It's not easy. For this reason, it is necessary to check the quality and performance of the received aggregate, which increases the labor and cost on the receiving side. Furthermore, since most of the receiving side (users) currently exist within a radius of about 50m from the quarry or crushed stone factory, and the supply range is limited, the receiving side is compatible with a wide variety of uses. When trying to obtain the material, there was a problem that the logistics became difficult.

  By the way, in Patent Literature 1 and Patent Literature 2, even when the nature and state of the earth and sand as raw materials are various, the quality of the earth and sand product is improved without causing an increase in industrial waste. In order to promote reuse, before using the self-propelled soil conditioner to perform multiple production processes, including a receiving process with a sediment hopper, a mixing process with a mixing device, and a discharging process with a discharge conveyor, An earth and sand product production system has been proposed in which at least one of pre-classification, crushing, crushing, and additive addition is performed by a stationary conveyor, a sieving device, a crushing device, and a magnetic separator.

  These systems described in Patent Documents 1 and 2 are limited to the production of products using earth and sand as a raw material, and there are few types of products, and a relatively small scale that combines a self-propelled soil improvement machine and stationary equipment. System.

  Further, Patent Document 3 discloses a coal-fired thermal power plant that accepts coal ash generated at a coal-fired thermal power plant and provides a combined system for coal ash treatment and distribution efficiency that can be delivered for various uses. A facility for receiving coal ash generated at the power plant, a plurality of storage facilities, a classifier for classifying coal ash, a mixer for mixing coal ash with each other or coal ash and other raw materials, and coal for a plurality of uses Coal ash treatment / distribution combined systems equipped with shipping equipment for shipping ash or a mixture of coal ash and other raw materials have been proposed.

  The system disclosed in Patent Document 3 is also limited to coal ash for effectively using coal ash as waste, and has fewer types of products than aggregates. In addition, since coal ash is a soft granular material unlike hard granular materials such as crushed stone and aggregate, the handling method and equipment are also different. Therefore, it is difficult to apply the invention described in Patent Document 3 to the production and shipment of aggregates.

  Next, an operation example of the business establishment 10 having the above configuration will be described in detail for each type of aggregate received.

  First, the case where limestone coarse aggregate is received will be described with reference to FIG.

  The coarse limestone aggregate transported from the quarry or crushed stone factory 2 is received by the receiving facility 12 and temporarily stored in the first storage 14 for the coarse limestone aggregate. If the materials received from a plurality of different quarries or quarries 2 are of substantially the same quality, they may be stored together, but if they are of a slightly different quality, they are preferably stored separately. Of the limestone coarse aggregate stored in the first storage place 14, the test / analysis facility 34 was tested, and it was confirmed that it could be used as it is as a coarse aggregate for concrete. The test result table is attached via 43 and shipped from the shipping facility 36 by land transportation or sea transportation.

  Of the limestone coarse aggregate stored in the first storage place 14, the test / analysis equipment 34 was used for testing, and the pulverized aggregate that was not confirmed to be usable as a coarse aggregate for concrete as it was, Those that have not been subjected to the confirmation test because they are included in a large amount are supplied to the first classifier 22 and classified using 5 mm and 20 mm as classification points.

  Aggregates classified by the first classifier 22 and having a particle size of 20 mm or more are pulverized by the pulverizer 20 until the particle size becomes less than 20 mm. On the other hand, aggregates having a particle size of 5 mm or more and less than 20 mm are washed with a washing machine 32, checked for quality with a test / analysis facility 34, and then passed through a storage tank 43 as a coarse aggregate for concrete. And shipped from the shipping facility 36 by land transportation or sea transportation.

  Aggregates classified by the first classifier 22 and having a particle size of less than 5 mm are supplied to the second classifier 23 and classified using 0.15 mm as a classification point. Then, the aggregate having a particle size of 0.15 mm or more and less than 5 mm is shipped in the same manner as the coarse aggregate through the storage tank 41 as a fine aggregate for concrete after confirming the quality and the like by the test / analysis facility 34. Ship from the facility 36. On the other hand, after confirming the quality and the like in the test / analysis facility 34, the tankal having a particle size of less than 0.15 mm is transferred from the shipping facility 36 by land transportation via the storage tank 42 as various fillers and powders for concrete admixture. Ship.

  As described above, according to this business site 10, the limestone coarse aggregate received from a plurality of different quarries or quarry factories 2 under the unified management at one business establishment is accepted. From the aggregate, it is possible to manufacture and ship tankar, fine aggregate for concrete, and coarse aggregate for concrete. At this time, the aggregate to be shipped can be adapted to the standard of concrete aggregate specified in JIS.

  Next, the case of receiving natural coarse aggregate will be described with reference to FIG. In addition, natural coarse aggregate here means natural coarse aggregates other than limestone coarse aggregate, such as granite coarse aggregate and andesite coarse aggregate.

  In parallel with the limestone aggregate, natural coarse aggregate landed from the quarry or crushed stone factory 2 is received by the receiving facility 12 and temporarily stored in the first storage place 14. The processing in the case of accepting substantially simultaneously from a plurality of different quarries or quarries 2 is the same as the case of the limestone coarse aggregate. After that, among the natural coarse aggregates stored in the first storage place 14, those that have been tested by the test / analysis facility 34 and confirmed to be usable as natural coarse aggregates for concrete are stored. The test result table is attached via the tanks 44 and 46 and shipped from the shipping facility 36 by land transportation.

  Of the natural coarse aggregates stored in the first storage place 14, those tested by the test / analysis facility 34 and not confirmed to be usable as natural coarse aggregates for concrete are used as the first. Supplied to the classifier 22 and classified using 5 mm and 20 mm as classification points.

  Aggregates classified by the first classifier 22 and having a particle size of 20 mm or more are pulverized by the pulverizer 20 until the particle size becomes less than 20 mm. On the other hand, aggregates having a particle size of 5 mm or more and less than 20 mm are washed with a washing machine 32, and then the quality and the like are confirmed with a test / analysis facility 34. Is shipped from the shipping facility 36 by land transportation.

  Further, the aggregate classified by the first classifier 22 and having a particle size of less than 5 mm is supplied to the second classifier 23 and classified using 0.15 mm as a classification point. Aggregates with a particle size of 0.15 mm or more and less than 5 mm are checked for quality by the test / analysis facility 34, and are sent by land transport with a test result table as a natural fine aggregate for concrete via the storage tank 44. Ship from the shipping facility 36. On the other hand, the crushed stone powder having a particle size of less than 0.15 mm is shipped from the shipping facility 36 by land transportation via the storage tank 45 as a ground improvement powder after confirming the quality and the like by the test / analysis facility 34.

  As described above, according to this business establishment 10, the natural coarse aggregate received from each of a plurality of different quarries or quarries 2 under the unified management at one establishment is accepted. Crushed stone powder, fine aggregate, and coarse aggregate can be manufactured and shipped from the aggregate, and aggregate that conforms to the standards for concrete aggregate specified in JIS can also be shipped.

  Next, a case where two kinds of natural aggregates are received and quality is adjusted and shipped will be described with reference to FIG. In addition, the natural aggregate here is a general natural aggregate which is not specified.

  Two kinds of natural aggregates (coarse and fine) that are transported from different quarries or crushed stone plants 2 that do not meet JIS standards are received by the receiving facility 12 and temporarily stored in the first storage 14. The quality and performance of the accepted aggregate will be confirmed.

  Next, both aggregates are classified by the first classifier 22. The aggregate having a particle size of 5 mm or more classified by the first classifier 22 is pulverized by the pulverizer 20 until the particle size becomes less than 5 mm. On the other hand, an aggregate having a particle size of 0.15 mm or more and less than 5 mm is supplied to the weighing machine 24 as a fine aggregate material.

  Aggregates crushed by the pulverizer 20 are supplied to the second classifier 23 and classified. Regarding the crushed stone powder having a particle size of less than 0.15 mm, the quality of the crushed stone is confirmed by the test / analysis facility 34, and then stored. The test result table is attached as a powder for concrete admixture through the tank 47 and shipped from the shipping facility 36 by land transportation. On the other hand, aggregates of 0.15 mm or more and less than 5 mm classified by the second classifier 23 are stored in the second storage 26 as aggregates for adjusting quality, performance, particle size, etc. for each particle size range. A classification point in the second classifier 23 is appropriately provided between a particle size range of 0.15 mm or more and less than 5 mm.

  Next, in the weighing machine 24, the aggregate from the first classifier 22 and the aggregate for adjusting the particle size from the second storage place 26 are weighed and then mixed by the mixer 28. As the aggregate for adjusting the particle size, those classified and stored as described above may be used. If the quality and the like are the same, those already stored may be used. For example, when the particle size distribution of the aggregate from the first classifier 22 is unsuitable as the natural fine aggregate for concrete, the aggregate for adjustment from the second storage place 26 is used for the insufficient particle size range. The particle size is adjusted by adding and mixing to obtain a particle size distribution that conforms to the specifications of natural fine aggregate for concrete. Further, when the aggregate from the first classifier 22 includes a component that easily causes an alkali aggregate reaction, a slag fine aggregate or the like that prevents the alkali aggregate reaction from the second storage place 26 is added to the weighing machine 24, the mixer. 28 to mix and adjust the ingredients.

  The aggregate mixed by the mixer 28 is washed by the washing machine 32, and then the quality and the like are confirmed by the test / analysis facility 34, and a test result table is attached as a natural fine aggregate for concrete through the storage tank 48. Then, it is shipped from the shipping facility 36 by land transportation.

  As described above, according to this business establishment 10, under the unified management at one business establishment, the aggregate having the desired quality is obtained by mixing two kinds of natural aggregates that are not accepted. Can be obtained, and it can be made to conform to the standards for aggregates for concrete defined in JIS.

  Next, the case where the three kinds of heavy fine aggregates are received and the performance and the like are adjusted and then shipped as heavy aggregates for ship balancers will be described with reference to FIG. Examples of the raw material for the heavy fine aggregate include scrap iron, mill scale, and iron sulfate.

  Three kinds of heavy fine aggregates transported by heavy aggregate producer 3 are received by the receiving facility 12 and stored in the first storage place 14.

  Of the heavy fine aggregates stored in the first storage place 14, the test / analysis facility 34 performs tests, and some of the iron aggregates and the like that can be used as heavy aggregates for ship balancers are stored in the storage tank 50A. The test result table is attached to the product and shipped from the shipping facility 36 by land or sea.

  Among the heavy fine aggregates stored in the first storage place 14, a test / analysis facility 34 performs a test. For example, because the shape and particle size are not suitable, those that cannot be used as heavy aggregates for ship balancers as they are, Use a mixture of different shapes and sizes. Each of these is supplied to the weighing machine 24 and weighed and then mixed by the mixer 28 to adjust the shape and particle size, obtain a homogeneous heavy fine aggregate, and supply it to the test / analysis facility 34. As a balancer weight aggregate, the test result table is attached via the storage tank 50B, and the product is shipped from the shipping facility 36 by land transportation or sea transportation. For example, since the shape of a mill scale is flat, it is used by mixing with granular scrap iron.

  As described above, according to this business site 10, under the centralized management at one business site, from the three types of heavy aggregates that have been accepted, heavy bones for ship balancers with a good balance of shape and particle size. Since the material can also be obtained, the quality of heavy aggregate for ship balancers can be stabilized and the distribution efficiency can be improved.
