Abstract
A material comminution device has a housing. Cutters extend within the housing and move toward each other in a scissor-like manner. The cutters extend parallel to each other along a bottom portion and diverge along a top portion, and consist of comb-like rows of spaced blades that mesh with each other. The blades carry out at the same time a shearing movement and a swivelling movement around an axis by means of a crank mechanism.
Claims20
A device to comminute materials comprising:
- a housing;
- and
- a first cutter and a second cutter extending within the housing, the first and second cutters diverging from one another toward a top of the housing;
- wherein each of the first and second cutters include rows of spaced knives, knives of the first cutter being engaged with the knives of the second cutter;
- and
- wherein the first and second cutters are driven to simultaneously carry out a swiveling movement about an axis and a scissor-like movement.

A device to comminute materials comprising:
- a housing;
- a first cutter and a second cutter extending within the housing, the first and second cutters diverging from one another toward a top of the housing;
- and
- lower swivel arms;
- wherein each of the first and second cutters include rows of spaced knives, knives of the first cutter being engaged with the knives of the second cutter;
- and
- wherein the first and second cutters are driven to simultaneously carry out a swiveling movement about an axis and a scissor-like movement, and a plurality of the knives lie against the lower swivel arms.
4 more elements
A device to comminute materials comprising:
- a housing having a housing cover;
- a motor having a motor cover;
- and
- a first cutter and a second cutter extending within the housing, the first and second cutters diverging from one another toward a top of the housing;
- wherein each of the first and second cutters include rows of spaced knives, knives of the first cutter being engaged with the knives of the second cutter;
- wherein the first and second cutters are driven to simultaneously carry out a swiveling movement about an axis and a scissor-like movement;
- and
- wherein opening the housing cover moves the first cutter and the motor cover backward.
5 more elements
A method of comminuting materials comprising:
- providing a housing;
- providing first and second cutters having rows of knives extending within the housing, the first and second cutters diverging from one another toward a top of the housing;
- driving the first and second cutters to simultaneously carry out a swiveling movement about an axis and a scissor-like movement.
