In this process, a phenomenon in which fine powder (coal powder), which is a foreign matter (D), accumulates in the inner ring 232 of the mini riser 230 is fixed and fixed in the mini riser 230. In this case, the lead 240 on the mini-rising pipe 230 is lifted due to the adhered foreign matter D, which interferes with the mechanical parts during the movement of the raw coal charging vehicle 250, which leads to the collision of the device. As such, it is important that the height of the lead 240 is not increased by removing the foreign matter D fixed to the inner ring 232.
