RESEACHING DEVICES VITH MAGNETTICALLY FLUIDIZED LAYERS
The researching results of direct current (DC) electromagnetic choppers, electromagnetic mechanical actuators, electromagnetic stirrers and electromagnetic densitometers for control of technological enviroment pollution with ferroimpurities are generalized. Function of these devices is based on nontraditional method of transmitting mechanical energy to grinding elements layer using quasi-stationary DC magnetic field. Method of culculating the magnetic fields stadied devices is based on induction of secondary sources end consists of reducing the problem to integral equations with their numerical solution. The method of integral equations allows us to construct the magnetic field in working volume (gaps) of cilindrical structure apparatus with an electromagnetic method of forming the bonding efforts and determine the parameters of the field (indaction and tension) at any given point of working volume in which the contact force between the ferromagnetic particles efforts (the grinding bodies or ferroimpurities) in their magnetically fluidized layer is implemented.
