Information × Registration Number 0209U006439, 0106U001783 , R & D reports Title Development and researches a resource- and energysaving methods and facilities of a screening and dehydration of thin fractions of mineral resources on a sieve in essential a non-linear field of vibrational forces popup.stage_title Head Shevchenko G.O., Registration Date 16-02-2009 Organization Institute of Geotechnical mechanics named by N.S. Polyakov of NAS of Ukraine popup.description2 The physical model of a polyfrequency screen is built, the researches have allowed which one to establish nature of oscillations of sieves at regulation of parameters of operational mode and regularity of separation on fineness of aggregate and dehydration of thin fractions of mineral resources. The results of these researches have served as input datas for develop a mathematical model of a polyfrequency screen, the researches have allowed which one to establish parameters of oscillations of sieves, which one provide effective separation on fineness of aggregate and dehydration of thin fractions of mineral resources, and also increase of resource of sieves. By results of researches the methods of selection and calculation of the workers and dynamically parameters of polyfrequency screens are designed5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
