FIG. 2 is a flow chart according to the method of sand preparation for waste stone of the present invention. As shown in FIGS. 1 to 2, the sand making facility 10 for waste stone of the present embodiment is a facility for making sand 4 from the waste stone 1, and is comprised of an incineration unit 20 and a crushing unit 30. It is
造砂設備 1 0で処理可能な廃石材 1としては、 切りかすや古墓、 古くなつたコン クリート、 砂利等、 種々の石材を使用することができる。 また、 石材は、 花崗岩や 大理石、 砂岩など、 種々の素材のものを使用できる。  Sand processing equipment 10 As various types of waste stone 1 that can be treated, it is possible to use various stone materials such as cuttings, old tombs, old concrete, gravel and so on. Stones can be made of various materials such as granite, marble and sandstone.
まず、 焼却装置 2 0を説明する。  First, the incinerator 20 will be described.
図 3は焼却装置 2 0の概略斜視図である。 同図に示すように、 焼却装置 2 0は、 廃石材 1を焼却する装置であり、 容器 2 1、 蓋 2 2およびバーナー 2 3から構成さ れたものである。  FIG. 3 is a schematic perspective view of the incinerator 20. As shown in the figure, the incinerator 20 is a device for incinerating the waste stone 1 and is composed of a container 21, a lid 22 and a burner 23.
容器 2 1は、 上部が開口した槽であり、 内部に廃石材 1を収容するための収容部 を備えており、 内壁には耐火レンガが敷設されている。  The container 21 is a tank whose upper portion is open, and is provided with an accommodating portion for accommodating the waste stone 1 inside, and a firebrick is laid on the inner wall.
この容器 2 1の上部開口には、 開閉自在に蓋 2 2が取り付けられている。 蓋 2 2 を開けることにより、 容器 2 1の内部に廃石材 1を収容したり、 焼却後の脆弱石材 2を取り出すことができる。 蓋 2 2を閉めることにより、 容器 2 1の内部をパーナ —2 3による熱により高温に保って焼却することができる。 前記容器 2 1の内部には、 バーナー 2 3が配設されている。 このバーナー 2 3に よって、 容器 2 1の内部に収容されている廃石材 1を焼却することができる。 A lid 22 is attached to an upper opening of the container 21 so as to be openable and closable. By opening the lid 2 2, the waste stone 1 can be accommodated inside the container 2 1 or the fragile stone 2 after incineration can be taken out. By closing the lid 22, the inside of the container 21 can be kept at a high temperature by the heat of the panner 23 and incinerated. A burner 23 is disposed inside the container 21. The waste stone material 1 accommodated inside the container 21 can be incinerated by the burner 23.
この焼却装置 2 0によって廃石材 1を焼却すると、 その内部の石粒や水等が膨張 するので、 廃石材 1を脆くして脆弱石材 2にすること力できる。  When the waste stone material 1 is incinerated by the incinerator 20, the stone particles, water, etc. inside expand, so that the waste stone material 1 can be made brittle and made into fragile stone material 2.
つぎに、 破砕装置 3 0を説明する。  Next, the crushing apparatus 30 will be described.
図 4は破碎装置 3 0の正面図である。 図 5は破砕装置 3 0の側面図である。 図 4 〜図 5に示すように、 破砕装置 3 0は、 脆弱石材 2を破碎する装置であり、 投入部 3 1、 一対の一次破砕ロール 3 2 , 3 2、 一対の二次破碎ロール 3 3， 3 3および 排出部 3 4から構成されたものである。  FIG. 4 is a front view of the breakdown device 30. FIG. 5 is a side view of the crusher 30. FIG. As shown in FIGS. 4 to 5, the crushing apparatus 30 is an apparatus for breaking the fragile stone 2, and the input part 31, a pair of primary crushing rolls 32, 32, a pair of secondary crushing rolls 33 , 3 3 and the discharge unit 34.
投入部 3 1は、 例えばホッパーであり、 投入部 3 1に脆弱石材 2を投入すること ができる。  The input part 31 is, for example, a hopper, and the fragile stone 2 can be inserted into the input part 31.
投入部 3 1の下方には、 左右一対の一次破砕ロール 3 2 , 3 2が水平軸廻りに回 転自在に設けられている。 この一対の一次破碎ロール 3 2 , 3 2を回転させること により、 その間に挟まれた脆弱石材 2を破砕して、 約 1 0〜 3◦ [mm]粒径の小石 2 Bすることができる。  A pair of left and right primary crushing rolls 32 and 32 is provided below the input unit 31 so as to be rotatable about a horizontal axis. By rotating the pair of primary failure rolls 32 3, the fragile stone material 2 sandwiched between them can be broken into pebbles 2B with a particle diameter of about 10 to 3 ° [mm].
前記一次破砕ロール 3 2 , 3 2の下方には、 左右一対の二次破砕ロール 3 3， 3 3が水平軸廻りに回転自在に設けられている。 この一対の二次破砕ロール 3 3， 3 3を回転させることにより、 その間に挟まれた小石 2 Bを破碎して、 約 0 . 7〜3 . 2 [mm]粒径の砂 4にすることができる。  A pair of left and right secondary crushing rolls 33, 33 is rotatably provided around the horizontal axis below the primary crushing rolls 32, 32. By rotating this pair of secondary crushing rolls 33, 33, the pebbles 2 B sandwiched between them are broken into sand 4 having a particle diameter of about 0.7 to 3.2 [mm]. Can.
よって、 破砕装置 3 0によれば、 投入部 3 1から投入された脆弱石材 2を、 一対 の破砕ロール 3 2， 3 2並びに一対の二次破砕ロール 3 3， 3 3によつて破砕して 約 0. 7〜 3. 2 [mm]粒径の砂 にすることができる。  Therefore, according to the crusher 30, the fragile stone material 2 fed from the feeding section 31 is crushed by the pair of crushing rolls 32, 32 and the pair of secondary crushing rolls 33, 33. It can be sand of about 0.7 to 3.2 [mm] particle size.
砂 4は、 墓の敷砂やコンクリートの骨材等に使用することができるので、 利用価 値が高い。  Sand 4 can be used as a bed sand for tombs, aggregate for concrete, etc., so its value is high.
つぎに、 本発明の造砂方法を説明する。  Below, the sand making method of this invention is demonstrated.
図 2で示すように、 まず、 摘装置 2 0によって廃石材 1を講すると、 その内 部の石粒や水等が 3彭張するので、 廃石材 1を脆くして脆弱石材 2にすることができ る （S 1 ) 。  As shown in Fig. 2, first, if the waste stone 1 is provided by a stripping device 20, the stone particles and water etc. in the inner part will be stretched by 3 feet, so make the waste stone 1 brittle and make it a fragile stone 2 Can do it (S 1).
つぎに、 破砕装置 3 0によって、 投入部 3 1から投入された脆弱石材 2を、 一対 の破碎ロール 3 2 , 3 2並びに一対の二次破碎口一ル 3 3， 3 3によって破砕して 約 0. 7〜3. 2 [mm]粒径の砂 4にすることができる （S 3 ) 。 Next, the fragile stone material 2 introduced from the introduction part 31 by the crushing device 30 is paired. Can be crushed to a sand 4 with a particle size of about 0.7 to 3.2 [mm] (S 3) ).
前記焼却後の脆弱石材 2を破砕装置 3 0の投入部 3 1に投入して破砕する前に、 脆弱石材 2をハンマー等により叩いて割り、 小さな粗石 3にしておく （S 2 ) と、 好適である。 脆弱石材 2は、 脆くなつているのでハンマー等で、 叩くだけで、 簡単 に割れて小さな粗石 3にすることができる。  Before the fragile stone material 2 after the incineration is put into the charging unit 31 of the crushing apparatus 30 and crushed, the fragile stone material 2 is broken by a hammer or the like to divide it into small coarse stones 3 (S 2), It is suitable. The fragile stone 2 is fragile and can be easily broken into small cobbles 3 simply by tapping with a hammer or the like.
小さな粗石 3を破碎するのは、 小型の破砕装置により十分破砕処理できる。 この ため、 設備の省スペース化を図ることができるという効果を奏する。  Breaking small cobbles 3 can be sufficiently crushed by a small crusher. As a result, space saving of equipment can be achieved.
つぎに、 本実施形態の廃石材の造砂設備 1 0による作用効果を説明する。  Next, the function and effect of the sand making facility 10 of waste stone of the present embodiment will be described.
本実施形態の廃石材の造砂設備 1 0によれば、 焼却装置 2 0によって廃石材 1を 焼却して、 焼却後の廃石材 1を脆くして脆弱石材 2にすることが'できるので、 破砕 装置 3 0によって脆弱石材 2を破砕することにより、 砂 4を簡単に造ることができ る。  According to the sand making facility 10 of waste stone of this embodiment, since the waste stone 1 can be incinerated by the incinerator 20 and the waste stone 1 after burning can be made brittle and made into fragile stone 2, By crushing fragile stone 2 with crushing equipment 30, sand 4 can be easily made.
よって、 大きな廃石材であっても簡単に廃棄処理ができ、 しかも、 廃石材 1から 禾拥価値のある砂 4を簡単に造ることができるという効果を奏する。 産業上の利用可能性  Therefore, even large waste stone materials can be easily disposed of, and moreover, it is possible to easily produce sand 4 of value from waste stone materials 1. Industrial applicability
第 1発明によれば、 焼却装置によって廃石材を焼却して、 焼却後の廃石材を脆く することができるので、 破砕装置によって焼却後の廃石材を破砕することにより、 砂を簡単に造ることができる。 よって、 大きな廃石材であっても簡単に廃棄処理が でき、 しかも廃石材から利用価値のある砂を造ることができる。  According to the first aspect of the invention, since the waste stone can be incinerated by the incinerator and the waste stone after incineration can be made brittle, sand can be easily formed by crushing the waste stone after incineration by the crusher. Can. Therefore, even large waste stone materials can be easily disposed of, and it is possible to produce useful sand from waste stone materials.
第 2発明によれば、 廃石材を焼却することによって廃石材を脆くすることができ るので、 焼却後の廃石材を破砕することにより、 砂を簡単に造ることができる。 よ つて、 大きな廃石材であっても簡単に廃棄処理ができ、 しかも廃石材から利用価値 のある砂を造ることができる。  According to the second aspect of the invention, since the waste stone material can be made brittle by incinerating the waste stone material, sand can be easily produced by crushing the waste stone material after the incineration. Therefore, even large waste stone materials can be easily disposed of, and it is possible to produce useful sand from the waste stone materials.
第 3発明によれば、 焼却後の廃石材を叩いて割ることにより、 簡単に小さな粗石 にすることができる。 小さな粗石を破砕するのに、 大型の破砕装置は必要なく小型 の破砕装置により十分破碎処理できる。 このため、 設備の省スペース化を図ること ができる。  According to the third aspect of the present invention, it is possible to easily make a small crude stone by tapping and dividing the waste stone after incineration. In order to crush small cobbles, a large crusher is not necessary, and a small crusher can be sufficiently destroyed. Therefore, space saving of equipment can be achieved.
