Contents of the invention

The technical problem to be solved by the present invention is to provide a bone pulp machine with a wide application range.

In order to solve the above technical problems, the present invention provides a bone pulp machine, which includes a rolling filter assembly, a double output shaft motor, an extrusion assembly and a rotating assembly, and the double output shaft motor has a first output shaft and a second output shaft;

The rolling filter assembly includes a grinding cylinder, a push rod, a grinding disc and a grinding plate installed in the grinding cylinder, the grinding plate is fixed at the front of the inner chamber of the grinding cylinder, and there are several filter holes on the grinding plate. The grinding disc is correspondingly arranged on the rear side of the grinding plate, and the rear side of the grinding disc is fixedly connected with the front end of the push rod.
