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.

A belt feeder is comprised of an uninterrupted rubber belt that is supported by closely spaced idlers and propelled by end pulleys, commonly known as the head and tail pulleys. This entire assembly is enclosed within a single framework. The motor can be installed on the ground or on a separate frame and drive the feeder through the use of V-belts. Typically, the belt feeder is positioned beneath a hopper with a long, narrow slot-like opening. It allows the material to be fed along the length of the hopper. Belt feeders typically come in a range of widths from 0.6 to 1.8 meters and lengths spanning from 1.5 to 4.6 meters. The capacity of a belt feeder is determined by the width of the belt and the speed at which it moves. In practice, the capacity of belt feeders generally falls within the range of 4.5 to 2,270 tons per hour. Novelty Structures supplies various type of Feeders for Mineral Processing Plants.

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.
