Abstract

The present invention relates to blasting material and production method and device for the blasting material, in which a resin matrix is blended with a conductive fiber, powder or particulate consisting of metal, metal oxide and iron oxide to form the blasting material. The blasting material is formed with irregular polyhedral tiny particles and the grain sizes is made homogeneous in each classification phase so as to be suitable for grinding, cutting and separating. The production device for the blasting material comprises crusher units (11), which crusher units (11) being for roughly crushing platy moldings of resin matrix into a dice- or pellet-form and a roll-type coarse crushing unit (15) and a crushing unit (16). The crushing unit (16) comprises multi-stage crushing rolls (31-33) in which irregularities (36) formed on the surfaces of each pair of facing rolls are phase-deviated at 1/2 of a pitch and which crushes coarsely-crushed resin pieces into specified sizes. Classifying devices disposed downstream the crushing unit (16) classify the resultant resin pieces to provide blasting material which is homogenized according to classification and which consist of polyhedral tiny elements having sharp ridges. By setting the spacing between irregularities on the crushing rollers and the gap between opposing rollers to the optimum condition, it is easy to change and modify the grain size of the blasting material. By homogenizing the grain size of the blasting material, the separating capability of the blasting material is enhanced and the operation time required for separation is shortened.

The mixture of projection materials and dust entering from the entrance of a person is collided and spread quite fiercely at a high speed, and is scattered to the inner wall of the separation container, the inner lid, and the uppermost diffusion plate. At this time, the dust is blown out from the first discharge port 46 ', so that the dust passes through the space between the outer surface of the separation container and the back surface of the storage container cover, reaches the discharge port 46, and is attracted to Dust collector 29 (Figure 2). [Structure and Function of Diffusion Plate] Next, the recyclable granules with a large mass and the dust that is not released from the fourth outlet port 46 are passed through each of the diffusion plate (not shown). The tooth holes or gaps in the i 'fall on the diffusion plate, and impact and diffuse the soil diffusion plate. Here, once again, the small knife dust of a small mass is lifted up so that the dust passes through the perforations or slits of the diffusion plate so that the dust can be discharged from the first discharge port 46. After the operation as described above, in the end, the recyclable granules and a small amount of residual dust that passed through the diffusion plate fall below the funnel groove. However, at this time, the second outlet 47 , Blow out the dust of small mass, so that the dust passes through the space between the outer wall and the inside of the separation container 28, so that the dust is discharged from the dust discharge port. ;] ——The recycling of the projection material during sandblasting is carried out by spraying the object to the object to crush the projection material and reduce it ^. And the sharp ridgeline part is rounded, and then , Using the ^ separation device to screen the projection material, in order to repeatedly repeat: divide the projection material. Even if the particle size of the projection material is reduced, the use of it will change
