GW&P: Lesson 18 Methods for Constructing Deep Wells

This method of drilling coines the percussion effect of cast tool drilling and the rotary action of rotary drilling. It is also known as ‘Rotary-cum-Hammer drilling’. It uses compressed air as the drilling fluid which provides the fastest method for drilling in hard-rock formations (Todd, 1980); it can drill 15-20 cm holes to a depth of 120 m in 10-15 hours (Raghunath, 2007).

Rotary Valves for Bulk Material Processing | ACS Valves - What …

25/5/2016· One of the ways to do this is by using an isolation device—such as a rotary airlock valve. Just to be clear—an isolation device won’t prevent and protect against deflagration in your system. Prevention means eliminating any ignition sources in your machinery and your plant that could lead to deflagration.
