How to replace worn rollers and bearings in a roller mill grinder

roller mill grinder is a common and important equipment in industrial production. Due to long-term use, the rollers and bearings will wear out, affecting the performance of the equipment. So as roller mill grinder owners, we must promptly replace the worn rollers and bearings in the roller mill grinder to ensure smooth operation and efficient performance of the equipment.

First of all, we must check the wear and tear in time


In normal use, within a fixed period of time, we must promptly check the wear of the rollers and bearings to determine which parts need to be replaced. Signs of wear that need to be checked regularly include the following.

Drum wear: The drum surface may have dents, cracks, or uneven wear, which may result in reduced grinding efficiency.
Worn Bearings: Bearings often make noise and feel uneven when spinning, which is a sign of worn bearings.
Lubrication issues: Check the lubrication of the rollers and bearings. Dry lubrication or insufficient lubrication may cause wear.

Preparing for replacement of worn parts


Once we find that the wear level needs to be replaced during the inspection process, we must start preparing for replacement. First of all, before replacing the rollers and bearings, you must first cut off the power and disconnect the air source: ensure that the equipment is powered off to prevent any accidents. Secondly, you need to prepare the materials and tools required for the replacement process: such as the required new rollers, bearings, grease, and appropriate tools such as wrenches, screwdrivers, etc.

Replacement of worn rollers of roller mill grinder


First, unload the old rollers of the roller mill grinder: Unload the worn rollers according to the structure of the equipment. Typically, this involves removing adjacent components such as belts, chains, or other connections. During this process, be sure to pay attention to the disassembly of this component and do not use brute force. Next comes the installation of the new drum: Install the new drum into the machine correctly and make sure it is aligned with the axis. Tighten the rollers according to the equipment model and manufacturer's guidelines. Finally, add new lubrication. Make sure the new roller is well lubricated to reduce friction and wear.

First, the worn old bearings of the roller mill grinder are unloaded. Use appropriate tools and methods to remove worn bearings from equipment. This may require some strength and skill. Then, take out the prepared new bearing and implant the new bearing into the equipment. Make sure they are installed correctly and strictly follow the manufacturer's guidelines. Finally, lubricant still needs to be added, and the bearings should be properly lubricated to ensure smooth operation.
 

Testing and calibration of roller mill grinder parts after replacement

Once the roller mill grinder's drums and bearings have been replaced, testing and calibration must be performed to ensure proper operation of the equipment. This includes reconnecting power and air to the equipment and making sure everything is working properly. It also includes running tests, booting up the device and watching it run. Check the new rollers and bearings for noise-free operation and smooth operation. Finally there are adjustments and calibrations, which are performed as needed to ensure the device is performing at its best.

These tasks are indeed more complex. Professional matters also require professional guidance and operation.
