What is a Belt Feeder?

Belt feeders are specially designed with short belts and low speed conveyors. They are generally used for feeding ground and fine materials and in dosing units.

The conveying and return rollers of the feeder conveyor are flat, and conveyor rolls are close together. The rollers ensure a smooth feeding of material as they are manufactured to suit length and width of the belt. Electric motors and reducer are commonly used for the drive system. In light working conditions the belt can also be rotated using a belt pulley system.

Feeders are produced depending on the material type, the necessary capacity and the loading conditions. Although belt feeders are short, the belt may be up to 4 meters wide in some applications. For example, belt feeders of up to 4 meters in width are used for feeding grates for heat treatment in iron ore pellet plants.

For what processes/applications are belt feeders used?

Belt feeders are used to feed smoothly flowing materials with a maximum size of 120 mm. They can be used to feed vibrating screens, secondary or tertiary crushers and conventional transport conveyors that require a regular and continuous feed. They are generally mounted horizontally. The end of the belt is located under a bunker or stock chute. Thus, as the material is emptied through the rotation of the belt, the material must be supplied from the bunker above in a continuous flow, without the need for intervention. A vibration motor can be connected to the bunker to prevent blockages in the feeding bunker.

In belt feeders, the rotation speed of the belt is adjusted by means of a power and reducer connection, and the desired feed capacity can be ensured by adjusting the speed. Most of the time, the motion system of the belt feeder is connected to the belt scale on the belt conveyor to which the material is conveyed after the feeder.

Belt feeders are widely used in power plants for feeding coal and ore preparation and enrichment and aggregate production plants, in agriculture, and in any industry where the regular and controlled feed of material below a certain size is required.

What materials are suitable for belt feeders?

Belt feeders are generally to convey coal in coal mines and power plants, ore in enrichment plants and sand in the construction sector. Belt feeders are often preferred for the smooth, continuous and cost-effective feed of the finely ground dry or slightly moist porous materials that are common in mining, especially if they need to be conveyed by another long belt.

Belt feeders are also used in dosing systems. This feeder is also used for feeding the materials required for the continuous or intermittent mixing of different materials in the desired ratio or quantity by adjusting the feeder speed under bunkers containing different materials.
