Abstract: An industrial mixing machine is disclosed for mixing material to be mixed in mixing containers that are open on the connection side and differ in at least one feature of their design, wherein one mixing container is attachable in each case to the mixing head of the mixing machine for mixing the material to be mixed contained therein, and wherein at least two mixing tools differing in at least one feature of their design are mountable on a mixing head of the mixing machine. The mixing machine has a detection device which is configured to determine whether the mixing tool currently mounted on the mixing head matches with the mixing container which is to be connected to the mixing head and in which the material to be mixed is located, and a safety device in communication with the detection device, which prevents the mixing tool and the mixing container opening from being brought together when the detection device detects that the mixing tool mounted on the mixing head does not match with the mixing container.
