Automatic control of jet grinding on the basis of acoustic monitoring of mill operating zones

Purpose. Increasing the jet mill productivity by use of automatic control grinding chamber filling level based on acoustic monitoring results process. Methodology. Simulation is performed in MATLAB. Acoustic signals operating zones are used to determine process parameters. Findings. A simulation model system created, which takes into account inertia material flows and classifier, as well main disturbing influences forming output flow. To analyze process, there three parts information component (regulator technical means automation), a set mathematical models that describe physical processes classifier. study made under condition determining controlled value indirectly through spectral analysis signal mill. The insignificant influence perturbations quantity due very slow with comparison period stream fluctuations at entrance owing perturbation action shown. Originality. For first time possibility has been proved using relay regulator filling, determined efficiency operation according law investigated. Practical value. It shown transition from automated increases 1015%. obtained build control.
