What is the distance between the bottom knife of the wood chipper? Let's expand on it.

In the process of using the wood chipper, the distance between the bottom knife and the flying knife is a very important parameter, which directly affects the quality and output of the chips. The following is the relevant information about the distance between the bottom knife of the wood chipper based on the search results.

According to the search results, the distance between the flying knife and the bottom knife of the wood chipper should be kept between 0.8 and 1.5 mm. The setting of this distance is crucial to ensure the cutting quality and reduce energy consumption. If the distance between the flying knife and the bottom knife is not appropriate, it may lead to a decrease in cutting quality and even affect the normal operation of the equipment.

Distance adjustment between the bottom knife and the flying knife

In actual operation, the distance between the bottom knife and the flying knife of the wood chipper needs to be maintained by regular adjustment. Generally speaking, the flying knife of the wood chipper should be replaced and ground every 4 to 8 hours, and the bottom knife should be replaced every half a month. In this process, the distance between the flying knife and the bottom knife can be changed by adjusting the position or angle of the flying knife and the bottom knife. When adjusting, make sure that all blades extend the same amount and keep the distance between the fly knife and the bottom knife well.

In addition to the distance between the fly knife and the bottom knife, there are several other factors that affect the quality of the chips:

The quality of the raw materials: The quality of the raw materials themselves directly affects the quality of the wood chips, so the raw materials are required to be good and regular in shape, have a certain moisture content, no decay and less skin.

Choice of wood chipper knives: The sharpness of the wood chipper knives directly affects the quality of the chips. The fly knife blades are single-edged and double-edged. To ensure the sharpness of the blade edge, the blades are required to be regularly ground and replaced.

Installation of blades: The length and thickness of the wood chipper raw material chips are determined by the installation position and angle of the blades. The width of the chips is formed by natural rupture, which depends on the cross-grain shear strength of the raw materials1.

In summary, keeping the distance between the fly knife and the bottom knife of the wood chipper between 0.8~1.5mm is the key to ensure the quality of the chips. At the same time, it is also necessary to pay attention to the quality of the raw materials, the selection and installation position of the knives to obtain good chipping effects. During use, if the chipping quality is found to be poor, these factors should be checked and adjusted in time.
