GE3000 CM
The system enables the measurement of the coal calorific value directly on the belt conveyer using the combination of radiometric ash content measurement and microwave moisture measurement.
Application field：The detection frames can be placed in a different way depending on its use and coal parameters. In the basic configuration both of the frames are placed directly on the belt conveyer. In case that the coal layer or coal granularity is not suitable for the moisture measurement, the system should be placed near the sampler and the moisture measurement frame should be placed at the crushed coal sample transport system. Such design can be used almost for any kind of coal in case of suitable sampler setup.
