During the long-term use of wood crusher, the blade will inevitably becomes dull, which will affect the normal operation of the equipment. This paper will analyze the reasons why the blade of wood crusher becomes dull, and put forward corresponding solutions.

First, insufficient lubrication

Lubrication is an important link to ensure the normal operation of mechanical equipment, and the blade of wood crusher is no exception. If the lubrication is not in place or the quality of lubricating oil is poor, the friction between the blade and other parts will be aggravated, thus accelerating the wear of the blade. In this case, the blade may become dull or even be damaged in a short time.

Solution: Check the lubricating system regularly to ensure the sufficient amount of lubricating oil; Use high-quality lubricating oil suitable for equipment.

Second, the blade is slightly worn

In daily use, it is inevitable that the blade will be slightly worn due to cutting hard wood or contact with sundries. Although this situation will not immediately affect the performance of the equipment, if it is not handled in time, the wear will gradually increase, eventually leading to the loss of sharpness of the blade.

Solution: Check the wear of the blade regularly, and polish or repair it in time if it is found to be slightly worn; Avoid letting the blade treat wood that is too hard or contains more impurities for a long time to slow down the wear speed; Standardize the use of machines.

Third, the blade is seriously worn

If the slight wear of the blade is not treated in time, or it is used in harsh conditions for a long time, it may lead to serious wear of the blade. This will not only affect the cutting efficiency of wood crusher, but also cause collateral damage to other parts of the equipment.

Solution: When the blade is seriously worn, stop using it immediately and replace it with a new blade; Strengthen daily maintenance to avoid excessive blade wear due to negligence.

Fourth, not cleaned in time

Wood crusher will produce a lot of sawdust, resin and other residues in the process of work. If these substances are not cleaned in time, they will adhere to the surface of the blade and affect its sharpness. In addition, these residues may also accelerate the corrosion and wear of the blade.

Solution: After using the equipment every time, clean the blade surface and surrounding parts in time to remove residues such as sawdust and resin; Thoroughly clean the equipment regularly to ensure that all components are in good condition; In the cleaning process, the blade can be treated with special cleaning agent to prolong its service life.

The causes of dullness of the blade of wood crusher machine are mainly concentrated in four aspects: insufficient lubrication, slight wear, serious wear and failure to clean in time. In order to prolong the service life of the blade and improve the working efficiency of the equipment, it is necessary to start with daily maintenance and make regular inspection, timely repair and cleaning. At the same time, in the process of operation, the operation is strictly in accordance with the equipment use specifications, which can also effectively reduce the possibility of the blade becoming dull. Only by doing these basic tasks well can we ensure that wood crusher will always operate efficiently and create more value for enterprises.
