Wood chipper is an important equipment in the forest products processing industry, widely used in processing wood into wood chips for paper production, biofuel, or raw materials for making biochar. However, during operation, wood chipper is very susceptible to overload problems. If not handled promptly, overload can lead to serious damage, reducing the life of the machine as well as increasing maintenance costs.

In this article, let’s learn with GREEN MECH about measures to protect wood chipper from overload, from basic principles to system maintenance and monitoring techniques.

Understanding the causes of wood chipper overload

Wood chipper machines, such as GREEN MECH, operate on the principle of cutting wood into chips through a system of high-speed rotating blades and chipping plates. When too much or too hard wood is fed in, the chipping blades and chipping plates cannot process all the material in time, causing jams or delays in the chipping process. Common causes of overload include:

• Wood chipper can only process wood efficiently within a specific size limit. When the input wood is too large or too thick, the chipper blade and chipping plate system cannot handle it in time, leading to machine overload.
• If the wood is harder than normal or contains impurities such as rocks or gravel, the chipper will have to work harder to cut through, causing jamming and slowing the chipping process. Wood types with uneven hardness can easily lead to uneven pressure, increasing the risk of damage.

• When the chopper blades are not sharpened regularly or the chopping plate is worn, the machine’s performance is severely reduced. This forces the machine to operate at a higher intensity, causing it to overload quickly.
• Errors in the control system, especially when the feed rate cannot be adjusted accurately, can cause the feed rate to be too fast or too much, resulting in the machine having to process a volume that exceeds its capacity.

Understanding the causes of overloading will not only help you adjust and operate your wood chipper more efficiently, but it will also help you optimize production performance. This means you can minimize breakdowns, save on maintenance costs, and extend the life of your equipment.

Design and select the appropriate chopper

Choosing the right wood chipper for your production needs not only helps optimize the process but also ensures long-term and stable performance. Each type of wood chipper has different specifications and operating capacity, so to ensure the equipment operates efficiently and avoid overloading, businesses need to consider carefully before making a decision.

When evaluating and selecting a wood chipper, it is important to clearly identify the specific production needs of the business. For large, hard wood or wood that needs to be processed in large volumes, choosing a high-capacity chipper is a prerequisite. GREEN MECH’s high-capacity wood chipper lines, such as the GM-15DC model, are capable of chipping 15 to 17 tons of wood per hour, making them ideal for businesses that need to chisel hardwood in large quantities.

Machines with large chipping plates, sharp blades and high durability will help increase efficiency, reduce the risk of overloading, and ensure consistent output quality of wood chips. This not only improves production efficiency but also helps save operating and maintenance costs in the long run.

In addition to capacity, when choosing a wood chipper, other technical factors also need special attention.

• For the wood chipper machine to be able to handle large types of wood, the blade diameter needs to be large enough to withstand strong cutting pressure. The GREEN MECH wood chipper is designed with a chipping plate made of SS400 steel – a type of steel with very high durability and load-bearing capacity, ensuring that the chipping plate does not wear out quickly during operation. SS400 steel is also able to withstand strong impacts, helping the chipping plate operate stably even when processing hard wood.
• Another key factor is the chopping blade. GREEN MECH machines use chopping blades machined on CNC machines, achieving high precision and good abrasion resistance. Sharp chopping blades help the chopping process go smoothly, avoiding jamming or damage due to overload.
• Many modern wood chipper machines are integrated with intelligent automatic control systems, which help adjust the amount of wood fed into the machine based on the hardness and size of the raw material. This not only ensures stable operation of the machine but also helps reduce pressure on the blade system and chipping plate, increasing the machine’s life and limiting overloading.

Choosing a wood chipper is not only based on capacity but also requires attention to technical factors and durability of each important part such as the chipping plate and the chipping blade. A quality wood chipper, such as the GREEN MECH series, with optimal design and advanced technology, will be a great assistant for businesses in improving production efficiency and protecting equipment from overload.

Adjust and control operating procedures

One of the important measures to avoid overloading is to adjust the feeding process. The GREEN MECH wood chipper is equipped with an intelligent control system, which can automatically adjust the amount of wood fed based on the hardness and size of the raw material. Operating this control system will help reduce the pressure on the knife and chipping plate.

In addition, conveyor speed control is also very important in the operation process. The feeding conveyor and the discharging conveyor need to be strictly controlled to avoid the raw material being compressed or being fed too quickly.

Regular maintenance

Regular maintenance is key to maintaining the performance and longevity of your wood chipper.

• Check and sharpen the chopping blade: The chopping blade is the most important and stressed part, it needs to be checked and sharpened periodically to ensure the blade is always in the best condition. A dull chopping blade will reduce cutting performance and increase the risk of overload.
• Check the electrical system and motor: The control electrical system and motor need to be checked and maintained periodically to avoid signal errors or motor overload due to continuous operation.

• Check the drive and belt: The drive system plays an important role in transferring power from the engine to the chopper. Parts such as belts and pulleys need to be checked and replaced when there are signs of wear.
• Cleaning the system: The wood chipping process will create a lot of sawdust and small wood chips, if not cleaned regularly, this dirt can accumulate in the gaps and cause the machine to jam.

Load monitoring and early warning

In modern wood chipper systems , load monitoring and early warning have become an indispensable factor, helping to ensure safe and efficient operation. GREEN MECH, with advanced technology, has integrated load sensors into its wood chipper lines, providing continuous, accurate monitoring and timely handling when there are signs of overload.

Load cell – Wood chipper protection shield

The load sensor is one of the breakthrough tools that continuously monitors the machine’s operating status. When the load exceeds the pre-set safety threshold, the system will immediately send a warning and automatically take protective measures such as reducing speed or stopping the machine. This helps prevent overloading, protecting important components such as the chopper blade, chopping plate, and drive system from serious damage.

In addition, GREEN MECH’s warning system is also equipped with sound and light indicators, making it easy for operators to detect problems remotely. This is especially useful in large factories where direct monitoring of each device can be difficult. Thanks to this warning system, overload errors can be detected early and handled promptly, avoiding interruptions to the production process and saving maintenance costs.

Automatic load adjustment system

Another advanced feature of the GREEN MECH wood chipper is its ability to automatically adjust the load when it detects signs of overload. Instead of waiting for a problem to occur, the system will rely on data from the sensor to adjust the speed and amount of wood being fed, ensuring the machine always operates within safe limits. This helps to minimize wear on components and prolong the life of the machine.

Operator Training – Improve Efficiency and Safety

One important aspect that cannot be overlooked in protecting wood chipper from overloading is operator training. No matter how modern and intelligent the machine is, if the operator lacks the necessary skills and knowledge, the risk of an accident is very high.

GREEN MECH not only provides quality wood chipper machines, but also provides in-depth training support services for operators. The training program includes knowledge about:

• Understand the machine’s capacity and specifications: This helps employees know how to use the machine within safe limits, not allowing the machine to handle volumes or types of wood that exceed its design capacity.
• Efficient operation skills: Instructions on how to feed properly to avoid overloading or overfeeding, which helps to minimize the risk of overloading and damaging the chopper.
• Detect and handle problems promptly: Staff will be trained to recognize signs of overload through the warning system, as well as the steps to take to fix it immediately.

This training not only helps improve operating efficiency but also significantly reduces maintenance and repair costs, while helping to protect the wood chipper to operate durably and efficiently for a long time.
