Визначення параметрів процесу транспортування та змішування кормових сумішей на криволінійних трасах трубчатих конвеєрів

The results of theoretical and experimental studies of simultaneous transporting and mixing the components of feed mixtures along the curvilinear paths of tubular conveyors are presented in this article. A mathematical model of the dependence of the change of elementary work performed while transporting the bulk material elementary mass along the curvilinear section is developed. Based on experimental researches, the technique of determining the technological parameters, which ensure the reduction of energy consumption while mixing bulk materials with the given quality of feed mixtures, is proposed. When considering the range of changes in the inner holes of the washers dh = 14…25 mm and the angles of their position to the horizon = 30°…75°, the intensity of the material components passing-through and their consequent mixing increases with the increase of the value of the parameter dh and the reduction of the angle

Математична модель згинних коливань горизонтального завантажувача-змішувача вздовж потоку зернової суміші

During the grain mixture motion along the working body of the feeder, the transverse (bending) vibrations occur. To deduce a differential equation describing bending vibrations of the feeder-mixer horizontal screw, a physical model is developed; the distribution of forces acting on the element of the horizontal working body during the grain mixture movement is defined

Вплив потоку сипкого матеріалу на техніко-економічні показники роботи гвинтового конвеєра

The paper covers theoretical investigations of the movement of bulk material flow when it is fed by a pneumatic screw conveyor. Process calculation of the impact of bulk material particles during their transportation in guiding covers has been conducted. A mathematical model, which characterizes the overall energy spent on the impact of two particles, depending on impact velocity, physical and mechanical properties of bodies and impact conditions, has been developed. The limits of design and kinematic parameters that provide the effective application of pneumatic screw conveyors for transporting bulk materials have been defined
