Research on a coal gangue identification device Zheng Gangfeng1,a, Zha Jiawei2,b, Liu Haizeng3,c and Li Ling4,d 1,2,3,4College of Materials Science and Engineering, Anhui University of Science and Technology, Anhui Huainan 232001, China agfzheng@aust.edu.cn, bjwzha@aust.edu.cn, chzliu@aust.edu.cn, dlingli@aust.edu.cn Keywords: gangue separation; automatic separation; grayscale sensor; guide groove Abstract: The paper designed a coal gangue identification device.
Compared with other separation device, it firstly put forward solutions to realize the linear arrangement of materials, and solve the problem of removing the soft sundry after hand sorting.
Compared with other separation device, it first put forward solutions to realize the linear arrangement of materials, and solve the problem of removing the soft sundry after hand sorting.
Of which the guide groove 1 can realize the linear arrangement of materials, grayscale sensor 3 can gain the gray signal of the material.

The prediction model of chemical shrinkage of cement based materials was established.
But the incorporation of admixture could change the hydration process of cementitious materials in some extent, and the chemical shrinkage will different.
Japan Concrete Institute [3] and American Society for Testing and Materials [4] had presented respectively the test method, but the rigid glass jar that they used had the restraint to the contraction of the test sample, and had certain influence on the test results.
The sample was loaded into the flexible plastic bottle and separated from the wall of jar made of the rigid materials in this device, so the volume change of sample was not restricted by the bottle wall and the surrounding rigid materials, and using colorful liquid not dissolved in water instead of paraffin to seal avoided the influences of the upper air pressure change on the test results, and the volume changes of cement paste could be reflected accurately by rising or falling of the liquid level in the burette.
