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

All mining tips are designed for ensuring\u00a0themself\u00a0as durable as possible regardless of the rock and dribs\u00a0involved.\u00a0whether made of pure WC-Co carbide or sintered polycrystalline diamond&carbide compact,\u00a0they are both characterized by their unique particle size and distribution of Co atoms offering themselves outstanding abrasion resistance, compact toughness, and the foremost stiffness against heat deformation.<\/p>\r\n\r\n\r\n\r\n

Tane b\u00fcy\u00fckl\u00fc\u011f\u00fc:<\/strong>\u00a0In contrast with\u00a0powders of carbide cutting tools, those of mining inserts are supposed to be as big as possible which normally\u00a0reach up to from 0.4\u03bcm to 3.5\u03bcm in diameter. 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

There are 3 types of carbide drill heads on percussion rock mining bit available in our store, showed in the picture.<\/p>\r\n\r\n\r\n\r\n

Differing from percussion bits,\u00a0rotary rock drill burrow itself into earth\u2019s face relying on its cutting edge, where rocks get by rotary toque and longitudinal thrust. There are cone drill, coal electric jackdrill, coal cutting pick, rock core drill, and TBM scraper blade falling into this category.<\/p>\r\n\r\n\r\n\r\n

In most time, carbide tips with high toughness and hardness are adopted on cone bits. \u00a0These tips are devised in different shapes (showed as below) in order to gain prominent cutting ability. A layer of wear-resisting hardfacing covers the whole bit body for high wear resistance and prolonged tool life.<\/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

There are two common types of existence of PDC mining bits,<\/p>\r\n\r\n\r\n\r\n

Elbette \u00fczerlerinde giyilebilir bir sert kaplama ile korunuyorlar. \u00a0<\/p>\r\n

Bundan sonra, uygun kalitede karb\u00fcr madencili\u011fi u\u00e7lar\u0131 se\u00e7me ilkesi gelir. Son derece sert kayalar\u0131n delinmesi ve k\u0131r\u0131lmas\u0131 ile ilgili olarak, a\u011f\u0131r i\u015f delme makinelerinde g\u00fc\u00e7l\u00fc sertlik gereklidir. Bu nedenle, yaln\u0131zca y\u00fcksek kobalt i\u00e7eri\u011fine sahip karb\u00fcr karb\u00fcrler uygundur. Sert ve k\u0131r\u0131lgan kayalar veya g\u00fc\u00e7l\u00fc a\u015f\u0131nd\u0131r\u0131c\u0131l\u0131\u011fa sahip malzemeler i\u00e7in, d\u00fc\u015f\u00fck kobalt i\u00e7erikli sinterlenmi\u015f karb\u00fcr kaliteleri se\u00e7ilmelidir.<\/p>\r\n\r\n\r\n\r\n
