What is jig machine?

JIGS. It is a work holding device that holds, supports and locates the workpiece and guides the cutting tool for a specific operation. Jigs are usually fitted with hardened steel bushings for guiding or other cutting tools. a jig is a type of tool used to control the location and/or motion of another tool.

What is jig process?

Jigging is the process of particle stratification due to alternate expansion and compaction of a bed of particles by a vertical pulsating fluid flow. A single jigging vessel can treat large particles (up to 200 mm) at capacities approaching 680 tonnes (750 tons) per hour.

How does a mining jig work?

With mineral jigs the process is accomplished by flowing a stream of liquid-suspended material over a screen and subjecting the screen to a vertical hydraulic pulsation. This pulsation momentarily expands or dilates the screen bed and allows the heavier materials to work toward the bottom.

How does a gold jig work?

The mineral bed is repeatedly moved up by the water, expands, and then re-settles, the resettlement occurring with the water flowing down at a lower rate (because of the addition of hutch water) than that which occurred on the upstroke. …

What are the advantages of using a jig?

Advantages of Jigs and Fixtures

• Increase in production.
• The consistent quality of manufactured products due to low variability in dimension.
• Cost reduction.
• Inter-changeability and high accuracy of parts.
• Inspection and quality control expenses are significantly reduced.

What is the working principle of Jig Boring Machine?

Jig boring machine works on the principle of feed in the vertical axis of the hole and its radius. In this process rotating tool is moved over the process is given with respect to static work. This principle is used for large workpieces.

What is a jig in mining?

Jig concentrators are devices used mainly in the mining industry for mineral processing, to separate particles within the ore body, based on their specific gravity (relative density). The particles would usually be of a similar size, often crushed and screened prior to being fed over the jig bed.

What technique is used in jigging process?

In the process called jigging, a water stream is pulsed, or moved by pistons upward and downward, through the material bed. Under the influence of this oscillating motion, the bed is separated into layers of different densities, the heaviest concentrate forming the lowest layer and the lightest product the…

How does a jig concentrator work?

【Jig concentrator working principle】 The mixture of mineral particles of different specific gravities is layered by specific gravity in a vertically moving variable-speed medium flow (water or air). High stroke and small times better for coarse material, low stroke and high times for fine particle size.

What is Baum jig used for?

A Baum Jig for gravitational enrichment of minerals, particularly hard co in which a screen deck is transversely located to the axis of the jig. Air chambers are made of plates as cut-outs of a cylindrical surface.

How do spirals work?

How exactly do they work? Slurry is pumped to the upper part of the spiral, which is usually 13′ to 15′ from the floor. From there, it enters a feed distributor, which evenly distributes the feed to each spiral concentrator. Gravity, along with the specific design and shape of the spiral, are the key to making it work.
