dir=\"ltr\"><strong>Challenge:<\/strong> The original chute ledge liners were rear-bolted and needed several unique profiles per shelf. Removing them meant jackhammering the underside of the shelf, and corroded bolts often had to be cut free with hot work in a confined space. Chute wear was driving shutdowns roughly every four weeks.<\/p>\n<p dir=\"ltr\"><strong>Solution:<\/strong> We designed two standardised ledge liner components that fit every shelf radius, secured from the front with T-bolts that release with a half-turn. We also redesigned the spoon liner profile to improve ore flow onto the conveyor.<\/p>\n<p dir=\"ltr\"><strong>Result:<\/strong> Tonnes processed per shutdown rose from about 3M to 12M, and shutdowns fell from about 12 a year to 3. Jackhammering and confined-space hot work were removed from the change-out.<\/p>\n<\/div><div style=\"text-align:left;\"><style type=\"text\/css\">.fusion-button.button-1 {border-radius:0px;}<\/style><a class=\"fusion-button button-flat fusion-button-default-size button-default button-1 fusion-button-default-span fusion-button-default-type\" target=\"_blank\" rel=\"noopener noreferrer\" href=\"https:\/\/quarrymining.com.au\/forefront\/case-studies\/mhs-chute-ledge-liner-system\/\"><span class=\"fusion-button-text\">Full Case Study [PDF]<\/span><i class=\"fa-file-pdf fas button-icon-right\" aria-hidden=\"true\"><\/i><\/a><\/div><div class=\"fusion-separator fusion-full-width-sep\" style=\"align-self: center;margin-left: auto;margin-right: auto;margin-top:20px;margin-bottom:20px;width:100%;\"><div class=\"fusion-separator-border sep-single sep-solid\" style=\"border-color:#ef5927;border-top-width:1px;\"><\/div><\/div><div class=\"fusion-text fusion-text-3\"><p><a href=\"https:\/\/quarrymining.com.au\/forefront\/case-studies\/\">&lt; Back to Case Studies<\/a><\/p>\n<\/div><\/div><\/div><style type=\"text\/css\">.fusion-body .fusion-builder-column-2{width:50% !important;margin-top : 0px;margin-bottom : 20px;}.fusion-builder-column-2 > .fusion-column-wrapper {padding-top : 0px !important;padding-right : 0px !important;margin-right : 3.84%;padding-bottom : 0px !important;padding-left : 0px !important;margin-left : 3.84%;}@media only screen and (max-width:1024px) {.fusion-body .fusion-builder-column-2{width:50% !important;order : 0;}.fusion-builder-column-2 > .fusion-column-wrapper {margin-right : 3.84%;margin-left : 3.84%;}}@media only screen and (max-width:640px) {.fusion-body .fusion-builder-column-2{width:100% !important;order : 0;}.fusion-builder-column-2 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}<\/style><\/div><style type=\"text\/css\">.fusion-body .fusion-flex-container.fusion-builder-row-2{ padding-top : 0px;margin-top : 0px;padding-right : 0px;padding-bottom : 0px;margin-bottom : 0px;padding-left : 0px;}<\/style><\/div><\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":5877,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_seopress_robots_primary_cat":"none"},"categories":[18],"tags":[],"_links":{"self":[{"href":"https:\/\/quarrymining.com.au\/forefront\/wp-json\/wp\/v2\/posts\/5864"}],"collection":[{"href":"https:\/\/quarrymining.com.au\/forefront\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/quarrymining.com.au\/forefront\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/quarrymining.com.au\/forefront\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/quarrymining.com.au\/forefront\/wp-json\/wp\/v2\/comments?post=5864"}],"version-history":[{"count":13,"href":"https:\/\/quarrymining.com.au\/forefront\/wp-json\/wp\/v2\/posts\/5864\/revisions"}],"predecessor-version":[{"id":6335,"href":"https:\/\/quarrymining.com.au\/forefront\/wp-json\/wp\/v2\/posts\/5864\/revisions\/6335"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/quarrymining.com.au\/forefront\/wp-json\/wp\/v2\/media\/5877"}],"wp:attachment":[{"href":"https:\/\/quarrymining.com.au\/forefront\/wp-json\/wp\/v2\/media?parent=5864"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/quarrymining.com.au\/forefront\/wp-json\/wp\/v2\/categories?post=5864"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/quarrymining.com.au\/forefront\/wp-json\/wp\/v2\/tags?post=5864"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
