You should learn about mining inserts and various mining bits tipped with them, whether you work for crude&gas industry, mining industry, or construction. I can see why it comes cause you realize works in these industries, more knowledge of tools you obtain, less hazardous condition and risk your guys will confront. As a manufacturer with exportation of mining tips gradually taking up one fourth of our whole annual throughput, we are thrilled to write this blog sharing some fundamental stuff about carbide mining tips that we are fabricating and familiar with. It couldn\u2019t be better if it assists in knowing the categories of drilling tips made of carbide and what mining rigs they are used on.<\/p>\r\n\r\n\r\n\r\n

Simply put,\u00a0that\u2019s because\u00a0on the microscopic level\u00a0if a cracking occurs , it has to either pass through WC particles or get around them in a zigzag way. No matter which way the cracking goes, WC particles in bigger grain size cost it more fracture energy to penetrate, and meanwhile more surface area to skirt around. Consequently, the cracking propagation can be restrained. Statistic shows coarse carbide is 20% to 30% stronger than conventional carbide in toughness.<\/p>\r\n\r\n\r\n\r\n

Percussion rock mining bit<\/strong><\/h1>\r\n\r\n\r\n\r\n

Exactly as its name implies, The function of percussion rock mining bits is largely dependent on the principle of percussion mechanism. Its built-in motor generates a percussive energy periodically thrust its bore head into ground creating many crackings and within each interval, the bore head rotates at a certain degree, which results in all overburden in the area that the rock mining bit covers gets smashed into small debris. Then a compressed air or a stream of high-pressure fluid comes out from a hole in bore stem and flush away all debris to form a round hole.<\/p>\r\n\r\n\r\n\r\n

In general, percussion rock drills are utilized for two main purposes,\u00a0the first of which is to bore blast holes for filling with\u00a0explosives.\u00a0Secondly, It used for crashing some solid material for good, such as cement blocks.<\/p>\r\n\r\n\r\n\r\n

PDC mining bit(Polycrystalline diamond compact)<\/strong><\/h1>\r\n\r\n\r\n\r\n

Another appropriate rotary drilling bit is PCD(poly crystalline diamond) embedded mining bit. Unlike roller cone drills, PDC drills belong to a sort of fix-cutter drag bit since they don\u2019t have rotating cones and have to operate as a solid unit. All cutting movement is achieved in form of scraping materials by artificial diamond compact in various patterns. The diamond is sinterred into to a carbide matrix to form a integrated substrate. Admittedly PDC mining bits are capable of drilling stratum in compact strength less than 18000PSI and rock abrasiveness less than 41\u00b0. which means they are quite suitable for dealing with soft to medium hard materials, such as halite, gypsum, marlstone, limestone.<\/p>\r\n\r\n\r\n\r\n

You should learn about mining inserts and various mining bits tipped with them, whether you work for crude&gas industry, mining industry, or construction. I can see why it comes cause you realize works in these industries, more knowledge of tools you obtain, less hazardous condition and risk your guys will confront. As a manufacturer with exportation of mining tips gradually taking up one fourth of our whole annual throughput, we are thrilled to write this blog sharing some fundamental stuff about carbide mining tips that we are fabricating and familiar with. It couldn\u2019t be better if it assists in knowing the categories of drilling tips made of carbide and what…<\/p>","protected":false},"author":2,"featured_media":21891,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[107],"tags":[],"class_list":["post-21888","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-industrial-products-weekly"],"jetpack_featured_media_url":"https:\/\/www.meetyoucarbide.com\/wp-content\/uploads\/2023\/05\/u31150750051153150200fm253fmtautoapp138fJPEG.webp","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/posts\/21888","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/comments?post=21888"}],"version-history":[{"count":0,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/posts\/21888\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/media\/21891"}],"wp:attachment":[{"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/media?parent=21888"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/categories?post=21888"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/tags?post=21888"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
