Maintenance methods of small granulators

The pellet machine is an important application of modern industrial products. It is mainly used to process various wood fiber raw materials, such as sawdust, wood powder, rice husks, etc. The main feature is that the screen is easy to install and disassemble, and the tightness can be adjusted appropriately. It is easy to disassemble and clean. The following is an introduction to the maintenance methods of small granulators.

1. Overall environment related
Ventilation and heat dissipation: Place the small granulator in a well-ventilated position, which will help the motor to dissipate heat and avoid overheating of the motor, which will affect the performance and service life of the machine. Because the motor generates heat when working, if the heat cannot be dissipated in time, it may cause damage to the internal components of the motor, thereby affecting the normal operation of the entire granulator. For example, long-term overheating may cause damage to the insulation layer of the motor and increase the risk of short circuit.

2. Mechanical parts related
Lubrication and maintenance
Regularly check and replace the reducer gear oil, and keep the oil level in the center line of the oil window. This is because the reducer plays an important role in the working process of the granulator. If the gear oil is insufficient or the oil quality deteriorates, it will increase the friction between the gears, resulting in increased wear and affecting the service life and work efficiency of the reducer.

Regularly add lubricating oil to moving parts such as bearings. For example, you can use a grease gun to operate according to the specified filling points and frequency. Bearings need good lubrication during operation, otherwise they are prone to wear, jamming and other problems, affecting the smooth operation of the machine. The bearings of automatic feeders, vertical spin dryers, pelletizer holders and other components in small granulators need to be lubricated and maintained.

Tool maintenance
Frequently check the fastening of the tool. For example, after a new granulator has been used for 1 hour, it is necessary to use tools to tighten the screws of the moving knife and the fixed knife to strengthen the fixation between the blade and the knife holder. Because during the operation of the granulator, the tool may become loose due to vibration and other reasons. If it is not tightened in time, it may affect the granulation effect, and even cause tool damage or other safety hazards.

Check the sharpness of the tool and handle it in time to ensure its sharpness. Blunt tooling will affect the granulation effect, and may also increase the load of the machine and cause unnecessary damage to other parts. When replacing the tool, pay attention to the gap between the moving knife and the fixed knife. For example, if the recycled material is thinner than 20HP, the gap can be appropriately increased.

Cleaning and maintenance
Regularly clean the debris and dust inside and outside the machine room to keep the machine clean. If the debris and dust accumulate too much, they may enter the running parts of the machine, such as bearings, increase the risk of wear, and may also affect the performance of electrical components, leading to increased hidden dangers of failure.

Check and clean the discharge port to prevent blockage from affecting production. If the discharge port is blocked, the material cannot be discharged normally, causing the internal pressure of the machine to increase, which may damage the internal components of the machine and affect production efficiency.

3. Electrical safety related
Ensuring that the small granulator is well grounded is an important measure to prevent safety accidents caused by electrical failures. If the grounding is not good, once electrical leakage occurs, the operator may be electrocuted, causing serious personal injury.

Regularly check the integrity of wires and cables, and replace them in time if they are damaged. Damage to wires and cables may cause short circuits, leakage and other problems, affecting the normal operation of the granulator and posing safety risks.

4. Regular inspection related
Machine inspection: Once a month, check whether the worm gear, worm, bolts on the lubrication block, bearings and other active parts are flexible and wear-resistant. If defects are found, they should be repaired in time and should not be used reluctantly. If the problematic parts are used reluctantly, the problem may be further aggravated, affecting the normal operation of the entire granulator, or even causing serious damage to the machine.

Inspection after shutdown: After the machine is used or stopped, the rotating drum (if any) should be removed for cleaning and the remaining powder in the bucket (if there is a bucket structure) should be brushed out, and then installed properly to prepare for the next use. This can prevent the residual material from corroding the machine or affecting the product quality when it is used next time. In addition, when the machine is shut down for a long time, all power supplies should be turned off and the materials in the equipment should be emptied to avoid accumulation and corrosion inside the equipment.
