A mineral material crusher (30, 200; 500, 510) comprising: a body (11, 211; 511); a rotating crusher element (13, 215; 513);a drive shaft arrangement (212,215) configured to support the rotating crusher element to the body and to rotate the rotating crusher element; and a motor comprising a rotor (218; 516) for driving the drive shaft arrangement; the motor is formed inside the rotating crusher element; the drive shaft arrangement being configured to form for the rotor a rotating axle that is rigidly coupled with the rotating crusher element and capable of leading torque from the rotor to the rotating crusher element for rotating the crusher element around the drive shaft. A method comprising: supporting and rotating by a drive shaft arrangement (212,215) a rotating crusher element (13, 215; 513) of a mineral material crusher (30, 200; 500, 510) by a motor comprising a rotor (218; 16) for driving the drive shaft arrangement; forming the motor inside the rotating crusher element; forming by the drive shaft arrangement for the rotor a rotating axle that is rigidly coupled with the rotating crusher element and capable of leading torque from the rotor to the rotating crusher element for rotating the crusher element around the drive shaft. |
