To maximize your pellet machine, there are three keys: daily inspection, routine maintenance, and material testing.
When you know your device well, you know when something went wrong. Detecting problems early is crucial to preventing bigger problems.
1. Daily inspection
Daily inspections can let you know about your pellet machine and solve any problems immediately. Each shift walks around the pellet machine to check the oil level, temperature and meter. Listen to anything unusual and look for anything unusual. Whenever you start the pellet machine, be sure to check the die of the wood pellet machine. Check for foreign objects inside the mold; look for metal embedded in the impact crater or hole. It requires less labor, snatching unstable metals when they first appear, rather than waiting until it is embedded in deeper holes. Don't forget to identify and correct the source of unstable metals.
Do you see uneven wear on the mold surface? Adjust the deflector into the appropriate recommended gap. The longer you allow uneven wear to last, the shorter the wear life of the mold and rolls, because you will eventually be unable to adjust the rolls correctly. Material changes can sometimes cause the need to change the mold specifications to resolve uneven wear. Also remember that every old retired mold is a historical lesson and be sure to check them out.
2. Routine maintenance
In our industrial environment, routine maintenance is necessary. Adjusting scrolling is one of the common things. Granular machine manufacturers recommend skip adjustments to molds by rollers, where the rollers almost skip the mold because it is rotating to maximize mold life. While tightening the roller to the mold may not be too easy to clog, it does accelerate wear and fatigue of the mold. The surface of the roll is harder than the mold, so the metal-to-metal contact will quickly wear the mold and cause the mold to roll over. Mold flip refers to the hole being partially blocked by metal, which reduces production capacity and leads to clogging. A sufficiently large pressure will cause the mold to fail completely. A strong preventive maintenance program will result in a minimum total cost of ownership.
3. Material testing
Regular testing of materials before and after granulation is key to optimizing processes and equipment. Check the moisture into the wood pellet machine, when making wood chip pellet it should usually be 10%, you want to keep it consistent and be within a narrow range as much as possible. The feed size must be appropriate to meet capacity and quality objectives. When hammers and screen wear appear on your hammer mill, they will produce larger products, which will negatively affect the performance of the pellet machine.
Check the particle temperature, PDI (particle durability index), and moisture leaving the cooler regularly. The sooner these differences are discovered, the sooner they can be resolved. Typically, a reduction in capacity or PDI will be the first signal to replace the mold. A new mold can quickly compensate for its lost capabilities.
