The distinctions among various jig types is related to the methods employed for generating pulsation and the manner in which the heavy fraction is extracted from the jig. The screen’s role is to provide support to the particle bed, and the space beneath it is referred to as the hutch. Typically, the tank is divided into two primary sections: one housing the support screen with the ore bed and another responsible for generating the fluid flow. The heavy discharge from the jig can exit in two ways: either passing through the screen or flowing over the screen. When employing jigging through the screen, every particle in the input is smaller than the screen openings, allowing them to potentially fall through the screen and gather in the hutch. Novelty Structures supplies Mining Jigs for various materials.

A screw feeder is primarily designed for handling very low-tonnage outputs, with a critical requirement for positive and controlled material discharge. This type of feeder offers the advantage of easy enclosure, making it effective at preventing the release of dust. Consequently, it allows for a sealed hopper and chute arrangement from the hopper to the delivery point. The basic structure of a screw feeder includes a helical screw that rotates below the hopper outlet and is driven by an external power source. The screw can have a fixed pitch or a variable pitch with smaller spacings in the rear and gradual increases in pitch towards the discharge end. This design ensures that the material moves efficiently within the rear portion of the hopper. Novelty Structures supplies various type of Feeders for Mineral Processing Plants. * Belt Feeders * Screw Feeders * Apron Feeders * Rotary Table Feeders
