Abstract:

Purpose. Performing full-scale pilot testing of a complex of equipment on the basis of an experimental-industrial installation for the gravitational processing of granular minerals with the organization of a closed cycle of water supply.

Methodology. Standard methods of experimentation with experimental and industrial washing of sand of different granulometric composition with different settings of equipment complex are applied.

Findings. A description of the complex of equipment within the experimental-industrial installation for gravitational processing of granular materials, structures of decanters with pumping and pipeline equipment for the closed water supply cycle is carried out. A description of the processes that accompany the gravitational washing of the original granular raw materials with the specified non-standard innovative equipment is carried out. The list of standard testing and measuring equipment is given. A description of the methodology for industrial testing of the complex, which involves washing of different types and compositions of granular materials, using different settings of the equipment, in order to determine the rational technological and mode parameters of the washing equipment is given. At the initial stage of the research, a trial run of the elements of the complex was performed in order to determine the possibility of uninterrupted and safe operation of the systems, to check the tightness of the hydraulic system, to adjust the mode parameters when supplying the input granular material. Experimental-industrial tests of the complex were carried out in four stages, while washing construction sands of different compositions from Buriakivske and Veliunske fields.

Originality. Innovative technology of gravitational processing of granular materials was developed and tested for the first time, it provides for the possibility of changing the settings when feeding raw materials of different composition to obtain quality construction sand.

Practical value. The experimental and industrial tests of the complex of sand processing equipment allowed testing the system of circulating water supply and substantiating the technological rationality of its application both for water cleaning and for its ­supply.
