In this study, grinding tests were carried out on limestone to clarify the comminution mechanism in the KD-3.\nA particular attention was paid to important factors such as size of the grinding media\n(steel balls of ¢ 10 mm, ¢ 13 mm, ¢ 16 mm, ¢ 20 mm), the speed of the stirring screw [from\n1.08s-1 (65rpm) to 1.58s-1 (95rpm)] and the role of nets in the classifying column. The study has revealed an optimum efficiency for steel balls of ¢ 20 mm size and stirring screw rotating at 1.58s-1 (95 rpm). Besides, the maximum particle diameters of products were indicated by the corrected curve which is estimated by the assumption of Stoke's law. The relationship between maximum and 50% particle diameters was proportionally and by using the columns provided with nets, the overflow products were classified by high classifying efficiency.","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本素材物性学会"}]},"item_10001_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN10140273","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09199853","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"柴山, 敦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"新田, 幸人"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"森, 祐行"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ほか"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SHIBAYAMA, Atsushi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NITTA, Sachihito","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MORI, Sukeyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-16"}],"displaytype":"detail","filename":"sozai13a6.pdf","filesize":[{"value":"995.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"sozai13a6.pdf","url":"https://air.repo.nii.ac.jp/record/1298/files/sozai13a6.pdf"},"version_id":"3c257661-c400-4a48-a200-2e6eff5f2117"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Tower Mill","subitem_subject_scheme":"Other"},{"subitem_subject":"Comminution Mechanism","subitem_subject_scheme":"Other"},{"subitem_subject":"Grinding Media Size","subitem_subject_scheme":"Other"},{"subitem_subject":"Stirring Screw Speed","subitem_subject_scheme":"Other"},{"subitem_subject":"Classifying Efficiency","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"乾式タワーミル粉砕機の開発と粉砕特性に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"乾式タワーミル粉砕機の開発と粉砕特性に関する研究"}]},"item_type_id":"10001","owner":"3","path":["690"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-10-23"},"publish_date":"2008-10-23","publish_status":"0","recid":"1298","relation_version_is_last":true,"title":["乾式タワーミル粉砕機の開発と粉砕特性に関する研究"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-25T11:55:02.881680+00:00"}
