Solving common problems in the production process of slag ultra-fine vertical mill

Author:clirik     Time:2021-04-12 09:35
After the slag ultra-fine vertical mill is produced for a period of time, some users will encounter various equipment failure problems. The following summarizes the problems and solutions in the production process of the slag ultra-fine vertical mill.
 
The most direct problems for users in the production process of ultra-fine slag vertical mills are mainly equipment noise or vibration, no powder output or reduced output, and the powder becomes coarse or fine.

ultra fine vertical mill

The main noise or vibration of the slag ultra-fine vertical mill is too loud. The possible causes and solutions are as follows: the grinding roller does not rotate, which requires disassembly and washing of the grinding roller device; the grinding ring is loose and the grinding ring needs to be tightened; falling into the metal Objects, check whether there are any metal objects inside the machine body falling into it, and remove it; uneven feeding and less feeding, need to adjust the feeding amount; the two halves of the coupling have different shafts, and the coaxiality of the coupling needs to be calibrated; The roller is worn out, deformed out of round, and the grinding roller needs to be inspected and replaced in time; the foundation is not strong, and the foundation needs to be reinforced.
 
The powder is too coarse or too fine during the grinding process. On the one hand, the speed of the classifier does not match the required grading particle size of the material, and the speed of the classifier must be adjusted; on the other hand, the air volume of the blower is not appropriate, if the powder is too coarse , When adjusting the speed of the classifier can not reach it, you can properly close the valve of the air inlet pipe of the blower. If the powder is too fine, you can reduce the speed of the classifier or remove the classifier to increase the speed of the blower.
 
The slag ultra-fine vertical mill has no or less powder output due to the following reasons: the discharge valve (air lock) is not tightly closed, the outside air and dust are sucked backwards, and the discharge valve needs to be repaired; main engine wind If the channel is blocked, the blockage should be removed; the blade is worn, resulting in too little or unable to shovel material, so check the wear of the blade and replace the blade; the pipe and flange joints are seriously leaking, and the leak should be carefully checked. Reseal the air.
 
In addition, various other problems will occur after the long-term operation of the slag ultra-fine vertical mill, some of which are even difficult problems, which require very experienced professionals to solve.
 
No mechanical equipment can guarantee that there will be no failure during operation. CLIRIK reminds the majority of users of ultra-fine slag vertical mills that when choosing sufficient equipment, in addition to comparing the quality of the product itself, it is also necessary to comprehensively check whether the company’s after-sales service is complete. In-depth investigation to ensure that the equipment can continue to operate smoothly for a long time after installation.
