In the case of this cyclone 7, relatively heavy crushed materials fall due to the vortex flow generated by the cylindrical body, and are directly supplied to the volume reduction machine 8 from the bottom opening under wind pressure, while light dust is transferred to the exhaust stream.

添加しない乾式成形で行われるものである。この
乾式成形においては、成形直前に粒子を粉砕して
清浄な破面を作り、その直後に成形すれば、さら
に強い結合力をもつ成形物が得られる。 In general, cohesive force is required to solidify powder and granules, and the factors involved in bonding powders are (a) cohesive force of the powder itself, and (b) bonding due to capillary filling of liquid. There are methods such as force (c) sintering or melting (d) bonding by charging, but in the volume reduction treatment method described above,
Mainly, the binding force of the powder itself is used, and dry molding is performed without adding a solidifying agent. In this dry molding, if the particles are pulverized to create a clean fracture surface immediately before molding, and then molded immediately thereafter, a molded product with even stronger bonding strength can be obtained.

210Kgｆ／cm2の範囲で固化することが確かめられ
ている。加圧力をそれ以上に高くしても、密度の
増加は少なく、飽和状態に近くなる。 Furthermore, it is known that bonding force is involved in the contact area between particles, and it is necessary to apply a compressive force of a certain value or more in order to increase the contact area. In that case, the compression force required for molding and solidification differs depending on the material, but for the waste materials mentioned above, the compression force is 140Kgf/cm 2 ~
It has been confirmed that solidification occurs within the range of 210Kgf/cm 2 . Even if the pressing force is increased beyond that, the density will not increase much and will be close to a saturated state.
また、前記廃材類の粉砕にあたつては、粒度３
mm以下、または繊維長15mm以下に粉砕したものが
最も好ましく、それ以上のものは完全固化が難し
くなる。 In addition, when crushing the waste materials mentioned above, the particle size is 3.
It is most preferable to crush the fiber to a particle size of 15 mm or less, or a fiber length of 15 mm or less; anything larger than this makes it difficult to solidify completely.

つて減容固化可能であるが、ロツクウール保温材

難く、微細な繊維になるため、圧縮しても乾燥状
態では固化しない。 Among the waste materials mentioned above, calcium silicate insulation materials and urethane foam cold insulation materials can be reduced in volume and solidified by the treatment method described above, but rock wool insulation materials are fibrous and cannot be crushed into powder even when crushed. Because it does not easily break up and becomes fine fibers, it does not solidify in dry conditions even when compressed.

ことが実験により確かめられている。 However, if you mix pulverized rock wool insulation material with pulverized calcium silicate insulation material, which can be reduced in volume and solidify, at a weight ratio of 50% or more and compress it, it can be solidified by the binding force of the calcium silicate powder. It has been confirmed through experiments that

かめられている。 The glass filter material in the waste material is also fibrous, and when it is new before being used as a filter material, it will not harden even when crushed and compressed, just like rock wool insulation material, but after use, it will not solidify even if it is crushed and compressed. It has been confirmed through experiments that a compressive force of 140 Kgf/cm 2 or more can reduce the volume and solidify because the binding force is added due to the intervening ducts etc. where the material is collected and attached.

形物が得られる。 According to the volume reduction treatment apparatus shown in Fig. 1, among the waste materials mentioned above, calcium silicate heat insulating material, urethane foam cold insulating material, and glass filter material are processed separately through the crushing, crushing, and compression processes. Then,
A compression molded product whose volume is reduced and solidified to a volume reduction rate of about 1/3 to 1/15 is obtained.

供給される。 As described above, the rock wool insulation material can be solidified by mixing the calcium silicate insulation material at a weight ratio of 50% or more.
That is, in the above-mentioned volume reduction processing apparatus, if the rock wool insulation material and the calcium silicate insulation material are sequentially introduced into the hopper 1 at a predetermined ratio, the above-mentioned The two types of materials are uniformly mixed and supplied to the volume reducing machine 8.
