In addition to the correct choice of carbide grade, the efficiency of rock drilling is influenced by many factors, mainly the shape of the drill head, the hardness of the rock, the compressed air pressure, the method of powder discharge, the diameter of the borehole and the depth of the borehole.

We started our first live broadcast in September at 23:00 on September 1st.

The DMiningwell crawler water well drilling rig MW series is a highly efficient and reliable piece of equipment designed for a wide range of applications.

Comprehensive use of air compressors

The working principle of piston air compressor is a fascinating blend of mechanical precision and efficient energy conversion. Piston air compressors operate by using a reciprocating piston to compress air within a cylinder. As the piston moves down, it draws in air from the atmosphere. Then, as the piston moves up, it compresses the air, increasing its pressure. This compressed air is then stored in a tank for use in various applications.
This reliable working principle makes piston air compressors a popular choice for industries such as manufacturing, construction, and automotive.

In the context of the continued development of the global water well drilling rig market, the MWT series of truck-mounted water well drilling rigs launched by D Miningwell is becoming the focus of the industry with its excellent performance and wide applicability.

Dminingwell make steel for DTH hammers and bits, which is sole in China. All products are under strict quality control and inspection, there are 8 times heat treatment operations to ensure the ideal hardness of our products.
During this visit to the factory, we also found that Dminingwell has a special workshop to recycle scrap steel and reuse it through high-temperature forging. At the scene, we can see a huge pliers clamp the hot steel and beat it, and then use the crane to put the beaten steel in the pearl sand to keep warm. Manager Zeng said that they have many raw material manufacturers with good relations. They have large and stable purchase quantity from them and they guarantee to supply stable quality material to us.

Precautions for using the DTH hammer
