The NG-250 confined pipe sampling machine designed and manufactured by Zhuzhou Coal Preparation Plant for automatic sampling of slime water pipes not only saves labor, but also eliminates human interference and improves the representativeness of samples. Has been used for more than two years, the effect is better. First, the structure and working principle MG-250 automatic sampling machine can be installed anywhere in the pipeline, coal preparation plant coal slurry sampling points for the rational arrangement provides the favorable conditions, the structure shown in Figure 1.
