Bearing overheating analysis:
Bearing is a more important part of the universal dust removal crusher, and its performance directly affects the normal operation and production efficiency of the equipment. During the operation of the equipment, the user should pay special attention to the temperature rise of the bearing and the noise of the bearing part, and the abnormal should be dealt with as early as possible.
(1) The two bearing seats are uneven, or the motor rotor is different from the grinder rotor, which will cause the bearing to be impacted by additional load, resulting in overheating of the bearing. In this case, it is necessary to immediately stop using the universal crusher for troubleshooting to avoid early bearing damage.
(2) too much lubricating oil in the bearing, too little or aging is also the main cause of overheating and damage to the bearing, therefore, according to the requirements of the use of the book on time and quantitative filling of lubricating oil, general lubrication accounts for 70%-80% of the bearing space, too much or too little is not conducive to bearing lubrication and heat transfer. The bearing extends its service life.
(3) The bearing cover is too tight with the shaft, and the bearing is too tight or too loose with the shaft, which will cause the bearing to overheat. Once this problem occurs, there will be a grinding sound and obvious swing in the operation of the equipment. The universal crusher should be stopped and the bearing removed. Trim the friction area and reassemble as required.
Universal dust removal grinder plugging analysis:
Blockage is one of the common faults in the use of the mill, and there may be problems in the design of the machine, but more is caused by improper operation.
(1) The feed speed is too fast, the load increases, and the blockage is caused. In the feeding process, we should always pay attention to the ammeter pointer deflection Angle is large, if the rated current is exceeded, it indicates that the motor is overloaded, long-term overload will burn the motor. In this case, the feed door should be reduced or closed immediately, and the feeding method can also be changed to control the feed amount by increasing the feeder. There are two kinds of feeders, manual and automatic, and users should choose the right feeder according to the actual situation. Due to the high speed of the universal grinder, the load is large, and the load volatility is strong. Therefore, the current of the mill is generally controlled at about 85% of the rated current.
(2) The discharge pipe is not smooth or blocked the feed is too fast, which will make the universal crusher tuyere clogged; Improper matching with the conveying equipment will cause the wind of the discharge pipeline to weaken or block after no wind. After finding out the fault, it should first clear the delivery port to change the mismatched conveying equipment, adjust the feed amount, so that the equipment can operate normally.
(3) Hammer fragment, aging, screen hole closure, tattered, crushed material water content is too high will make the universal dust removal crusher blocked. The broken and seriously aging hammer should be regularly updated to maintain the good working condition of the crusher, and regularly check the screen, the water content of the crushed material should be less than 14%, which can improve the production efficiency, but also make the universal dust removal mill is not blocked, and enhance the reliability of the work of the crusher.
