Cadastre of Scientific and Technical Developments

1. Main ways of activity.

Subjects:

The development and production of new efficient systems for fragmentation-pounding, disintegration-activation, dispersion-drying,husking-grinding, separation-classification of materials with a wide range of viscosity and toughness, including raw agricultural materials, industrial, domestic and agricultural wastes, pounding of coal, rubber-polymeric, building and other  materials.

The production of dispersed composites with necessary qualities (powders, pastes, suspensions) with the help of methods of dispersion technology prctically from any initial materials.

Basic principles:

        Processing characteristics of powder depend not only on its size but to greater extend on the structural internal performance and the state of the surface, physic-chemical conditions of the powder production determine these qualities. Therefore using developed methods of pounding-activation powders of high quality can be produced.

        The work on the theory of the process of pounding-activation of materials done in our Institute allowed work out on its basis new hardware which have a simple costruction, low metall-consumption, economical efficiency. Such qualities allow to pound practically any material, powder and suspensions with the size of its particales of the micron spectrum. Made on the basis of many years researches the new generation of energy-economy methods and machines for the pounding-activation, disintegration-spraying, separation and classification of fine and granular materials allow to establish an industrial production of efficient and competitive machines with a wide range of application and to develop new technologies and materials. It allows to:

- to pund and activate materials with a wide range of physico-mechanica qualities (friable, solid, visco-elastic and viscous-plastic, including metals, oxides, nitrides, quartz, coal, plastics) up to necessary quality and dispersibility and to produce activated powders with a high reactivity;

-  to spray and disperse different substances - from soild to viscous-plastic, from quartz to bitumen including melts. Plant are easy to operate with and allow to adjust the size of the sprayed particles up to 1 - 50 micrimicron. It in its turn allows to produce powders from melts with the necessary quality, to dry viscous and paste-like materials with the sprayin drying;

-  to separate substances (over micron range of sizes) according to its size, density, and to classify coarsely dispersed materials with different humidity. Systems are precise in separation and have high specific capacity.

The physic basis  of new principles of pounding-dispersion is the metastable local thermodeformation model of a phase transformation by destruction in the process of pounding-activation-dispersion according to which to one unit of vloume of the material under the process of pounding there should be brought the necesary amount of energy of the given intensity which is determined by the vector of the power flux density.

The engineering basis for the development of the hardware is the creation of shear forces of the necessary intensity in the volume of the material under grinding, and the combination and diversion of the grinded material. There have been made plants with 2 techniques for the creation of pressure:

        1. a hydrostatic method (an isothermal process). By this method the high pressure (more than 5.10^s pascal) is combined with a low speed of deformation;

        2. a centrifugally-dynamic method (an adiabatic process). Here a low pressure is combined with a high rate of deformation.

The three-dimensional self-grinding, used in the basic machines, provides with a high efficiency of the process and simplify problems of ranging by the developing of plants with a greater specific capacity. The possibilty of creating different shear deformations and pressures in the developed mechanisms predetermines a hugh efficiency of the processes of the meterials processing in a wide range of physico-mechanical properties.

It should be mentioned that the developed method of grinding with the help of the shear in the field of omnidirectional tension is a new method. Thus the mill constructed on this method efficiently crushes and disperses - sprays materials with different physico-mechanical qualities and allows to produce pure powders.
