3. Open-air drilling rig: according to the different working mechanism of crushing ore and rock, it is divided into steel rope percussion drill, drilling rig, cone drill and rotary drill. Because of low efficiency, the steel rope percussion drill has been gradually replaced by other drilling RIGS. The drill pipe drives the pneumatic impactor and the drill bit to rotate together, and the piston of the pneumatic impactor is used to impact the drill bit to break the ore and rock, which is usually used in small and medium-sized mines to drill holes with a diameter of 80 to 250 mm.

The specifications of a drilling machine significantly affect its price. Machines with higher power ratings, precision controls, advanced technology, and additional features such as automatic feed, depth control, and multiple drill bit sizes usually come at a premium. For example, CNC (Computer Numerical Control) drilling machines offer unparalleled precision and automation, making them highly sought after in manufacturing environments, but they can carry a price tag in the range of $100,000 to $500,000, depending on the specifications.

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.

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.
