Referring to FIG. 2, the conventional apparatus for cutting foreign materials is provided in front of the continuous cutting apparatus 12, A plurality of great bars 30 spaced apart from each other by a predetermined distance while being inclined downward are provided at a point where they drop from the transfer conveyor 13 to the transfer conveyor 13. Thus, the raw material passes through the gap between the grooved bars 30 and falls into the conveying conveyor 13, and the foreign substances which can not pass through the gap of the grooved bar 30 are moved forward by the grooved bar 30 and collected.

However, this means that as the working time increases, adhered light is generated in the griddle bar 30, and thus the raw material is not smoothly supplied to the conveying conveyor 13, thereby causing a reduction in the operation rate of the sintered light production line.

In addition, since the foreign matter collected and separated by the great bar 30 has to be transferred directly to a separate place, there has been a problem of increasing the labor intensity of the worker.

Therefore, conventionally, a technique of separating foreign matter mixed in a raw material with a rotating foreign object removing rod has been proposed and used. The related art is described in "Formulation Foreign Material Removal Apparatus (Patent Document 1: Registration Practical Utility Model No. 20-0150190)" Are specifically known.

However, in Patent Document 1, since the foreign object removing rod is rotated at a constant speed, there is still a problem in that adhered light is generated in the foreign object removing rod and the bearing water as the working time is increased.

In addition, although the foreign matter separated by the foreign object removing rods is collected in the foreign object collecting box, the worker has to empty the foreign object collecting box by moving the foreign object collecting box directly.
