METHOD FOR CONTROL TECHNICAL STATE AG MPS 180BK VERTICAL JAR ROLLER IN IT VIBRATION CHARACTERISTICS
Keywords:
vertical Jar roller, wear and tear, operating element, coal grinding process, wear and tear value control algorithmAbstract
Some theoretical backgrounds were considered, and practical algorithm of jar roller work surfaces state definition by measurement and analysis of vibration characteristics of coal milling process, is suggested. It is defined, that input milling material always have constant percentage of fragment size, which is stipulated by special technology coal preparation before milling, therefore in specific number of measurement along crack time big-size fragments vibration bump, we can calculate specific coal fragment number, from which any signals aren’t fixed by sensors, for it’s small “signal/noise” ratio. But we can define how many metal weight is destroyed in mill process
