Jig Mineral Processing

Three Piston Jig

DESCRIPTION

The Three-Piston Jig is a high-capacity machine used in laboratories to evaluate the separation potential of various materials based on density differences. This jig enables efficient material separation, particularly useful in mineral processing applications, to achieve precise results.

Features:

  • Adjustable Pulsation Rate: The pulsation rate can be continuously adjusted between 0-300 RPM, allowing precise control tailored to different material types and processing needs.
  • Piston Compartments: The jig includes three piston compartments, each measuring 200 x 275 mm.
  • Screens: Equipped with bottom screens of 1 mm, 2 mm, 3 mm, and 4 mm apertures.
  • Steel Frame Construction: Built with three 200 x 275 mm cells in a robust steel frame, the construction enhances durability and longevity, ensuring reliable performance.
  • Eccentric Shaft and Bearings: The pulsation shaft’s rotation rate is adjustable between 0 – 300 RPM via an electronic motor control. Durable bronze bearings support the eccentric shaft, providing a long-lasting and efficient operation.
  • Independent Valve Control: Each cell is equipped with individual bottom valves and independent top water supply valves, providing flexibility and control throughout the process.
  • Nominal Capacity: The device has a nominal capacity of up to 15 kg/hour, with actual throughput depending on the type and size of processed materials.

The Three-Piston Jig is optimized for density-based material separation in laboratory environments, offering high performance and precise control, particularly for evaluating mineral processing and concentration potential.

Working Principle

Jigs are mechanical machines used in density-based separation processes, commonly employed in mineral processing and material concentration applications. Their primary function is to separate heavy and light particles, allowing for effective concentration of valuable particles based on their density.

  1. Pulp Preparation: The jig is fed with a pulp, a mixture of material particles and water adjusted to a specific density. This pulp forms the basis of the separation process and is typically stored in a feed tank.
  2. Pulsation Motion: The jig operates with an up-and-down pulsation motion, generated by a piston or diaphragm. This motion moves the water and suspended particles within the jig, creating a fluid environment for separation.
  3. Density-Based Separation: During pulsation, heavier particles, such as valuable minerals, settle quickly toward the bottom of the jig due to their higher density, while lighter particles rise toward the surface. As a result, the heavy materials concentrate in the lower layer, and lighter particles remain in the upper layer.
  4. Layered Particle Separation: This density-based stratification within the jig creates distinct layers of materials. High-density particles, like metal ores, accumulate in the lower layer, while lighter particles, often considered gangue minerals, collect in the upper layer.
  5. Material Collection: Once the separation process is complete, heavy and light materials are collected separately. This step is critical for achieving high concentration and purity of valuable minerals.

Jigs are widely used in mineral concentration, coal washing, and other industrial separation processes. Their simple mechanical design, high efficiency, and low energy consumption make jigs an ideal choice for various industrial applications, offering an effective solution for density-based material separation.
