Common problems and solutions during the use of Raymond mill

Raymond Mill is the most widely used milling equipment. Many users in China use Raymond Mill. SBM Heavy Industry is a professional manufacturer of Raymond Mill. It has rich experience and independent innovation and upgrade equipment. There is very little sales on the market. For China's micro-small enterprises, Raymond mill has low initial equipment investment and simple operation, which is suitable for the small cost of small and medium-sized enterprises. SBM Heavy Industries Raymond Mill has significantly improved its production and product fineness and environmental performance.

After the Raymond mill is in production for some time, some users will encounter various equipment failure problems. Some users will buy second-hand equipment or some small informal factories. Many small-factory mobile phones do not have quality assurance and after-sales service. When the user does not have a professional technician, it will be difficult to solve the problem. If you go around and ask for help, the equipment will be shut down for a long time and cannot be produced. We often provide technical assistance to users. Let's analyze the common problems of ore mills and how to deal with them: The Raymond mill has direct problems for the user during the production process, mainly because the equipment noise or vibration is too large, no powder or yield is reduced, and the powder becomes coarse or thin.

Raymond mill main engine noise or vibration is too large, the possible causes and solutions have the following aspects: the grinding roller does not rotate, which requires the washing and rolling device; the grinding ring is loose, the grinding ring needs to be tightened; Check whether there are metal objects falling inside the body and remove them; the feeding is uneven and the feeding is small, the feeding amount needs to be adjusted; the two halves of the coupling are different axes, the coaxiality of the shaft joints needs to be corrected; the grinding roller wears If the deformation is out of round, it is necessary to check and replace the grinding roller in time; if the foundation is not strong, the foundation needs to be reinforced.

During the grinding process, the powder is too thick or too fine. On the one hand, the speed of the classifier does not match the graded particle size required for the material, and the speed of the classifier should be adjusted. On the other hand, the air volume of the blower is not appropriate. When the speed of the classifier is not reached, the blower valve of the small blower can be properly closed. If the powder is too fine, the speed of the classifier can be reduced or the classifier can be removed to increase the blower speed.

Raymond mill does not produce powder or less powder, there are the following reasons: the discharge valve (locker) is not closed semi-closed, the outside air, dust sucking, to repair the discharge valve; host wind The road is blocked, the blockage is removed; the blade is worn, causing too little scrap or material to be shoveled, so check the blade wear and replace the blade; the pipe and flange joints are severely leaking, and you should check carefully to find the leak. The gas is resealed.
