20140263781 | BONE MILL ASSEMBLY FOR USE WITH CORTICAL AND CANCELLOUS BONE - A bone mill assembly provides a drive motor with a reducer. The drive motor is connected to a non-rotating coupler which is connected to a main drive cutting head. A mill housing consists of a manual feed chute or a pneumatic feed chute that shuttles the bone stock onto the main drive cutting head of the mill. The bone stock is ground to a smaller particle size and then shuttled by rotation onto a straight secondary blade. This chops the particle size even smaller and then is sized by an internal window sieve. If the particle size is small enough, the bone particulate passes through the sieve into a collection pan. If the particle size is too large, it will then be rotated back up within the housing to be processed again by the main cutting head. Different sizes of the main cutting head are used for customer specific applications. | 09-18-2014 |
