mobile screw compressor

The term 185% compressors generally refers to portable air compressors that deliver high-performance output, typically rated at 185 cubic feet per minute (CFM). These compressors are designed for heavy-duty applications, making them ideal for construction sites, road works, and renovation projects. The 185% often signifies their exceptional performance relative to their size and fuel efficiency, underscoring their ability to deliver more compressed air than standard compressors within the same category.

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.

  • 1.Downhole drilling machine: When drilling a downhole gun hole with a aperture less than 150 mm, in addition to the application of a rock drill, it can also be used to drill a small diameter of 80 ~ 150 mm. When drilling a gun hole with a diameter of less than 70 mm in coal or softer mineral rock, it is generally used to drill or air drill, driven by a motor (or air motor) to drill the drill pipe, and the rock (coal) chips drilled out are discharged through the spiral groove on the drill pipe.
