Theory and Practice of Functioning Machines for Vibratory Agitation

Abstract:

The article tackles a mechanism of vibration effect on the construction mixes in two representations: corpuscular and phenomenological. It is known that the construction mixes belong to heterogeneous systems, where processes take place in case of vibration effect that are characterized by tixotropy property, i.е. inversability of interaction forces between the particles in case of imposition and removal of mechanical effects. It has been stated that it is more reasonable to find the qualitative and quantitative relations of various processes (phenomena) in the form of generalized relationships obtained by the methods of similarity theory and dimensions of quantity. Presented are the criterial dependencies of changing efficient viscosity of mixes under effect of vibration from the process working parameters. Proposed are the modified Reynolds and Froude criteria for the mixes vibrating processes. It is reasonable to use the method of object internal vibratory protection when designing the vibratory agitation equipment helping reduce the level of vibration influence on the environment on the one hand, and use the vibratory effects on the material being processed to a maximum extent, on the other hand. In order to implement this method it is proposed to use the equalized eccentric vibration exciters. A number of industrial samples of vibration mixers have been presented.
