Abstract
The mechanical crusher includes a rotating shaft, a rotor mounted about the rotating shaft and having at least one sub-rotor containing a plurality of blades, a liner having a plurality of grooves formed on the inner peripheral surface thereof and disposed externally of the rotor with a predetermined gap defined between the inner peripheral surface thereof and the outer-peripheral surface of the rotor, and a drive unit for rotating the rotor. The blades of at least the one sub-rotor incline in a direction where the flow of a material to be crushed is forced back. With this arrangement, the mechanical crusher can effectively crush a fiber-incluing material such as wheat bran, and the like to fine powder.

A mechanical crusher comprising:
- a rotating shaft;
- a rotor mounted about said rotating shaft and having at least one sub-rotor containing a plurality of blades;
- a liner having a plurality of grooves formed on an inner peripheral surface thereof and disposed externally of said rotor with a predetermined gap defined between the inner peripheral surface thereof and an outer peripheral surface of said rotor;
- and
- a drive unit for rotating said rotor and coupled to said rotating shaft,
- wherein each of said plurality of blades of said at least one sub-rotor inclines with respect to an axial direction of said rotating shaft such that a flow of a material to be crushed is forced back.
A mechanical crusher for a fibrous material comprising:
- a rotating shaft;
- a rotor mounted about said rotating shaft and having at least one sub-rotor containing a plurality of blades;
- a liner having a plurality of grooves formed on an inner peripheral surface thereof and disposed externally of said rotor with a predetermined gap defined between the inner peripheral surface thereof and an outer peripheral surface of said rotor;
- and
- a drive unit for rotating said rotor and coupled to said rotating shaft, wherein a pitch of said plurality of blades of at least one sub-rotor of said rotor on said outer peripheral surface of said rotor in a rotational direction of said rotor is set to 8 mm to 40 mm.
