down the hole hammer video

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.

The roller drill uses the rolling action of the roller bit to break the rock and is suitable for drilling holes of 150 ~ 440 mm in diameter on the hard rock. It has the advantages of high efficiency and low labor intensity, and is widely used in large and medium-sized open-pit metal mines. The drill consists of an impactor (or drill bit), a rotary mechanism, a lifting mechanism, a pressure device, a walking mechanism, a slag discharge system, a drill frame and a drill pipe. Rotary drilling machines are only suitable for drilling softer minerals and coal.

La innovación en los materiales y procesos de fabricación también ha impactado en el desarrollo de chocks para laminadores. Hoy en día, se utilizan aleaciones de alta resistencia y tecnologías avanzadas de fabricación para producir chocks más duraderos y eficientes. Esto no solo mejora la vida útil de los chocks, sino que también contribuye a la sostenibilidad de los procesos industriales al reducir la necesidad de reemplazos frecuentes.
