Original Title: Continuation of Classics | 50-90MM Small Aperture Top Hammer Drilling Rig Attacks Efficiently! Kong Shan added another fierce general. KS680 Top Hammer drill Relying on technological innovation and local market demand, Kongshan Heavy Industry has integrated advanced and reliable design concepts of drilling rigs for more than 18 years, and devoted itself to the development and launch of KS680 top-hammer drilling rig to meet the needs of users with flexibility, convenience, high efficiency, energy saving and environmental protection! It is the hard core of rock drilling in narrow environment and rugged working conditions such as subway, foundation pit and tunnel. What is the difference between a top-hammer drill and a down-the-hole drill? 01 The impact mechanism of the down-the-hole drill is at the bottom of the hole, and the impact power is directly applied to the tail of the drill bit, so it is called down-the-hole drill. The percussive mechanism of the top-hammer drill is at the bottom of the hole, and the percussive power acts on the top of the drill rod, so it is called top-hammer drill. 02 The down-the-hole drill uses a high air pressure air compressor and is equipped with a down-the-hole drill bit at the drill bit position, which is suitable for hard rock above 200 MPa. The top-hammer type drilling machine uses the medium and low wind air compressor; the rock drill on the top of the drilling frame is used for operation. It is more suitable for rock operation with hardness below 200 MPa. 03 The hole diameter of the down-the-hole drill is more than 105mm, which is larger than that of the top-hammer drill, and the hole depth is 10-45m, dth drilling hammer , so the efficiency of using the down-the-hole hammer is high! The hole diameter of top-hammer drilling machine is less than 127mm, and the hole depth is usually not more than 20m. When the hole depth is about 15m, the top-hammer drilling efficiency is relatively high! Conclusion: The two kinds of drilling rigs have their own advantages, and only by selecting the appropriate equipment under the appropriate working conditions, can the greater economic benefits and the minimum operating costs be achieved. Next, let's take a look at what the KS680 top hammer drilling rig is superior to others!
