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 Tips for Granulators**
Granulators are essential machines used in various industries, especially in processing wood, plastic, and other materials into smaller particles. However, like any mechanical equipment, they require regular maintenance and proper operation to ensure longevity and efficiency.
One of the most critical aspects of granulator maintenance is the **adjustment of the gap between the ring die and the press roll**. This adjustment must be done carefully to prevent excessive wear or operational issues. When setting up a new ring die and press roll, the two should just barely touch at their highest points. The goal is to achieve a "turning but not rotating" state, which ensures smooth operation without causing unnecessary strain.
If adjustments are made while the machine is running, it's important to increase the pressure slightly, but not so much that the clearance becomes too large. If the gap is too wide, the press roll may not rotate properly, leading to clogging and inefficiency. On the other hand, if the gap is too small, it can accelerate wear on both the ring die and the press roll, increasing the load and potentially damaging the components.
It’s recommended to **inspect the gap between the ring die and the press roll at least every four hours** during operation. Additionally, when adjusting the pressure rolls, make sure to align them correctly with the granulator’s shaft to avoid uneven forces that could affect performance.
Another key step is **pre-shift inspections**. Before starting each shift, operators should check the transmission parts, instruments, and valves. Lubrication is also crucial—use lithium-based lubricants to keep moving parts functioning smoothly and reduce friction. Removing any metal shavings or debris from the system is equally important to prevent contamination and damage.
When installing or replacing the ring die and press roll, always pair new dies with new rollers and old ones with old ones. This helps maintain consistent contact and ensures even distribution of force across the machine. Proper alignment and matching of these components contribute significantly to the granulator’s overall efficiency and output quality.
By following these guidelines, you can significantly extend the lifespan of your granulator and ensure optimal performance. Regular maintenance, careful adjustments, and attention to detail are all essential for keeping this vital piece of machinery in top condition.Guide Ring is a mechanical seal, also known as a guide ring. It is usually made of metal or plastic and used to support and position pistons or rods. Guide Ring has excellent wear resistance and corrosion resistance, which can effectively reduce leakage and friction, thereby extending equipment life. Guide Ring is widely used in the hydraulic, pneumatic, mechanical, and automotive industries as an important mechanical seal.
The classification of Guide Ring can be divided by material, structure, and purpose. According to material classification, Guide Rings are mainly divided into metal Guide Rings and plastic Guide Rings. Metal Guide Rings are usually made of metals such as copper, iron, and stainless steel, which have high strength, wear resistance, and high-temperature resistance; The plastic Guide Ring is usually made of polytetrafluoroethylene (PTFE), nylon, polyimide and other materials, with good corrosion resistance and low friction coefficient.
According to structural classification, Guide Rings are mainly divided into unidirectional Guide Rings and bidirectional Guide Rings. A unidirectional guide ring can only withstand pressure in one direction and is typically used in hydraulic and pneumatic systems; The bidirectional guide ring can withstand bidirectional pressure and is typically used in the mechanical and automotive industries.
According to usage classification, Guide Rings are mainly divided into piston Guide Rings and rod Guide Rings. The piston guide ring is usually used to support and position the piston, preventing friction and leakage between the piston and the cylinder liner; The rod guide ring is used to support and position the rod, preventing friction and leakage between the rod and the seal.
