Hereinafter, the recycling process of titanium using the high purity titanium recycling apparatus according to the above-described embodiment of the present invention will be described in more detail.

When power is supplied to the high-purity titanium recycling apparatus, the operation of the cutting unit 100, the operation of the conveying conveyor 200, the operation of the driving motor 311 constituting the crushing unit 300, 340, the operation of the carry-out conveyor 400, and the operation of the sorting and discharging unit 500 are performed.

In this state, the operator cuts the titanium waste to be reproduced by using the cut-off portion 100 to a size capable of crushing operation, and provides the cut titanium to the conveying conveyor 200. Of course, the operation of supplying the titanium cut in the cutting part 100 to the conveying conveyor 200 can be automatically performed by the conveying conveyor 200 (see FIG. 1) by improving the arrangement structure with respect to the part where titanium is discharged from the cut part 100, ). ≪ / RTI >

Thus, the titanium is gradually transported upward by the transporting conveyor 200, falls freely at the end of the transporting conveyor 200, and is introduced into the crushing section 300.

The titanium inserted into the crushing unit 300 is supplied to a portion where each of the drum type cutters 310 is installed through the portion where the blocking plates 330 are installed in the crushing unit 300, (Approximately 3 cm or less in width) in the process of passing between the cutters 310.

At this time, when the above-mentioned titanium is crushed, the fragments of the titanium are scattered irregularly. However, by the blocking plates 330 disposed in an intersecting structure in the upper chamber of each of the drum-shaped cutters 310, And is discharged to the outside by the cover body 320 which closes the open top surface of the crushing part 300 even if some titanium fragments bulge into the space above the crushing part 300 .

At this time, smoke and heat generated in the space inside the crushing unit 300 are continuously discharged by the operation of the blowing fan 340, whereby the titanium is prevented from being oxidized at a high temperature due to the high-temperature heat, It is possible to prevent the deformation of the properties of the titanium and to obtain titanium of high purity.

The titanium scrap that has been crushed while being passed through the crushing unit 300 as described above is dropped by its own weight and is provided as a carry-out conveyor 400 positioned directly below the crushing unit 300, And is carried out into the drum body 520 constituting the sorting discharge unit 500.
