Detailed Product Description: | We beneficiation equipment mill occupies an important position, and more ball mill model, due to the installation and manufacturing reasons, some concentrator mill has repeatedly appeared small ring gear tooth fracture and drum support tile damage accident, in order to avoid such accidents for the mill drive system status slag mill, vibration monitoring system was designed, Dahua mechanical failure for the users friends this example diagnostic analysis. I. Overview of ball mill belonging to the low-speed vibration monitoring, heavy equipment, mill equipment transmission by the drive motor, coupling, reducer, the size of the transmission gears, bearings and other components, ball mill drive train if there is poor lubrication, gear or bearing failure will result in abnormal vibrations, by monitoring the vibration signal characteristic parameters that can detect early failure of gears and bearings. Vibration Measurements of a ball mill monitoring system includes: an electric motor bearings at the measuring point; 2 reducer bearing at the measuring point; three sides pinion support bearing measuring points; 4 Shaft support bearing.... measuring point. www.zzyuxi.com two, vibration monitoring system hardware configuration mill equipment vibration frequency of the transmission parts, require low-frequency characteristics should have a good selection of vibration sensors on a ball mill and related equipment, and cover the high frequency data acquisition monitoring system installed In the vicinity of the ball mill, a fully enclosed chassis, data acquisition host moisture, dust, nearby monitoring equipment was installed in the industrial field, thus reducing the length of a weak signal transmission, prevent noise interference, improve the reliability of the monitoring system, data acquisition principles may consult Dahua Mechanical Technology Department, is responsible for the completion of field data collection powered sensor signal amplification, anti-aliasing filter, A / D converter, DSP chip data processing, digital signal acquisition to vibration through the network cable remote transferred to a dedicated control room monitoring computer for data display, analysis, alarm and storage. If the open mill equipment installation, electrical protective measures are not taken, prone to electrical short circuit, Dahua mechanical implementation of the control system installation program, and after repeated tuning PID ceramic ball, put into operation on the same day to obtain satisfactory results, from stable the amount of material occurs silo normal start, but the frequency modulation does not go up, ball mill drive to start, but the frequency of 20Hz when transferred from the stop trip, fault records show that "motor short circuit", with the shake table to measure the motor insulation is low, only 0.5 MQ cone ball mill, followed by welding processing power on 24 hours, insulation up to 10M (qualified), power-on test, the frequency of 30Hz transferred from the stop trip took place, still shows "motor short circuit" to open the motor star point resistance measurements and white, found U phase and W-phase phase short circuit occurs, replace the motor fault elimination. Failure Analysis: mill outdoor installation, improper scene rain measures before starting the rainfall, causing the motor damp, not dry motors that turn cause localized phase short circuit, our approach to occur: increased motor rain measures, strict testing before starting the motor insulation . 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. Wet ball mill _ _ Shiyan 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.
