Abstract
The separated particle charge multivariate analysis instrument includes a transparent sealed container and, inside the transparent sealed container, an axial fan, a tube carrier plate, a rail board, double screw shafts, a biaxial motor, parallel electrode plates and so on. The separated particle charge multivariate analysis instrument of the present invention measures out the charge amount of the particle after leaving the particle bed by simulating a controllable environmental factor in the transparent sealed container on the basis of the inner tube, the outer tube, the electrometer and the charge amount of the particle entering into the inner tube at the measurement site, and analyzes effects of environmental factors, particle physical parameters and geometric parameters to the charge by adjusting environmental variables in the transparent sealed container.
