class=\"wp-block-heading\">Core Advantages of Reverse Circulation Drilling Rig<\/h2>\n\n\n\n<p class=\"has-medium-font-size\"><strong>1.<\/strong> <strong>Efficient Drilling &amp; Low Energy Loss<\/strong><\/p>\n\n\n\n<p class=\"has-medium-font-size\">Equipped with a special reverse circulation impactor, energy transfer efficiency is effectively improved, and daily drilling depth can reach around 200-300 meters. Strong chip removal capability helps reduce the probability of in-hole accidents by a large margin, keeping continuous construction stable.<\/p>\n\n\n\n<p class=\"has-medium-font-size\"><strong>2.<\/strong> <strong>High-Sample Quality &amp; Blockage Resistance<\/strong><\/p>\n\n\n\n<p class=\"has-medium-font-size\">Rock and mineral samples can maintain a high collection rate with no pollution. When drilling in clay formations, the matching hole cleaning device can solve inner pipe blockage in a short time, and the smooth operation rate of drilling is effectively improved.<\/p>\n\n\n\n<p class=\"has-medium-font-size\"><strong>3.<\/strong> <strong>Full Hydraulic Control &amp; Labor Reduction<\/strong><\/p>\n\n\n\n<p class=\"has-medium-font-size\">All machine actions are driven by a hydraulic system, with a maximum rotation torque covering 8000-24000Nm to adapt to different strata. This design can effectively reduce manual operation intensity, and the efficiency of drill pipe connection and disconnection is increased by a considerable extent.<\/p>\n\n\n\n<p class=\"has-medium-font-size\"><strong>4.<\/strong> <strong>Environmentally Friendly Construction<\/strong><\/p>\n\n\n\n<p class=\"has-medium-font-size\">The supporting dust removal system can collect more than 90% of drilling dust, and the cyclone separator can accurately separate slag for sampling. The whole construction process meets most regional environmental protection standards, with low on-site pollution.<\/p>\n\n\n\n<p class=\"has-medium-font-size\"><strong>5.<\/strong> <strong>Stable &amp; Precise Operation<\/strong><\/p>\n\n\n\n<p class=\"has-medium-font-size\">With a drill tool centralizer and level gauge, the accuracy of hole initiation is effectively guaranteed. The drill frame supports construction within an angle range of about -10\u00b0 to 90\u00b0, and the outrigger stroke is around 1.6-1.7m, which enhances the overall stability of the equipment during operation.<\/p>\n\n\n\n<p class=\"has-medium-font-size\"><strong>6.<\/strong> <strong>Component Protection &amp; Durable Performance<\/strong><\/p>\n\n\n\n<p class=\"has-medium-font-size\">The patented air pre-filter can filter out over 90% of intake dust and realize automatic discharge, reducing the wear of engine related parts. The enlarged inner tube of the double-wall drill pipe improves the return efficiency of deep-hole rock samples, and the threaded casing saves on-site construction time effectively.<\/p>\n\n\n\n<p
