Demand Market and Maintenance of DTH Bits
2022-07-08
Where is the demand market and direction of DTH drill bits? With the continuous rise of fuel prices, the operating efficiency of construction machinery has become a very important indicator in engineering projects. The selection of high-efficiency rock drilling machinery requires the configuration of high-quality and efficient rock drilling tools. In order to improve the drilling efficiency of the drilling tool and the service life of the drill bit, the research and development team with a large number of instruments also made some adjustments to the structure of the medium and high pressure down-the-hole drill bit, such as some adjustments to the tooth structure of the column teeth on the end face of the drill bit.
Hot spot of the week! What are the major global mining events this week?

The main mining-related contents are as follows: first, by 2025, the energy efficiency of key products in iron and steel, petrochemical, non-ferrous metals and other industries should reach the international advanced level, and the energy consumption per unit added value of industries above scale will be reduced by 13.5 compared with 2020. Second, we should deeply tap the energy-saving potential of iron and steel, petrochemical, non-ferrous metals and other industries, promote the upgrading of technology and process in an orderly manner, promote the level of energy efficiency, and achieve steady improvement of industry energy efficiency. The third is to accelerate the innovation and upgrading of key materials such as high-performance magnet wire, rare earth permanent magnet, high magnetic induction and low loss cold-rolled silicon steel sheet. Fourth, in accordance with the principle of "gas-based reform" to promote industrial coal-fired natural gas substitution in an orderly manner.
Preparation method and process of drill bit

The cross drill bit has four drill bits arranged in a cross. Under the condition of rock drilling with large impact power, it is used to excavate fractured rock layers and rock layers with strong wear resistance. However, the cross drill bit has strong radial wear resistance, and when drilling rock, the gap of the drill bit is easy to block stones and the drilling efficiency is low. Then, let's learn about the preparation method and process of the lower drill bit together!
Structural Characteristics and Mining Application Analysis of Different Types of Drill
2022-07-04
Coal mine production and tunnel construction need to excavate rock stratum, but with the application of hydraulic rock drill in the excavation process, the cross-sectional area and length of the drill bit increase, and its working situation is becoming more and more complex, which limits the different structure and application scope of the drill bit in the application. Therefore, reasonable drill bit must be used in the application to ensure the smooth construction, especially the development of composite drill bit promotes the development of the device, let's learn about the structural characteristics of different types of drill bits and the analysis of mining applications!
Matters needing attention in the process of using the drill
2022-06-28
In order to reduce the energy reflection when drilling soft rock, it is necessary to reduce the impact pressure or energy. The greater the given impact pressure, the greater the stress in the drill segment. In order to make the service life of the drilling tool and the drill tail as long as possible, it is necessary to ensure that the working pressure always matches the drill chain.

Speaking of the drill, there will certainly be a lot of people do not know this product. In fact, it is the same. Only people in the mining industry will know this product well. This is a kind of equipment specially used in the mining industry, and drilling tools are one of the common types. So what are the characteristics of this product?
