Adjust the thickness of material on the grate bed.
Due to the material thickness of the grate bed is difficult to detect, Cement companies generally use to change the speed of the grate to adjust the material thickness of grate bed.
Interfering factors include flow rate of raw materials and the fall of kiln skin.

In recent years, with the development of high performance InGaAs diode and its reduced costs, laser materials doped have aroused considerablely interest in the study [2,3].
With the improvement of the LD pump power, the coating and laser technology, as well as the new types of Yb:YAG material preparation, Yb:YAG laser will make more progress.
Yb: YAG has long fluorescent life, more than three times in the same kinds of laser materials for the ion, and has ability to efficiently store energy.

Introduction Scanning electron microscope (SEM) is a powerful instrument for a high resolution imaging of materials from a various fields of science and industry.
Powder P47 and yttrium aluminium garnet (YAG) single crystal [7] are the most efficient scintillators even if powder material of P47 is suitable only for SE detectors.
Apart from the well known material contrast of the BSE micrographs, other advantages of the BSE detection mode were determined.
The above outlined properties demonstrate that the scintillation BSE detector is an excellent tool for the basic material characterization of both conductive and insulated nanomaterials.
