In either or both steps of stirring / mixing and pulverization, polyalkylene glycol having a saturated alkylene oxide chain with a low carbon number is sprayed into the powder / granular material to obtain a dust-free property. It is a method of obtaining powder / granular material. Here, the low carbon number specifically means that the carbon number is about 2 to 5. Further, as the polyalkylene glycol, a low viscosity liquid having a molecular weight of 1,000 or less is used. Such a polyalkylene glycol has an appropriate viscosity and is easy to scatter and float.
It has the property of easily trapping particles of m or less, and even if a relatively large amount, for example, about 2% by weight of the weight of the powder / powder, is added, it will be hydration·
It does not inhibit the curing reaction and has almost no toxicity to the living body.

る。The spraying method may be carried out by using a known sprayer capable of spraying the polyalkylene glycol so as to form a mist having a particle size of the order of μm. And, as a specific operation for spraying,
When each operation is performed in the stirring / mixing device or the crushing device, polyalkylene glycol is sprayed from each of the above devices into the spraying device. Then, by such an operation, the mist-like polyalkylene glycol floats in the device, and the fine particles scattered in the device are contacted and captured, and fall into the powder / granular material as it is. Then, fine particles of the powder, which cause dust generation when finally commercialized, are captured by polyalkylene glycol and adhered to other particles, or the fine particles are bonded to each other to form relatively large particles. The resulting product will be dust free.

粒子を確実に捕捉して発塵は抑さえられるものの、粉末
材料が急激な凝集を起こしてしまい、凝集塊のない均一
な粉末製品が得られなくなるからである。The reason why the polyalkylene glycol is sprayed is that the fine particles are surely captured and dust is suppressed by simply dropping the polyalkylene glycol, but the powder material abruptly agglomerates. This is because a uniform powder product without agglomerates cannot be obtained.

・粉粒体材料が得られる。The method of manufacturing the powder / granular material according to claim 3 of the present invention is different from the method of manufacturing according to claim 1, in place of spraying polyalkylene glycol. The point is to add a woven fabric or other fibrous material impregnated with polyalkylene glycol into a mixing device or a crushing device. Here, the amount of polyalkylene glycol impregnated into a fibrous material such as a woven fabric is about 3% or less of the weight of the powder or granular material to be treated.
After the stirring, mixing, and crushing operations are completed, the fibrous material such as woven fabric impregnated with polyalkylene glycol is removed from each device, and finally a uniform mixed powder without agglomerates is produced. As a result, a powder / granular material as a product is obtained.

Woven cloth or other fibrous material was used as a means for imparting to the granular material because the fibrous material has a large surface area for the bulk because of the large number of fine gaps between the fibers, and therefore the polyalkylene glycol This is because the fine particles in the powder / powder are trapped in the gaps when the powder is impregnated and is stirred / mixed with the dust-generating powder. That is, since the polyalkylene glycol adheres to the captured dust-generating fine particle powder, even if the fine particle powder once captured falls off from the interstices between the fibers of the fibrous material, when it is used as a product. It does not scatter or float.

あればいずれでも適用可能である。According to the method for producing a powder / powder-granular material according to claim 1, a poly-carbon compound having a saturated alkylene oxide chain having a low carbon number is provided in either one or both of stirring / mixing and pulverization. Since the alkylene glycol is sprayed into the powder / granular material, it is possible to capture and settle fine particles scattered / floating with extremely high efficiency and prevent the formation of aggregates. According to the method for producing a powder / granular material according to claim 3, a woven cloth or a fibrous material having a large number of fine gaps between fibers and thus having a large surface area against the bulk is impregnated with polyalkylene glycol, Since the particles are agitated, mixed and / or pulverized with the dust generating powder, the fine particles in the powder to be treated are captured in the gaps between the fibers of the fibrous material. Further, even if the captured fine particles fall off from the fibrous material, since the polyalkylene glycol is attached to the fine particles, the polyalkylene glycol does not scatter or float, and thus finally does not have agglomerates and is uniform. A mixed powder is obtained. Further, since the powder / powder-granular material according to claim 2 is obtained by the method according to claim 1 and the cement material according to claim 4 is obtained by the method according to claim 3, both are not provided. It becomes dusty.

In the pulverizing step by the pulverizer, triethylene glycol, polyethylene glycol having a molecular weight (Mw) of about 300, and polyethylene glycol having a molecular weight (Mw) of about 600 are prepared by a commercially available atomizer to obtain particles having a particle size of μm order. Thus, it was atomized into the pulverizer. Here, the amount of each glycol sprayed is 0.1, 0.5, or 0.5 with respect to the weight of the cement to be treated.
It was set to 1.0, 2.0 and 3.0% by weight. After the crushing process, 1 kg of cement was packed in a bag and dropped on a concrete floor from a height of 1 m per bag, and the amount of dust generated at impact (count per mi

A woven cloth having a width of 20 cm and a thickness of 0.01 cm was impregnated, and the woven cloth was placed in a mixer and mixed. Furthermore, a drop impact test was conducted in the same manner as in Example 1, and the results are shown in FIG. From the results shown in FIG. 1 and FIG. 2, the cement obtained by the method of the present invention produces a smaller amount of dust than the conventional cement (without addition of polyalkylene glycol), and therefore its dust-free property is confirmed.

Furthermore, there is no adverse effect on the hardening reaction of cement,
No hindrance to the work process was observed.

するものとなる。As described above, the method for producing a powder / powder material according to claim 1 of the present invention has a low carbon number in one or both of stirring / mixing and pulverization steps. By spraying polyalkylene glycol with saturated alkylene oxide chains into powder / granular material, it captures and sediments fine particles that are scattered / floating with extremely high efficiency and prevents the formation of aggregates. That's the way. Therefore, the powder / powder-granular material according to claim 2 obtained by this method does not generate dust at the time of opening, for example, even if it is impacted by dropping, vibrating, stirring, etc. in a packed state. The working environment for handling this can be significantly improved and improved. The method for producing a powder or granular material according to claim 3, wherein a woven cloth or a fibrous material having a large number of fine gaps between the fibers and having a large surface area with respect to the bulk is impregnated with polyalkylene glycol to generate dust. It is a method of stirring / mixing and / or crushing with a powdery powder,
The fine particles in the powder to be treated can be trapped in the spaces between the fibers of the fibrous material, and even if the trapped fine particles fall off from the fibrous material, the fine particles still have polyalkylene. Since glycol is attached, it is possible to prevent the glycol from scattering and floating, and thus it is possible to finally obtain a uniform mixed powder without agglomerates. And
The powder / powder-granular material according to claim 4 obtained by this method exhibits the same effect as that of the above-mentioned claim 2.
