Abstract
The present invention provides a double-functional rolling blade wheel group having two rolling blade wheels. Each of the rolling blade wheels includes a number of rolling blades arranged in a longitudinal direction thereof. The rolling blades of one rolling blade wheel cooperate with the rolling blades on the other rolling blade wheel, so as to shred objects. Each of the rolling blade wheels forms at least two shredding areas along the longitudinal direction thereof. The number of blade rows along a circumference direction of one shredding area and the number of the rolling blades in each blade row along the longitudinal direction of the shredding area are different from those formed on the other shredding area.
