The driver for the feeder, also known as a crosspiece, is a component of Domer feeders designed to drive gear rings in fuel feeding systems intended for burning coal dust. The driver is mounted on the screw shaft in the air chamber behind the combustion chamber. Through rotational movement, the blades of the driver cause the gear ring, which is an internal element of the retort furnace, to rotate. The rotation of the ring causes the breaking of clinkers formed as a result of coal dust combustion. This element is made of steel and has appropriate dimensions for specific types of feeders. It is mounted on the screw using a sleeve of specified dimensions, which is part of it. The Domer feeder driver is an original spare part and ensures the proper operation of the fuel feeding system.
