Hunan Minfeng South Cement Co., Ltd., which was established in 1958, is a state-owned cement factory with a long history and the first cement plant in Hunan. The first integrated electric down-the-hole drilling rig SWDA165 independently developed by Shanhe Intelligent has been responsible for the drilling and blasting construction of the mine since it entered the mine in 2005.

Walking in the roaring mine of the machine, in a world of yellow and gray-black, two beautiful mountains and rivers green, it is particularly eye-catching. Looking from a little further away, the two down-the-hole drilling rigs stood quietly on the construction site. They could not see the vibration of the fuselage, nor the roar of the machine. Only the drill pipe that kept rotating showed that these two The equipment is in working condition.

“The transformer and air compressor are designed in one piece, and the transition is convenient. It is enough to connect the wires during work.” Yang Kaiyang, director of the mine branch of Hunan Yufeng South Cement Co., Ltd., praised the integrated electric submersible drilling rig of Shanhe Intelligent. “We used to have six down-hole drilling rigs in our mine. Now we only have two of you.” From six to two, has the cement plant reduced production? But it’s not like looking at the smile of Yang’s factory manager! "Your DTH drills a top three! The six old equipments are now completely eliminated." Seeing us with a puzzled face, Director Yang explained.

Shanhe Intelligent's self-developed and produced down-the-hole drilling rig in 2003 integrates drilling, gas supply and power system. It has 21 authorized patents and 1 invention patent, which fills the domestic gap and its technical performance has reached domestic leading and international advanced level. When its first integrated electric down-the-hole drilling rig was launched in 2005, Hunan Jiufeng South Cement Co., Ltd. was preparing to upgrade the submersible drilling rig of the replacement mine. At the meeting, after a detailed understanding of the equipment, the cement factory purchased the SWDA165.

“Environmentally efficient, easy to change, easy to operate and maintain.” Yang Director summarized the trial results in three sentences. "In 2009, I bought another model of the same model and eliminated all the remaining three old machines. Others did not say that only one operator was operated, and four fewer. For more than ten years, Labor costs have saved at least 3 million."

According to the master of the machine, the first day of the equipment to the mine, he is a full-time machine, and dealing with this machine for 15 years, on the familiarity of the machine, no one can compare. "For 15 years, the machine has never had a big problem." Master Shi’s love for SWDA165 is beyond words. "The general dive hole drill used in eight or nine years, basically scrapped. This machine can now be a 18-meter deep drill hole in forty-five minutes." After 15 years of wind and rain The writing on the nameplate is illegible, but the performance of the down-the-hole rig has remained so good and amazing.

Director Yang said that because the requirements of environmental protection are becoming more and more strict, a large number of small cement plants that are not up to standard environmental protection have been shut down. The existing production capacity of Qifeng South Cement Co., Ltd. is not keeping up with market demand. The company plans to add a new one. The cement production line and a stone production line, together with the submerged hole drilling rig, will be seriously considered by the company. (This article comes from Shanhe Intelligent)
