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.

One of the most critical components of a jaw crusher is the jaw plates. These are the surfaces that come into direct contact with the material being crushed. They typically come in two varieties the fixed jaw plate and the movable jaw plate. The fixed jaw plate is stationary and mounted on the frame, while the movable jaw plate moves back and forth, creating a crushing motion. The wear and tear of jaw plates are significant since they constantly encounter abrasive materials. Hence, they are often manufactured from high-grade manganese steel to enhance their durability.

At its core, submarine hammer drilling employs a powerful hammer mechanism to drive a drill bit into the seabed. The system utilizes both air and water pressure to deliver repeated impacts on the drill bit, which enables it to break through hard rock formations or sediments that might hinder installation efforts for marine infrastructure. The design of the hammer ensures that the energy is efficiently transmitted to the drill bit, allowing it to operate at significant depths.

  • PVC ceiling grids are lightweight frameworks that support ceiling tiles or panels made from polyvinyl chloride (PVC). They are designed to create a suspended ceiling system, which is an increasingly popular choice among architects and interior designers. The grids typically consist of various components, including main runners, cross tees, and wall angles, which collectively hold the ceiling tiles in place.


  • Understanding and adhering to proper T-bar ceiling grid dimensions is critical for several reasons. First and foremost, it ensures a cohesive and professional appearance. Incorrectly sized grids can lead to uneven tile fitting, resulting in gaps or misalignments that detract from the overall look of the ceiling.
