PROBLEM TO BE SOLVED: To provide a biaxial roll crusher which can easily crush a matter to be crushed, which has thicker thickness even though a roll size and a roll gap are equal to that of conventional one. SOLUTION: The roll crusher is provided with a first roll 1 and a second roll 2 which respectively have crushing teeth 7A, 7B on outer peripheral surfaces of roll main bodies 1A, 2A in a peripheral direction. The first roll 1 and the second roll 2 are respectively supported with freely rotating and are arranged in parallel to each other and are rotated in mutually opposite directions toward a gap S between roll main bodies 1A, 2A to crush the matter to be crushed charged on the rolls 1, 2. The 1st roll 1 and the 2nd roll 2 are provided so that highest height in a vertical direction of a top end part locus of the crushing tool 7A of each roll has height difference. Preferably the 1st roll and the 2nd roll are provided so that an angleθmade by a horizontal line and a line passing through shaft centers of respective rolls is 5°to 25°. COPYRIGHT: (C)2006,JPO&NCIPI
