A crushing apparatus for crushing waste material, said apparatus comprising:
- a housing having a filling opening;
- a hollow rotary crushing drum within said housing, said crushing drum having a drum cavity and at least one open end, and said crushing drum being provided with peripheral cutting bars spaced apart by entry slots open into said drum cavity;
- a drive to rotate said crushing drum;
- and
