Everyone knows that the granulator often suffers from various wear and tear during the process of use . Sometimes it may cause some minor faults due to improper operation . Therefore, in order to effectively extend the service life of the equipment , we must work in the usual work. To operate in the right way :
　　 1. Adjustment of the gap between the ring die and the press roll For the adjustment of the gap between the new ring die and the press roll , the ring die and the highest point of the press roll should be slightly contacted , and the press roll can reach the state of " like turning and non-turning " . If yes be adjusted in the operating state, may be appropriate to increase the pressure of the pressure roller and the ring mold, but it must be enough is enough clearance ring mold and the pressure roller is excessively large, the pressure roller can not be rotated, causing plugging machine gap of the ring die and the press roll If it is too small , it will increase the wear of the ring die and the pressure roller, and the load will increase , which will seriously damage the ring die and the pressure roller . Check the gap between the ring die and the pressure roller in time, and check it at least every four working hours . when adjusting the respective pressure roller, to adjust the direction of each platen roller, should the pressure roller relative to the respective zero torque and granulator shaft so that the wood granulator asymmetric forces from impact.
　　 2 , the team maintenance granulator should do pre-work inspection every shift , check the transmission parts, instruments, valves , add lubricated oil using lithium-based lubricants , and remove iron filings on the iron .
　　 3 , the correct installation or replacement of the ring mold and the pressure roller is generally a new mold with a new roller , the old mold with the old roller , so that the surface shape of the ring mold and pressure roller is close to the contour state , the gap between the ring mold and the pressure roller The same is the same . This way the entire ring mold is very uniform in force and discharge , which can improve production efficiency .

**Proper Operation and Maintenance of Granulators**
Granulators are essential machines in many industrial applications, especially in the processing of materials like wood, plastic, and other organic substances. However, these machines are prone to wear and tear over time, which can lead to inefficiencies and even breakdowns if not properly managed. Understanding how to operate and maintain a granulator correctly is crucial for maximizing its lifespan and ensuring smooth operations.
One of the most important aspects of granulator maintenance is the proper adjustment of the gap between the ring die and the press roll. When first installed, the ring die and the top of the press roll should just barely touch. This creates a condition where the roll appears to turn but isn’t fully rotating — a state often referred to as “turning without turning.†Adjusting this gap while the machine is running should be done carefully. Increasing the pressure of the press roll and the ring die might be necessary, but it’s important not to overdo it. If the clearance is too large, the roll may not rotate at all, leading to blockages. On the other hand, if the gap is too small, it can cause excessive wear on both components and increase the load on the system, potentially damaging the machine.
To prevent such issues, it's recommended to check the gap between the ring die and the press roll at least every four hours of operation. Additionally, when adjusting the pressure rolls, make sure they are aligned correctly with the corresponding plates and the granulator shaft. This helps avoid uneven forces that could cause unnecessary stress on the machine.
Another key practice is conducting a thorough pre-shift inspection. Before starting the machine, operators should check all moving parts, gauges, and valves to ensure everything is functioning properly. Lubrication is also vital — using high-quality lithium-based grease can reduce friction and prolong the life of the machine. It’s also important to clean any metal shavings or debris that may have accumulated, as these can interfere with the machine’s performance.
Finally, the installation or replacement of the ring die and press roll should always be done correctly. It’s best to pair a new ring die with a new press roll and an old one with another old one. This ensures that the surface contours match closely, maintaining consistent gaps and reducing uneven wear. Proper alignment and matching of these components help distribute the workload evenly across the machine, improving efficiency and reducing downtime.
By following these guidelines, operators can significantly extend the life of their granulator and ensure it runs smoothly and efficiently. Regular maintenance, careful adjustments, and attention to detail are the keys to successful granulator operation.Buffer ring is a common Machine element, which is used to reduce the vibration and noise generated during the operation of the machine. Buffer rings are mainly divided into two types: rubber buffer rings and spring buffer rings. Rubber buffer rings are suitable for low-frequency vibration and impact, while spring buffer rings are suitable for high-frequency vibration and impact. Buffer ring is an important Machine element, which is widely used in automobile, machinery, electronics and other fields.
