Skrypyuk R. The vertical roll mill technical state control

The different kinds of mills technical state control known methods are analysed in presented work in context of one's possible using to investigate the vertical roll mills (VRM) technical state. The considering methods boundedness to solve the VRM diagnostics problem are showed, the parametric and vibroacoustic diagnostics methods using possibility are grounded both with the object's identification methods using transfer characteristics to solve the put by problems. The VRM working body wear and tear and the coal grinding process correlation analytical investigation are conducted, the VRM generalized model are designed. The experimental investigation software, device and manual are designed. The VRM technical state control method based on the one's vibration characteristics is designed. The VRM state diagnostic features are defined based on the transfer characteristics parametric identification method using the P3ZU model Tp3 parameter, the autoregression model pole value, the spectrum amplitude on the 25 and 15 Hertz, which was determined by the non-parametric diagnostics method. The VRM diagnostic microcontroller system is designed both with one's software, the designed system error calculation was made, the one's value is 1,811%, it was established that the diagnostics period equal 4 days and nights if the readiness index is equal 0,96. The VRM working body technical state control designed methods industrial approbation was made on the "Ivano-Frankivskcement" Company.
