A well-known grinding drill bit technology that you have to know
Written by Simon from Prodrill on Jun.30,2017
Grinding drill bit is a special industry in foreign mining and mining industry. In domestic mines, few people know how to grind, Drill bit is a disposable consumption, scrapped with one time, obviously, it is the waste of drilling tool resources.
In recent years, With the awareness of environmental protection, resource recovery and energy saving in mining has been improved. The mine user can also make full use of the bit grinding system to make the drilling efficiency of the heavy l open pit drilling vehicle, the underground driving trolley and the DTH drilling rig more efficient. Both CME and Atlas Copco can supply advanced grinding equipments.
Atlas Copco Corokundefineds latest DTH drilling rig is the Qind Matic BO2 type. This new semi-automatic drilling rig can use DTH hammer and bit with spherical and ballistic column teeth.
The assembled device includes automatic central support arm. Split bit gripper and high power grinding machine with rotating speed up to 14900 r/min.
The improved spindle makes the replacement of grinding wheel faster and easier, and the time relay, tilting bit holder and electrical locking device enhance the variety of the grinding machine. This kind of grinding machine can repair the drill bit with maximum height of 650 mm, maximum diameter of 178mm.
However, The procurement and maintenance cost of above grinding machine system is very high in view of the current drilling and production market demand, We have developed a hand-held pneumatic grinding machine (grinder), It is more suitable for the current domestic mining drill bit grinding in respect to the economy, maneuverability, mobility or simplicity.
In addition, we also provide international standard grinding cup series, which can completely replace the imported type of CME, ATLAS, SANDVIK and KING. At present, a large number of it has been exported to major foreign mining countries,such as: Australia, Spain, Chile, India, etc., and has received good reputation by the mine owners!
When quote the price, A businessman should pay attention to the following points so as it can help you get the order quickly:
1.Type and series that the customer request
2.Size and shape
3.To realize the height of the exposed surface of the diamond bit in production. The exported bit will be higher than the domestic bitcompare with the height of the exposed surface, It is obvious that the exposed part will be higher so that it is convenient to grind the bit after working.
