High speed rotating centrifugal atomizer is the key part in the flue gas processing. The different driving form affects the atomizer's stability of high speed movement, atomization effect and the ...running life directly. For a long time, the transmission quality of belt drive or direct coupling drive is one of the focus issues. Based on the high speed centrifugal atomizer, this paper introduces the two commonly used driving forms of the atomizer, and compares their performance through the experiments.

Abstract
CuIn1-xGaxS2 (CIGS) nanocrystals (NCs) were synthesized by a heating method. Lattice structure and optical properties of the samples were measured by X-ray diffraction, ...absorption spectroscopy, transmission electron microscopy (TEM) and Raman spectroscopy. X-ray diffraction results showed that the CIGS NCs have chalcopyrite structure, and theirlattice constant was related to the molar ratio of Ga in the NCs. The higher the molar ratio of Ga, the smaller the lattice constant. The size of the NCs was confirmed to be about 15 nm by X-ray diffraction and TEM. The energy gap of the NCs determined by absorption spectra was between 1.05 to 1.72 eV. Results of absorption measurement also showed that the energy gap was a quadratic function of the mole ratio of Ga. The higher the molar ratio of Ga, the larger the energy gap. The results of Raman spectroscopy showed that the main vibration signal of the CIGS NCs shifted from 178 cm-1 to 186 cm-1 as the molar ratio of Ga increased. The frequ
