PURPOSE:To achieve miniaturization by reducing the number of parts and the number of kinds and to enhance the grinding efficiency of matter to be ground by providing fixed blades having the same width as rotary blades in a machine frame in opposed relation to the central part between the shafts of the rotary blades fixed to both rotary shafts at a predetermined interval. CONSTITUTION:A motor is provided to the right end of a drive shaft 6b to be rotated in the direction shown by a arrow A' and a drive shaft 6a is rotated in the direction shown by an arrow A through a gear. A plurality of rotary blades 2a, 2b are integrally fixed to the drive shafts 6a, 6b at predetermined intervals and rotated in the directions shown by the arrows A, A' so as to involve the matter to be ground. Fixed blades 3a and fixed blades 3b are provided to a machine frame 1 so as to be respectively opposed to the rotary blades 2b, 2a and the drive shafts 6a, 6b are loosely fitted in the through-holes 12 provided to the central part of the fixed blades 3a, 3b. The fixed blades 3a, 3b are constituted of the blade guide parts 13 fixed to the machine frame 1 and cutters 14 formed from a hard material and the cutters 14 are fixed to the upper surfaces of the guide parts 13 by screws. |
