When the molten slag from the blast furnace is tapped &amp; subjected to a process of rapid cooling by jets of pressurized water, it forms granules, which is called granulated slag. The slag hardens when it reacts with water, getting a hydraulic property that provides increased strength over a period of time.<\/p>\n<p>GGBS, when used along with OPC (Ordinary Portland Cement) in concrete or mortar mix, imparts unique properties to obtain very strong and durable mix.<\/p>\n<p>GGBS is widely used by the ready-mix concrete plants, apart from major construction projects in India. It is known to almost double the lifespan of structures.<\/p>\n<p>GoodRich offers vertical roller mills from China for making GGBS. Vertical roller mill is a type of grinder used to grind the materials into extremely fine powder. It is an energy-efficient alternative for ball mill.<\/p>\n<p>Vertical roller mills have been developed in China with German &amp; Japanese technologies. They can be used for grinding of clinker, cement &amp; slag. The available capacities are from 500 tons to 3,000 tons per day. A vertical roller mill combines intermediate crushing, grinding, drying, separating &amp; conveying processes. While grinding the slag, the fineness will be as per Blaine<u>&gt;<\/u>4,200 cm<sup>2<\/sup>\/gram. The initial moisture of 15% in the slag will be reduced to 0.5% in the process.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-299 aligncenter\" src=\"https:\/\/goodrichmagma.com\/\/wp-content\/uploads\/2017\/08\/verticalgrindingmillforslag.jpg\" alt=\"\" width=\"604\" height=\"376\" srcset=\"https:\/\/goodrichmagma.com\/wp-content\/uploads\/2017\/08\/verticalgrindingmillforslag.jpg 604w, https:\/\/goodrichmagma.com\/wp-content\/uploads\/2017\/08\/verticalgrindingmillforslag-420x261.jpg 420w\" sizes=\"auto, (max-width: 604px) 100vw, 604px\" \/><\/p>\n<p><strong>Advantages of vertical roller mill \u2013<\/strong><strong>\u00a0<\/strong><\/p>\n<ul>\n<li>20-50% less energy needed than ball mill systems<\/li>\n<li>Can be used for Portland cement, slag and blended cements<\/li>\n<li>High productivity with stable &amp; reliable operation<\/li>\n<li>Design optimized for maintenance<\/li>\n<li>Effective drying when grinding blast furnace slag or blended cements with wet components<\/li>\n<li>Consistent cement quality with easy-to-adjust quality parameters<\/li>\n<li>Good particle size distribution; modification of PSD (particle size distribution) curve possible<\/li>\n<li>High fineness<\/li>\n<li>Small variation in the quality<\/li>\n<li>Long lifetime<\/li>\n<li>Simple, compact layout<\/li>\n<li>Proven technology<\/li>\n<\/ul>\n<p><a href=\"https:\/\/goodrichmagma.com\/index.php\/technologies-equipments-from-china-2\/\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-1040 alignright\" src=\"https:\/\/goodrichmagma.com\/wp-content\/uploads\/2017\/11\/back-button.jpg\" alt=\"\" width=\"90\" height=\"45\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>GGBS is granulated blast furnace slag, ground to very high fineness.
