THE MATHEMATICAL MODEL OF THE PROCESS OF THE EXTRUSION OF THE HIGHLY FILLED PLASTICS ^{[№ 10 ' 2010]}
The authors examined the mathematical model of the process of the extrusion of the highly filled plastics with the use of methods of mathematical simulation, determined five parameters of the effect of process — productivity of press-extruder, power of the forces of useful resistance, effort, which acts on the operating units, pulse of the comprehensive compressive voltages, efficiencies of the single-screw pressing mechanism, making it possible to adequately estimate process extrusions.

DESIGNING OF FLAW OF MATERIAL OF HIGH TENACITY FOR RESEARCHING OF ITS QUALITIES AT HIGH SPEEDS OF SHIFT. ^{[№ 4 ' 2004]}
There is a shift of extrudable material with the high speed of shift in the cage of leakage of expeller in the process of work. Such speeds of shift are difficult to reach in capillar and rotational viscometers. The lack of facts about quality of materials of vegetative origin at high speeds of shift does not allow to calculate adequately consumable energy at its extrudition. The question of defining of tenacity by designing of flaw of materials in the cages of leakage is viewed.

MATERIAL RHEOLOGICAL PARAMETERS DETERMINATION BY MEANS OF REVERSE EXTRUSION IN CIRCULAR CHANNEL WITH A MOVABLE WALL. ^{[№ 3 ' 2000]}
The main power of useful resistance forces is spent in the run-off section. Therefore, optimization of the processes is needed to improve extruders single-screw pressed mechanisms used in food industry. It allows to determine rheological parameters of the extruded material in a thin layer with high speeds of the shift when it flows in circular channel (section) with a movable wall.

FEATURES OF THE AUGER PRESSING GEAR OIL PRESS ^{[№ 1 ' 1999]}
In the present article the mathematical model of flow of an oil-yielding material in the channel auger oil press is considered. The introduced model allows to define four arguments of effect - productivity of the pressing gear, power of forces of useful resistance, power consumption of process of squeezing and gain which is operational on end-effectors (axial force or a torque). The described mathematical model after its verification can be utilised for optimization of pressing gears at the stage of initial designing oil presses.
