A research group with Sin Tong Ho, a researcher at Faculty of Mining Engineering, as a leader has developed and introduced a vertical shafting air classifier equipped with a rotor cage with high classification efficiency and an assistant air pipe that makes it possible to realize accurate classification as well as to control classification size in the processes of dry fine grinding or microfine grinding-classification of fireproof material, chemical material, abrasive material, etc.
They selected a reasonable structure and made a hydrodynamic analysis of the motion characters of mineral particles in the rotor cage. On this basis, they made an optimal design of structural and operational parameters and put them on a scientific basis so that they could ensure needed particle size distribution of powder products and high productivity.
The feed size of this classifier is less than 0.1mm and its classification size is 10~74㎛.

From 17 to 19, November, the symposium was held under the sponsorship of the Central Committee of Korean Federation of Science and Technology, drawing scientists, technicians, teachers, postgraduate students, officials, etc. from scientific and educational institutions including
It was divided into 4 sections: artificial earth satellite, space materials and elements, space observation and basic sciences and applied technology, where 190-odd papers from various units were examined.
What attracted the attention of experts were those that gave a fresh solution to the pressing issues arising in further developing technologies of development, control, observation and communication of artificial earth satellites such as manufacturing and testing satellites and their parts, satellite navigation and orbit and attitude control, development of SAR and satellite camera, satellite communication, ground observation and development of various kinds of satellite materials.
“Ways To Extract and Improve Topographic Formlines by Digital Elevation Model” by Jong Hak Chol, a researcher at Faculty of Earth Science and Technology was considered to have a practical significance in surveying soil and forest resources, forecasting natural disasters, automatically detecting damaged areas, quantitatively deciding the extent of damage with the help of satellite data.
Besides, highly appraised were several suggestions including those by Kim Song Nam, a researcher at Faculty of Earth Science and Technology and Han Yong Su, a section head at Faculty of Physics Engineering.

Kim Myong Chol, teacher from Faculty of Heat Engineering succeeded in building and introducing a cogeneration power system, which can provide steam for production of higher pressure and raise the utility rate of energy to the maximum by the mode of combining electricity and heat.
He remodeled the ventilation part of bleeder condensing turbine in order to minimize the loss of effective work arising in steam depressing process for the supply of production steam.
Thus, he provided scientific and technological guarantee of saving natural resources of our country and supplying electricity and steam for production according to consumption process by raising the utility rate of energy in many factories and enterprises.
The pressure of production bleeder steam of the cogeneration system is 1MPa, the temperature of the steam is 270℃ and the amount of supply of steam for production is 0~30t/h.
