Abstract: A modular pulley assembly for a continuous belt conveyor can be assembly from a plurality of modular pulley disks that can be axially aligned and abut against each other to provide pulleys of differing lengths per demand. The modular pulley disks can be made from a non-metallic material such as a polymer and can manufactured by a suitable molding process. Making the modular pulley disks from non-metallic materials enables the disks to be formed with structural geometries such that the assembled pulley is structurally more rigid and can better distribute torsional loads and momentum from the belt to the support shaft.
