Belt feeders are the type of feeders that perform only feeding function and specifically designed for handling at secondary and tertiary stages.
Driven by an electric motor and gearbox, head drum of feeder move the belt and transport material along the conveyor.
In addition to its different intended uses, it primarily regulates the capacity fluctuations that may occur at the primary stage by ensuring regular feeding of crushers at the secondary and tertiary stages.
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.
