Apron feeder operates by using a series of overlapping metal plates (aprons) mounted on heavy-duty chains. These chains are driven by sprockets connected to a motor, which moves the plates forward. As the plates move, they carry large, heavy, or abrasive materials from a hopper or storage bin to downstream equipment, such as crushers or screens. The apron feeder ensures a continuous and controlled flow of materials, making it ideal for handling tough and bulky loads in industries like mining, cement, and metallurgy.
