The test mill is a reduced-scale model of an industrial mill used in the mining industry and comprising a rotary shell (10) capable of rotating about its longitudinal and horizontal axis. This shell is capable of containing a certain amount of grinding media and of receiving a certain amount of material to be ground so as to be able to operate under conditions comparable with those of an industrial mill. The shell is divided, in the longitudinal direction, by a perforated transverse partition (24), into a grinding chamber (20) and a measurement chamber (22), the perforations in the partition being sized to hold the grinding charge back and allow the ground matter to pass through, whereas the shell (10) comprises a series of injectors (28) allowing fluid products to be injected into the grinding chamber (20). It is possible to make in-situ and continuous analyses of the pulp in the measurement chamber.
