今後望まれるところであった。However, a conventionally known pulverizing method and a pulverizing apparatus, for example, a method disclosed in
In the case of the crushing device disclosed in Japanese Patent No. 39648, the front edge of the support for feeding the waste material FRP to be crushed while mounted on a grindstone (referred to as a processing tool),
Since it is a structure that crushes waste FRP while simply approaching the cutting surface of the grindstone, it is impossible to crush all the waste particles to a uniform particle size, and it becomes a crushed residual piece such as a cut piece or a coarse crushed piece. And mixed into the regenerated powder ground to a uniform particle size. For this reason, conventionally, it is necessary to perform post-processing to remove the remaining crushed pieces mixed in the regenerated powder after the crushing process, and the time and labor required for the subsequent processing are immeasurable, which increases the processing cost. It is a fact that the cost increase is a major problem as a cause. However, the reuse of the crushed waste material FRP as a recycled powder resource is used, for example, by mixing it with cement-based inorganic material or recycling it to FRP, etc., but especially by mixing it with cement-based inorganic material. In the case of compounding or the like which is also reused together, if the particle size of the pulverized regenerated powder is not uniform, there is a possibility that the properties such as the original strength of the cement-based inorganic material are adversely affected. For this reason, the use of waste material FRP, which is discarded in a grinding process in which regenerated powder is not mixed with remnants and the like of which shapes and sizes are greatly different from each other as much as possible and in which the variation in particle size does not occur as much as possible, will be considered in the future. It was just what I wanted.

混ざることがない。Means for Achieving the Object In order to achieve the object, a technical measure taken by the present invention is to press a front edge of a guide base made of waste material FRP against a vertically rotating grindstone so that the front edge has an irregular shape on the surface of the grindstone. This is a grinding method in which the waste material FRP is fed along a guide base to a rotating grindstone and then plunge-ground while being pressed against the guide base after grinding to a suitable contact state. According to such a pulverizing method, when the waste material FRP is sent to a vertically rotating grindstone along the guide base and pressed, the waste material FRP is ground into a powder having a uniform particle size while being plunge-ground by the grindstone. At this time, the grinding powder of the waste material FRP plunge-ground by the grindstone, that is, the reclaimed powder passes through the fitting unevenness of the front edge of the guide base, which fits in contact along the uneven shape formed of the abrasive grains protruding from the grinding surface of the grindstone surface. Collected. Thereby,
Only the regenerated powder plunge-ground with a uniform particle size is collected. In addition, since the guide base is made of the same material as the waste material FRP to be pulverized, even if its front edge is ground by a grindstone, it does not become a foreign material of a different material and does not mix with the recovered recycled powder.

時に再利用される。In addition, a feed path for sequentially feeding a large number of waste materials FRP toward a grindstone rotating in a longitudinal direction is provided, and in the grinding process in which the last waste material FRP fed through the feed path is plunge-ground, the feed path is opened. This is a pulverization method in which a dummy FRP made of waste material FRP having substantially the same cross-sectional shape as the cross-sectional shape is fed so that plunge grinding of the last waste material FRP is completed. According to such a pulverizing method, a large number of waste materials FRP are fed through a feed path toward a grindstone that rotates vertically, and in the process of plunge grinding the finally sent waste material FRP, the waste material FRP is connected to the waste material FRP, and the same material is used. By sending the dummy FRP into the feed path, all the waste material FRP sent last can be sent to the grindstone, pressed, and crushed into powder by plunge cutting. At this time, the front end of the dummy FRP is ground into a cylindrical shape along the surface of the grindstone that rotates vertically, but is made of the same material as the waste material FRP. Absent. The dummy FRP whose front end has been ground into a cylindrical shape is reused at the time of the next pulverization processing of the waste material FRP.

A base feed mechanism that fixes and holds the guide base at the same position when the front edge of the guide base is ground, and a material automatic feed mechanism that feeds the waste material FRP toward the grindstone along the guide base. It is a crushing device provided. According to such a crusher,
The guide base made of waste material FRP is pressed by a base feed mechanism against a grindstone that rotates vertically until its front edge fits along the uneven shape of the grindstone surface, and the front edge is ground by the grindstone and protrudes from the grinding surface of the grindstone surface At the time when they are fitted and contacted along the uneven shape composed of the scattered abrasive grains, they are fixed and held at the same position by the base feed mechanism. In other words, the front edge of the guide base is kept in a state of being fitted and contacted along the uneven shape of the grindstone surface. Thereby, in a state where the plunge is not ground into a powder having a uniform particle size by the grindstone, for example, it does not pass between the guide base and the grindstone in a state of a crushed residual piece such as a cut piece or a coarse crushed piece. After being pulverized into a powder having a uniform particle size, the powder is recovered through the matching unevenness at the front edge of the guide base, which fits along the uneven shape of the grinding wheel surface. Then, the waste material FRP is pressed against the whetstone while being automatically fed toward the whetstone by the automatic material feeding mechanism, and is crushed by plunge grinding.

This is a crushing device provided with a guide base held by a base feeding mechanism along the bottom of the opening so as to be horizontally movable in the front-rear direction of the feeding path.
According to such a crushing device, the waste material FRP is pressed while being automatically fed to the grindstone by the material automatic feed mechanism as described above through the feed passage horizontally connected from the casing portion covering the grindstone, and is uniformly pressed by plunge cutting. It is pulverized into a powder. In the process of completing the plunge grinding of the finally sent waste material FRP, a dummy FRP made of the waste material FRP formed to have substantially the same cross-sectional shape as the opening cross-sectional area of the feed path.
Is fed into the feed path in tandem with the last waste material FRP, so that all the finally sent waste material FRP can be pulverized to be pulverized into powder having a uniform particle size.

The front end piece 3-10 alone can be appropriately replaced by being held by the fastening means. In other words, the front edge 3-1 of the grinding wheel 1 that is in contact with the grinding surface 1-1 along the uneven shape of the grinding surface 1 is pressed by the abrasive grains 1-10 of the grinding wheel 1 when the recycled powder M of the crushed waste material FRP4 is pressed by the abrasive grains 1-10. As it is rubbed and worn by the load action when it is scraped out to the 10 side, the guide base 3 is pressed against the grindstone 1 with the consumption and the front edge 3-1 is ground.
It is necessary to repeat the action of conforming to the uneven shape of 1-1. Then, the length of the front end piece 3-10 gradually decreases each time the above-mentioned action is performed, and the length is longer than the range of the pressing force applied to the grindstone 1 by the base feeding mechanism 5 (the moving distance of the slide portion 5-1). Only the front end piece 3-10 that separates when it becomes shorter can be replaced as appropriate. Further, the base width of the guide base 3 may be narrower than the width of the grindstone 1 so that the grinding process of the waste material FRP4 by plunge grinding is surely performed.
