6 FAQs about [Structure diagram of pneumatic rock drill]

What is a pneumatic rock drill?

A pneumatic rock drill is a kind of percussive drilling machine powered by compressed air. According to the propulsion mode, the equipment can be divided into handheld rock drilling equipment, air leg rock drilling, telescopic upward rock drill, and guide rail rock drilling machine.

What are the parts of a pneumatic drill?

A pneumatic drill consists of the diesel-powered air compressor, the outer casing, the handle, and the air inlet, and outlet valve. Inside the casing are tubes, a diaphragm valve, and the pile driver.

How much does a pneumatic rock drill weigh?

The pneumatic rock drill (American Pneumatic Tool, Model APT-115; 8.6 kg; 48 Hz percussion frequency) is toward the low end of the weight range of rock drills. For each study, the drills were fitted with new 19 mm diameter 2-carbide tipped bits of similar mass (Hilti TE-Y for the electric drill and Crowder WB77-750-14 for the pneumatic tool).

What is the noise level of a pneumatic rock drill?

A 1971 environmental noise survey in 21 coal mines by the Bureau of Mines revealed that pneumatic rock drilling for the installation of roof bolts exposed individuals to the highest sound levels observed, a range of 104 to 118 dbA (7). The pneumatic drill is used worldwide and in hard rock mining, comparable noise levels are common.
