After the Raymond mill is put into operation for a period of time, a series of overhaul and maintenance measures must be taken, such as overhaul of the internal parts of the Raymond mill, replacement of lubricating oil, dust removal, etc., so as to protect the Raymond mill, reduce the loss of its parts and prolong its service life. After consulting the after-sales technical engineer of electromechanical equipment, Xiaobian now arranges the overhaul methods and maintenance methods of Raymond pulverizer as follows, hoping to help customers.

Raymond mill equipment maintenance has the following methods:

(1) Forced repair method this method is to make a specific plan in advance for the repair date, category and content of the pulverizer equipment, and carry out it in strict accordance with the plan, regardless of the actual technical status of the pulverizer equipment. The utility model has the advantages that it is convenient to make full preparations before repair, and can most effectively ensure the normal operation of the pulverizer equipment. This method is applicable to particularly important and complex pulverizer equipment that must strictly ensure safe operation, such as vertical pulverizer, ultra-fine pulverizer, Raymond pulverizer, pulverizer equipment on centrifugal pulverizer, etc.

(2) The regular repair method is to formulate the planned date and schedule for the repair of the pulverizer equipment according to the actual use of the pulverizer equipment and referring to the relevant maintenance cycle

Repair workload caused by. This method is conducive to making preparations before repair.

(3) Repair after inspection method this method specifies the inspection plan of pulverizer equipment in advance, and determines the repair date and content according to the inspection results and previous repair data. This method is simple and easy, but if it is not mastered well, it will affect the preparation before repair.

(4) The partial repair method is characterized in that all parts of the pulverizer equipment are not repaired at the same time, but are repaired according to the independent parts of the pulverizer equipment and in sequence, and only one part is repaired each time. The advantage of this method is that because the repair workload is scattered and divided into parts, it can be repaired in holidays or non production time, which can increase the production time of pulverizer equipment and improve the utilization rate of pulverizer equipment.

(5) The component repair method removes the parts of the pulverizer equipment to be repaired and replaces them with the same parts prepared in advance, that is, replace the parts with a simple "insert" and "pull-out" method. The advantage of this method is that it can save disassembly time, but its disadvantage is that it requires a certain number of spare parts and takes up a lot of money.

(6) Synchronous repair method refers to that several pulverizer equipment closely related to each other in the process of production are arranged to be repaired at the same time to realize the synchronization of repair, so as to reduce the downtime occupied by decentralized repair.

For the above methods, different repair methods can be adopted for different pulverizer equipment in the same grinding station. The latter three are more advanced organization methods.

Maintenance method of Raymond Mill:

1. Raymond pulverizer should be supervised by fixed personnel during use, and the operators must have a certain technical level. Before the installation of the pulverizer, the operators must be provided with necessary technical training to make them understand

2. In order to ensure the normal operation of Raymond mill, the "equipment maintenance and safe operation system" of the equipment shall be formulated to ensure the long-term safe operation of the mill. At the same time, necessary maintenance tools, grease and corresponding accessories shall be provided.

3. After Raymond pulverizer is used for a period of time, it shall be overhauled, and vulnerable parts such as grinding roller, grinding ring and blade shall be overhauled and replaced. The connecting bolts and nuts of the grinding roller device shall be carefully checked before and after use to see whether there is looseness and whether the lubricating grease is sufficient.

4. When the roller grinding device is used for more than 500 hours to replace the roller, the rolling bearings in the roller sleeve must be cleaned, and the damaged parts should be replaced in time. The refueling tools can be manual refueling pump and grease gun.
