The DTH hammer operates through a system of compressed air. High-pressure air is directed down the drill string, powering the hammer at the end of the drill bit. The hammer strikes the bit with considerable force, fracturing the rock immediately beneath it. As the bit penetrates further, the broken rock is then cleared from the hole by the same air stream, allowing for continuous drilling without the interruptions often associated with other drilling methods.

It is important to know that the shape of the sand has an important impact on the surface finish of the casting. Circular sand is better than triangular sand because the triangular sand has a large gap, which is easy to lead to defects such as porosity; According to the nature of the casting, the sodium silicate quartz sand is selected to form a spalling layer, and combined with the characteristics of cooling and shrinkage of the casting, the surface defects are reduced. Coating a protective layer on the surface of large castings, such as the film on a coated sand mold, can improve the surface finish of the sand mold and reduce the surface defects of the casting.

Drilling equipment is essential in various sectors, including oil and gas, mining, construction, and environmental research. Each sector requires specialized machinery capable of performing specific tasks effectively. For instance, in the oil and gas industry, rotary drill rigs and downhole drilling tools are critical for accessing subterranean resources. In contrast, the mining sector demands heavy-duty equipment designed to penetrate solid rock and extract valuable minerals.

Manganese is a critical element in the production of jaw plates, which are essential components in the mining and crushing industries. These plates are the main regions of contact in jaw crushers, which are widely used in the extraction and processing of raw materials. The importance of manganese in jaw plates cannot be overstated, as it significantly affects the durability, strength, and overall performance of the machinery.
