この発明は、軽くて粉末化しにくに粒状体、例
えばモミガラ等を粉末化する方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for pulverizing granular materials that are light and difficult to pulverize, such as rice hulls.
粉末化においては、実施例のごとく被粉末化物
を、ベルトグラインダー糖の研削面５ａ，５a′に
開放状態で圧接して研削し、粉末化することが、
作業性の点で好ましい。しかし、軽く、かつ粒状
のものは、開放状態では飛散し、それ自身のみで
直接に研削面に圧接することは不可能に近い。こ
のため、軽い粒状体は、従来では第５図に示す石
臼方式によつて粉状化が行われている。この方式
は、同図に示すように、皿状の研削盤１０，１１
を重ね合わせ、下側研削盤１１を回転させた状態
で、その中に、被研削物（粒状体ａ）を投入して
保持しながら、両研削盤１０，１１の周縁対向部
でもつて粒状物ａを研削して粉末化する。
In powdering, as in the example, the material to be powdered is pressed against the grinding surfaces 5a, 5a' of the belt grinder sugar in an open state, and ground and powdered.
Preferable in terms of workability. However, light and granular materials scatter in an open state, and it is almost impossible to directly press them against the grinding surface by themselves. For this reason, light granules have conventionally been pulverized by the stone mill method shown in FIG. As shown in the figure, this method uses dish-shaped grinding machines 10 and 11.
With the lower grinding machine 11 rotating, the object to be ground (granular material a) is put into it and held, and the granular material is removed from the periphery of both grinding machines 10 and 11 at opposing peripheral parts. Grind and powder a.
しかしながら、この方式は、両研削盤１０，１
１の研削面間隙ｔを狭くすると、粉末化度合は増
すが、その間隙ｔへの粒状体ａの喰い込みが悪く
なるとともに、微粉末化には１つの粒状体の研削
時間が長くなり、作業性が低下するとともに、摩
擦熱による製品の変質の問題が出る。このため、
従来では、200メツシユ以上の粉末化は困難であ
つた。一方、間隙ｔを広げると、喰い込み度合は
向上するが、粉末化度合は低下する。すなわち、
製品が粗くなる。 However, in this method, both grinders 10, 1
If the gap t between the grinding surfaces of No. 1 is narrowed, the degree of pulverization will increase, but the granules a will not be able to penetrate into the gap t, and the grinding time for each granule will be longer for pulverization. In addition to this, there is a problem of deterioration of the product due to frictional heat. For this reason,
Conventionally, it was difficult to powder more than 200 meshes. On the other hand, when the gap t is widened, the degree of biting improves, but the degree of powdering decreases. That is,
The product becomes rough.
この発明は、以上の点に留意し、軽くて粉末化
しにくい粒状体でも、円滑に粉末化でき、かつ、
微粉末化を容易にし得るようにすることを目的と
する。 With the above points in mind, the present invention enables even light and difficult-to-pulverize granular materials to be smoothly powdered, and
The purpose is to facilitate pulverization.
上記目的を達成するため、この発明にあつて
は、筒内に、被粉末化粒状体を圧縮充填し、その
圧縮状態の粉状体を、前記筒に対し、相対的に移
動する研削面に圧接し、研削して粉末とするよう
にしたのである。
In order to achieve the above object, the present invention compresses and fills a cylinder with granular material to be powdered, and transfers the compressed powder onto a grinding surface that moves relative to the cylinder. They were pressed together and ground into powder.
上記圧縮状態は、冷凍されたものとすることが
できる。 The compressed state may be frozen.
このように構成される粒状体の粉末化方法にあ
つては、被粉末化粒状体の研削面への圧接状態
は、その周囲が筒によつて保持（固定）されてい
るため、開放状態でも、圧接面の周囲粒状体が飛
び散ることなく、確実に研削されて粉末化する。
In the method of pulverizing granules configured in this way, the granules to be pulverized can be pressed against the grinding surface even in an open state because the periphery of the granules is held (fixed) by the cylinder. , the granules surrounding the pressure contact surface are reliably ground and powdered without scattering.
なお、圧縮状態が冷凍化されておれば、その冷
凍化によつて粒状体が硬くなるとともに、粒状体
相互間の結合も強くなつて大きな塊りとなるた
め、研削作用がより円滑となる。 Note that if the compressed state is frozen, the granules become hard due to the freezing, and the bonds between the granules become stronger, forming a large lump, so that the grinding action becomes smoother.
〔実施例 １〕
まず、第１図に示すように、氷の筒１（例え

２の冷水とともに充填圧縮し、これを冷凍する。
この冷凍により、冷水は氷３となり、氷の中に粒
状体２が圧縮状態で混在して氷柱４となる。[Example 1] First, as shown in Fig. 1, an ice tube 1 (for example, outer diameter 100 mmφ, inner diameter 80 mmφ, height 200 mm) is made, and the granular material 2 to be powdered, such as rice hulls, is placed in it. It is filled and compressed with cold water and then frozen.
By this freezing, the cold water turns into ice 3, and the granules 2 are mixed in the ice in a compressed state to form icicles 4.
この氷柱４を、第２図に示すように、ベルトグ

度の揃つた微粉末ｂとなる。 As shown in FIG. 2, when this icicle 4 is pressed against the grinding surface 5a of the belt grinder 5, the icicle 4
The pressure contact part is ground by the running grinding surface 5a, and the ground ice powder and powdery granules (fine powder b) are scattered into the cover 6, and are eventually collected in a container 7 as a colloid. Ru. this,
If the water is removed and the powder is dried, the entire amount of the ground material becomes a fine powder b with uniform fineness without sieving.

とするとよい。[Example 2] In this example, an iron cylinder 1' is used as the cylinder 1. First, as shown in Fig. 3, a pressure rod is placed inside the iron cylinder 1' (50φ x 49φ x 100). The granular material 2 to be powdered is sufficiently filled in a compressed state through the tube 9 . Next, as shown in FIG.
It is pressed against the grinding surface 5'a of a grinder 5' made of a whetstone, and ground in the same manner as described above, and the ground fine powder b is collected into the container 7. This fine powder b
is passed through a magnetic separator to remove iron. in this case,
It is preferable that the cylinder 1' be brought into pressure contact with the grinding surface 5' by means other than the pressure rod 9, and that the granular material 2 be kept in a frozen state.
粒状体２の種類によつては、筒１，１′にプラ
スチツク、竹等を採用できる。両者（粒状体２と
