The principle of disc wood chipper and drum wood chipper is similar,the cutting blades combine with the fixed knives or machine body to realize wood cutting.To control the thickness and size of finished products,it is very important to control the cutting blades’ angle and length and distance between fixed knives.

    
1.The length of cutting blade extension determines the thickness of finished wood chips.
The thickness of finished wood chips can be adjusted by controlling the length of blade extension.
2.The angle of cutting blade of wood chippers and a great relationship with finished wood chips’size.
But in general,it is adjusted by manufacture,can not be changed.And it is not recommended to change the blade angle yourself.
3.The distance between the cutting blade and fixed knife of wood chipper machine,if this distance is not well controlled,it will appear the collision or occlusion between the cutting blade and fixed knife in the process of working,which is very dangerous for the production,will cause fatal impact on the wood chipper itself,but also pose a threat to the operator.So manual rotation and debugging are needed after adjustment.
4.The width of wood chips is formed by natural rupture,which depends on the transverse shear strength of raw material,generally slightly less than the length of wood chips.
5.Whether drum wood chipper or disc wood chipper,all blades are required to have same extension length and accurately maintain the distance between the cutting blade and fixed knife.
