しかった。2. Description of the Related Art Conventionally, in Japan, sand collected from rivers has been used as a raw material for aggregate for concrete. However, as a result of continuous collection of sand for many years, river sand resources are being depleted. In recent years, mountain sand and sea sand have been increasingly used in place of river sand. Especially in the Kanto region, mountain sand is often used as a substitute for river sand, but mountain sand contains a lot of soft stones such as clayey chunks and earth mass, and these soft stones are contained in sand. As a result, the properties of specific gravity and water absorption deteriorate, and there is a problem that it is difficult to use as an aggregate for concrete. Therefore, conventionally, crushing of soft stones contained in sand is often performed using a rod mill or a ball mill, but the crushing process using these devices involves loading raw material sand such as rods and balls. Since it is a complete batch process in which the material is filled into a cylinder together with the material (crushing medium) and rotated for a long time and then taken out, the raw material is easily over-crushed or under-crushed,
It was difficult to efficiently pulverize only soft stone to obtain good quality aggregate.

た。In view of such circumstances, the applicant of the present application has previously disclosed in Japanese Patent No. 2863158 the outer peripheral surface of a hollow rotating body provided with a required number of loading materials (crushing media) in communication with the interior. A fine pulverizer provided with a plurality of openings serving both as an inlet and an outlet for a pulverized material has been proposed. According to the fine pulverizer according to the present applicant's creation, the pulverization efficiency is higher than that of a conventional rod mill or ball mill, and it is excellent in that overpulverization does not easily occur. Since the time is easily shortened, insufficient pulverization may occur, and this point has not been sufficiently satisfactory.

From the viewpoint of the problem. Therefore, a method of obtaining recycled aggregate by crushing waste concrete generated by demolition of buildings and the like is being developed, but mortar adheres to the surface of the recycled aggregate obtained by crushing concrete waste. As a result, there is a problem that the water absorption is high and it is difficult to use it as a concrete aggregate.

ができる。The pulverizing process using the fine pulverizer according to the present invention described above may be performed by a dry process using no water or a wet process using water. However, in the case of performing a dry treatment without using water, it is preferable to attach a vibrator for vibrating the hollow rotary body in order to quickly discharge the pulverized components to the outside of the hollow rotary body. This prevents over-pulverization due to the components already crushed to the desired particle size remaining inside the hollow rotary body for a long time. As another means for preventing over-crushing, air is introduced from the supply port (7) into the container (5), and a suction device is connected to the discharge port (5) or the discharge port (15) via a duct. Accordingly, a configuration in which the pulverized components are forcibly discharged from the container (5) or the container (15) by an air stream can be preferably adopted. According to this configuration, it is possible to prevent excessive pulverization due to the component already pulverized to the desired particle diameter being introduced again into the hollow rotary body and pulverized again.

しかった。2. Description of the Related Art Conventionally, in Japan, sand collected from rivers has been used as a raw material for aggregate for concrete. However, as a result of continuous collection of sand for many years, river sand resources are being depleted. In recent years, mountain sand and sea sand have been increasingly used in place of river sand. Especially in the Kanto region, mountain sand is often used as a substitute for river sand, but mountain sand contains a lot of soft stones such as clayey chunks and earth mass, and these soft stones are contained in sand. As a result, the properties of specific gravity and water absorption deteriorate, and there is a problem that it is difficult to use as an aggregate for concrete. Therefore, conventionally, crushing of soft stones contained in sand is often performed using a rod mill or a ball mill, but the crushing process using these devices involves loading raw material sand such as rods and balls. Since it is a complete batch process in which the material is filled into a cylinder together with the material (crushing medium) and rotated for a long time and then taken out, the raw material is easily over-crushed or under-crushed,
It was difficult to efficiently pulverize only soft stone to obtain good quality aggregate.

た。In view of such circumstances, the applicant of the present application has previously disclosed in Japanese Patent No. 2863158 the outer peripheral surface of a hollow rotating body provided with a required number of loading materials (crushing media) in communication with the interior. A fine pulverizer provided with a plurality of openings serving both as an inlet and an outlet for a pulverized material has been proposed. According to the fine pulverizer according to the present applicant's creation, the pulverization efficiency is higher than that of a conventional rod mill or ball mill, and it is excellent in that overpulverization does not easily occur. Since the time is easily shortened, insufficient pulverization may occur, and this point has not been sufficiently satisfactory.

From the viewpoint of the problem. Therefore, a method of obtaining recycled aggregate by crushing waste concrete generated by demolition of buildings and the like is being developed, but mortar adheres to the surface of the recycled aggregate obtained by crushing concrete waste. As a result, there is a problem that the water absorption is high and it is difficult to use it as a concrete aggregate.

Since the pulverizing process can be performed by the two hollow rotating bodies, the pulverizing processing capability is high, and the installation area can be smaller than when two fine pulverizers are separately installed. Also,
For example, when a hard soft stone and a soft soft stone are contained in the object to be crushed, the soft soft stone can be crushed in the first hollow rotator, and the hard soft stone that cannot be crushed in the first hollow rotator can be used. Can be crushed in the second hollow rotator, so that a high-quality aggregate can be efficiently obtained in a short time.

ができる。The pulverizing process using the fine pulverizer according to the present invention described above may be performed by a dry process using no water or a wet process using water. However, in the case of performing a dry treatment without using water, it is preferable to attach a vibrator for vibrating the hollow rotary body in order to quickly discharge the pulverized components to the outside of the hollow rotary body. This prevents over-pulverization due to the components already crushed to the desired particle size remaining inside the hollow rotary body for a long time. As another means for preventing over-crushing, air is introduced from the supply port (7) into the container (5), and a suction device is connected to the discharge port (5) or the discharge port (15) via a duct. Accordingly, a configuration in which the pulverized components are forcibly discharged from the container (5) or the container (15) by an air stream can be preferably adopted. According to this configuration, it is possible to prevent excessive pulverization due to the component already pulverized to the desired particle diameter being introduced again into the hollow rotary body and pulverized again.
