A rotatable crusher wheel (22) is mounted in a housing (21) and receives pills via an opening (32). Rotation of the wheel (22) creates a crushing action on the pills, which is facilitated by projections on the wheel periphery and on the confronting internal walls (31) of the housing. The powder formed by the crushing action then falls into a receptacle (24) which can be detached for subsequent removal and use of the powder. The housing comprises two components (23, 24) which together define a bearing for an axle (27) of the wheel (22), the components being separable to allow insertion of the wheel during initial assembly of the device. |
