骨材９としてタンク８内に貯蔵される。In order to produce the artificial aggregate of the present invention using the apparatus having the structure shown in FIG. 1, first, waste plastic such as plastic bottles is dissolved in a melting tank 1 by a heating device (not shown).
Heat and melt at 00 to 400 ° C to obtain a waste plastic melt. During this dissolution, the melt is stirred by the stirrer 2 to obtain a more uniform melt. Next, the obtained melt is supplied to the mixing / pressure vessel 3 through the pipe 6 under the adjustment of the valve 7. The supplied melt is mixed in a mixing / pressure tank 3
Immediately in it is mixed with sludge dust to form a clay-like material having a temperature of around 200 ° C. During this mixing, the clay-like material is stirred by the stirrer 5 to achieve more uniform mixing. The clay-like material is extruded from the base 4 by its own weight or by a pressure from a pressure device (not shown). The noodle-shaped clay-like material extruded from the viscosity adjusting hole 11 of the base 4 is cut into an appropriate particle size by its own weight, or after being adjusted to a predetermined particle size by a particle size adjuster (not shown), is cooled with water or air. . Then, it is finally stored in the tank 8 as artificial aggregate 9 having a predetermined particle size.

Here, when the amount of sludge dust is less than 50 parts by weight, the amount of sludge dust used is small, and the effect of recycling industrial waste is reduced. When the amount of sludge dust exceeds 300 parts by weight, as an artificial aggregate, May not be obtained. In addition, the optimal mixing ratio varies greatly depending on the type of dust, but depending on the purpose of use of the aggregate, it can be from light to heavy, from small to large in particle size, or from large to small in aggregate strength. , Can be freely mixed and adjusted.

Since the sludge dust is solidified and confined in polyethylene terephthalate molecules, a safe artificial aggregate can be manufactured. Moreover, the artificial aggregate manufactured by the present invention is mainly used as an aggregate of concrete. Therefore, even if some harmful substances remain in the artificial aggregate, the industrial living waste can be recycled in a safe form by obtaining the structure by confining it in concrete.

On the other hand, when it is desired to obtain an artificial aggregate having a particle size of less than 5 mm, it is preferable to manufacture as follows. That is, in the apparatus shown in FIG. 1, a melt is obtained by heating and dissolving waste plastic using a mixing tank 3 having no base 4 at the bottom, and a predetermined amount of sludge dust is mixed with the obtained melt, and high-speed mixing is performed. By cooling with water or air after stirring, an artificial aggregate can be easily produced. The materials of the waste plastic and the sludge dust, and the mixing ratio of the waste plastic and the sludge dust are the same as those in the above-described embodiment.
