Therefore, after wastes of these glass fiber-containing plastic products are finely pulverized by a cutter type pulverizer composed of a rotary blade and a fixed blade (for example, a pulverizer disclosed in Japanese Patent Publication No. 47-18819). Attempts have been made to throw the finely pulverized material into a sorting machine 100 as shown in FIG. 5 to sort and collect only plastic. That is, this sorter 100 is configured such that the finely pulverized product is fed to the first sort tank 101
The air from the blower 102 to the first separation tank 10
1 is blown into 1 to form an air flow in the first sorting tank 101 to blow up the glass fiber, which is a light weight component in the finely pulverized material, to the upper side of the first sorting tank 101, and from a suction port 103 leading to a dust collector. Aspirate the glass fibers. And the first

However, the wastes of plastic products containing glass fibers, if not sufficiently pulverized, remain in a sandwich state in the pulverized plastic products, and the glass fibers are completely removed from the pulverized plastic products. It is impossible to separate. On the other hand, if the waste of the plastic product containing glass fiber is crushed with the above cutter type crusher until the plastic is sufficiently fine, the glass fiber and the plastic are completely separated. When it is rotated at a high speed, it contacts the cutting blade and is crushed, so if it is crushed too much, the plastic component will be burned and the color tone will change. Therefore, there is a problem in that it cannot be used when molding a product that requires decorativeness.

Further, in the case where the sorting process is performed by the sorting machine 100, pill-like fibers are produced during the sorting process, and the sorting is required again, and there is a problem that the recovery rate is poor. Further, due to friction during pulverization, the plastic is charged (-) and the glass fiber is charged (+).
Even if the plastic is burnt and can be finely crushed and separated from the glass fiber without changing the color tone, there is also a problem that the plastic and the glass fiber are re-attached due to the electric suction force, and it is difficult to separate and collect them.

The finely pulverized product thus obtained is introduced into a vibrating screener in the first fractional recovery step, and is separated into a glass fiber component which does not pass through the sieve and a primary fractionated product which passes through the sieve. That is, most of the glass fibers are separated and removed in the primary separation and collection process. On the other hand, the primary separated products that have been separated and collected in the first separated collection process are put into a vibration feeder that is a second separated collection process. In the vibrating feeder, the primary separated product put into one end of the diaphragm vibrates and is dispersed by the diaphragm and moves toward the other end. The light weight in the primary separation product, that is, the glass fiber component is separated and blown up by the wind supplied from the blower installed on the side of the dust collector, and the blown glass fiber component is passed through the duct connected to the dust collector.

A fine pulverizer for fine pulverization, and a vibrating screener for separating the fine pulverized product obtained by the fine pulverizer into a sieve non-passing component containing most of the glass fibers and a primary fractionated product passing through the sieve, While moving the primary sorted product charged to one end in the direction of the other end by vibration, a diaphragm provided with a wire mesh portion in the middle portion, and provided below the wire mesh portion of this diaphragm, over the wire mesh, By blowing wind to the primary separated product passing through the wire mesh part and blowing up the light weight component in the primary separated product, a vibrating feeder consisting of a blower and the primary separated product put in the vibrating feeder are corona-discharged. A static neutralization blower that removes the static electricity charged in the glass fiber component and the finely pulverized plastic material in the primary separation product by blowing ionized wind, and a dust collector that sucks and collects the light weight component blown up by the wire mesh portion of the vibrating feeder. A vertical passage through which the secondary separated product excluding the light weight component passes from the primary separated product discharged from the other end of the vibrating feeder, and the fine particles remaining in the secondary separated product on one side wall surface of the passage. There is a wire mesh of a size that allows the glass fibers to pass but does not allow the finely pulverized plastic to pass, and passes through the wire net while diffusing the secondary separated product with the airflow generated from the wire net side toward the wire net by suction. A recovery device that removes the fine glass fibers in the secondary fractionated product and collects the finely crushed plastic that does not pass through the wire net by dropping it to the lower side of the passage. Plastic content of the separation and collection equipment from fiber-filled reinforced plastic products.
