Coal Consistent Coefficient Of Automatic Detection Devices

As China's industrial development, it is increasing the demand for coal; Coal mining safety has become a major concern of social. Mining risk of underground coal mining are also increasingly prominent, consistent coefficient of coal seam is to determine key indicators highlight the dangerous one. Consistent coefficient of coal in the pit are generally not directly measured, but in the face of coal samples collected and sent to laboratories in accordance with industry standards with "drop hammer" were determined. Manual testing laboratory are now consistent coefficient of coal, labor-intensive and time-consuming. Now this method has been improved by adding some control to be automated.(1) On the basis of the analysis of the industry standard"drop hammer"measuring coal consistent coefficient.(2) According to "drop hammer" requirement, made a detailed design such as on the feeding mechanism, smashing equipment and screening coal plant coal.(3) Measuring device adopted the principle of differential transformer displacement measure the height of coal and making the circuit diagram of the device.(4) The external environment of a number of other factors on the robustness of the impact of coal and its development.
