Recently, we have upgraded the CSRC-500 by replacing the brands of key components to improve performance. The rotary sampler adopts a design similar to Atlas and is integrated on the top of the drilling rig. The slag discharge pipeline of the power head is thickened and the diameter is expanded. Special steel is used, and the service life is extended by more than 10 times, reducing the risk of slag blocking and enhancing the performance and reliability of the equipment. Welcome to consult!
