Claim:
A granulator mill comprising: a mill housing including: one fixed part that is stationary arranged in a frame of the granulator mill and one openable part that is connected to the fixed part by a first pivot device with a first pivot axis which is substantially vertical in the normal position of use of the granulator mill; one rotor which is rotary inside the fixed part of the mill housing and includes a number of blades for co-operation with at least one fixed blade mounted in the mill housing; one discharge section whose interior is separated from the interior of the mill housing by a grid through which granulate passes from the mill housing to the discharge section; an infeed hopper on top of the mill housing, the infeed hopper being connected to the fixed part of the mill housing by a second pivot device with a second pivot axis which is substantially parallel to the rotational axis of the rotor and substantially orthogonal to the first pivot axis; and co-operating locking means on the openable part of the mill housing and on the infeed hopper, said locking means being configured to simultaneously contact and lock the infeed hopper and the openable part to the fixed part in a closed operational position, wherein the locking means is further configured to allow the infeed hopper to be pivoted to an open position thereby giving access to the interior of the mill housing only when the openable part of the mill housing is in open position.
