Provided range of automatic Sampling Unit has extensive applications in power generation plants and mining field. This unit can be installed in an existing conveyor for examining and analyzing different properties of minerals like limestone, coal and dolomite from movable conveyor belt. Sampling Unit tends to move in perpendicular direction to the flow of minerals moved by conveyor. Sample of mineral is automatically thrown into its chute. Advanced analysis system is used to collect sample from chute. Rotational speed of its sample scoop depends on the operating speed of conveyor belt. Electrically actuated structure, dirt and water proof design are some of its main features.
