Sizing technologies normally are devided into chipping or grinding technologies: | Sizing technologies normally are devided into chipping or grinding technologies: | ||
* chipping | * chipping | ||
: For chipping normally a chipper is used that consists of a sharp knife, that slice bigger parts into smaller chips. This is used e.g. for wood materials, straws and other feedstocks that can be cutted by a knife | |||
* grinding | * grinding | ||
: For chipping normally a grinder is used that cracks bigger parts into smaller particles. Grinding is achieved by shearing and/or friction and the grinding effect is achieved by multiple comminution in an increasingly narrowing grinding gap, which can usually be varied by axial displacement of a rotor or stator. | |||
