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.

Post-processing of large castings, large foundry processing manufacturers can use liquid sandblasting to clean the oxide scale and residue on the surface of the casting, which can not only remove impurities, but also play a role in polishing and improving the surface finish of the casting; Use grinding wheels, abrasive cloths, sandpaper and other abrasives to remove impurities such as burrs, protrusions and oxide scales on the surface of steel castings, so that the surface is smooth. In addition, methods such as mechanical, electrochemical and chemical polishing can further improve the gloss and corrosion resistance of castings.

In the mining sector, jaw crushers are extensively utilized for the primary reduction of various materials. These include limestone, granite, and ore, all of which are naturally tough and abrasive. The effectiveness of jaw plates made from manganese steel directly impacts the efficiency of the crushing process. A well-designed jaw plate can significantly reduce downtime caused by wear and tear, leading to increased productivity and lower operating costs for mining companies.
