The quarry crushing plant\u00a0consisted of a jaw and cone crusher; a configuration that may not\u00a0always produce the desired particle shape.\u00a0After careful analysis of the particle shape requirements and\u00a0plant output tonnage (approx. 60 mtph) being too low for the\u00a0efficient running of a larger machine, H-E Parts recommended\u00a0the Auspactor\u2122 VS75RR vertical shaft impact crusher.<\/p>\n<p>The\u00a0Auspactor\u2122 vertical shaft impact crushers have lower operating\u00a0costs than competing machines and are renowned for improving\u00a0aggregate particle shape. Being the smallest of the Auspactor\u2122\u00a0range; the Auspactor\u2122 VS75RR suited the customer\u2019s\u00a0requirements perfectly. A VS75RR machine fitted with a variable speed drive (VSD) was\u00a0installed to single pass crush -22 +3.15mm product from the\u00a0cone crusher. The VSD allowed fine tuning of the Auspactor\u2122\u00a0rotor speed to achieve improved particle shape whilst turning\u00a0the weaker particles into sand. An immediate improvement\u00a0in aggregate shape was observed and subsequent concrete\u00a0batch testing showed a significant improvement in compressive\u00a0strength due to the improved aggregate quality, opening the\u00a0opportunity for cost savings for the customer.\u00a0Since installing the Auspactor\u2122 VS75RR the following benefits\u00a0have been achieved:<\/p>\n<ul>\n<li>Greatly improved aggregate particle shape.<\/li>\n<li>Greatly improved aggregate particle strength.<\/li>\n<li>Concrete plant cost savings were a result of the production\u00a0of superior strength aggregate material.<\/li>\n<\/ul>\n\n\t\t<style type=\"text\/css\">\n\t\t\t#gallery-1 {\n\t\t\t\tmargin: auto;\n\t\t\t}\n\t\t\t#gallery-1 .gallery-item {\n\t\t\t\tfloat: left;\n\t\t\t\tmargin-top: 10px;\n\t\t\t\ttext-align: center;\n\t\t\t\twidth: 16%;\n\t\t\t}\n\t\t\t#gallery-1 img {\n\t\t\t\tborder: 2px solid #cfcfcf;\n\t\t\t}\n\t\t\t#gallery-1 .gallery-caption {\n\t\t\t\tmargin-left: 0;\n\t\t\t}\n\t\t\t\/* see gallery_shortcode() in wp-includes\/media.php *\/\n\t\t<\/style>\n\t\t<div id='gallery-1' class='gallery galleryid-771501 gallery-columns-6 gallery-size-thumbnail'><dl class='gallery-item'>\n\t\t\t<dt class='gallery-icon landscape'>\n\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/www.h-eparts.com\/wp-content\/uploads\/2018\/12\/aggregate-after-ausp-150x150.jpg\" class=\"attachment-thumbnail size-thumbnail\" alt=\"Aggregate output after Auspactor crushing\" srcset=\"https:\/\/www.h-eparts.com\/wp-content\/uploads\/2018\/12\/aggregate-after-ausp-150x150.jpg 150w, https:\/\/www.h-eparts.com\/wp-content\/uploads\/2018\/12\/aggregate-after-ausp-300x300.jpg 300w\" sizes=\"auto, (max-width: 150px) 100vw, 150px\" \/>\n\t\t\t<\/dt><\/dl><dl class='gallery-item'>\n\t\t\t<dt class='gallery-icon landscape'>\n\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/www.h-eparts.com\/wp-content\/uploads\/2018\/12\/aggregate-before-ausp-150x150.jpg\" class=\"attachment-thumbnail size-thumbnail\" alt=\"Aggregate before Auspactor crushing\" srcset=\"https:\/\/www.h-eparts.com\/wp-content\/uploads\/2018\/12\/aggregate-before-ausp-150x150.jpg 150w, https:\/\/www.h-eparts.com\/wp-content\/uploads\/2018\/12\/aggregate-before-ausp-300x300.jpg 300w\" sizes=\"auto, (max-width: 150px) 100vw, 150px\" \/>\n\t\t\t<\/dt><\/dl>\n\t\t\t<br style='clear: both' \/>\n\t\t<\/div>\n\n","protected":false},"excerpt":{"rendered":"In a NSW aggregate quarry, the customer used a portion of\u00a0the materials produced for their concrete production business,\u00a0thus requiring precise [&hellip;]","protected":false},"featured_media":771502,"template":"","tags":[],"class_list":["post-771501","white-papers","type-white-papers","status-publish","has-post-thumbnail","hentry"],"acf":[],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.h-eparts.com\/es\/wp-json\/wp\/v2\/white-papers\/771501","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.h-eparts.com\/es\/wp-json\/wp\/v2\/white-papers"}],"about":[{"href":"https:\/\/www.h-eparts.com\/es\/wp-json\/wp\/v2\/types\/white-papers"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.h-eparts.com\/es\/wp-json\/wp\/v2\/media\/771502"}],"wp:attachment":[{"href":"https:\/\/www.h-eparts.com\/es\/wp-json\/wp\/v2\/media?parent=771501"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.h-eparts.com\/es\/wp-json\/wp\/v2\/tags?post=771501"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
