Mill equipment online analysis and diagnosis system is a fault diagnosis expert system based on knowledge, the main dynamic database, Engineering Analysis by Knowledge management, database management, knowledge base, database, inference engine, help and service, task management module components. 1. Knowledge Module: Knowledge is the fault diagnosis subsystem core ball mill, which is used to store all kinds of experts on the mill system fault diagnosis of experience and knowledge, a knowledge base of background knowledge, diagnostic knowledge, unit case file and run decision-making knowledge. 2. The database module includes the original data of vibration signals, spectrum and spectral array axis orbit and trends, trends characterizing mill operating characteristics of feature data, such as vibration signal amplitude of each frequency division and multiplication ceramic ball, slow varying signal in the steam temperature and pressure, temperature and lubricating oil pressure bearing pad, rotor displacement differential expansion and so on, these data reflect the mill equipment in the past, and now the state, but also indicates the future trend of development, is an important source of information for troubleshooting . Mill equipment is one of the main products Dahua Machinery Co., Dahua Machinery is the largest manufacturer and supplier of ball mill, located in the Central Plains, and convenient transportation, production quality assurance, and excellent service in the mill has a good reputation in the market. When the final result of the formation of iron strain fatigue in the material change occurs in the abrasive effect of the surface of the large ball mill equipment, the chiseling action occurs, forming a chisel cut pit, metal chisel out directly or plastically deformed, lining given force, squeeze the ball between mutual, failure is the main form of ball wear, broken and lost a round ball works, crushing and grinding efficiency reduces round loss, while accelerated wear of the ball, Under normal circumstances, the main reason for failure is worn, the primary mechanism Slag mill wear is: cutting and chiseling wear, surface of the ball can be decomposed into a force normal force and tangential force, and the ball relative movement sharp materials (abrasive) small ball at the normal force embedded surface, the tangential force is pushing the abrasive surface moving along, so that the ball low hardness abrasive scratches the surface of the shallow, high hardness is caused by abrasive cutting ditch. Wet ball mill, ball mill, Jieyang City, Dahua machinery provided by Gongyi City Dahua Machinery Co., Ltd. Gongyi City Dahua Machinery Co., Ltd. (www.dhqmj.com/) strong, credible, in Zhengzhou, Henan's industry-specific equipment industry has accumulated a large number of loyal customers.
