Abstract: A crushing mill includes a crushing chamber and a feed unit to feed the waste to be crushed positioned upstream of the crushing chamber. Upstream of the feed unit a first aperture is positioned for the inlet of the waste to be treated in the feed unit and, downstream of the feed unit, a second transfer aperture is positioned to transfer the waste to be treated toward the crushing chamber. The feed unit includes a member rotatable around a determinate axis and provided with at least a pair of cylindrical sectors angularly offset with respect to the axis, provided with corresponding inlet and discharge apertures of the waste to be crushed and configured so that, in any loading and/or crushing step of the waste to be crushed in the crushing mill, they prevent the first and second apertures from coming into communication with each other.
