Belt Feeders

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.

Apron feeders come in varying widths, ranging from 0.6 to 3.0 meters, and lengths spanning from 2.4 to 30.5 meters. Lengths exceeding 4.6 meters are primarily used for material conveyance rather than being an integral part of the feeder. Apron feeders exhibit capacities ranging from 91 to 2,270 tons per hour. The power requirements for apron feeders are approximately twice as high as those for comparable belt feeders. Apron feeders are typically employed in situations involving truck dumps or other scenarios where very coarse materials are handled, such as in the feeding of primary or secondary crushers. When an apron feeder is intended for use under a truck dump hopper with an elongated hopper opening, it’s essential to design the hopper with a taper that widens in the direction of horizontal flow for belt feeders.

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.

Various minerals are found in nature either in a dispersed state, where they exist as separate entities, such as native gold particles in silica rock, or in a combined form, where they are bound within a host rock. Dry material separations using screens and sieves are typically attempted down to particle sizes of about 75 microns. Finer materials have a tendency to block the sieve openings. In such cases, screening in the presence of water can be helpful. Separating even finer-sized materials becomes challenging using traditional sieves. For such fine materials, alternative processes like classification need to be employed.
