones rise, producing distinct density layers.
  4. Layered Stratification: The bed organises into a heavy concentrate layer at the bottom and a lighter tailings layer above.
  5. Product Collection: Concentrate and tailings are discharged separately through the bottom and overflow outlets.

Plunger jigs are widely used in mineral concentration, coal washing, and other gravity-based separation applications. Their mechanical simplicity, low operating cost, and high efficiency make them a benchmark tool in mineral processing laboratories.
