1. A continuous mill, comprising:
a casing (1) having a substantially cylindrical shape and rotating about an axis of rotation (X);
an inlet opening (2), concentric to the axis of rotation (X);
an inlet duct (20), connected to the inlet opening (2);
an outlet opening (3), concentric to the axis of rotation (X);
an outlet duct (30), connected to the outlet opening (3);
a bend (11), arranged along the outlet duct (30), which defines a curve of the outlet duct (30);
a regulator (12) associated with the bend (11) and predisposed for varying the position of the bend (11) so as to vary at least a height thereof;
wherein the continuous mill comprises a first aeration duct (21), connected to the inlet duct (20), and a second aeration duct (31), connected to the outlet duct (30), wherein the first and the second aeration ducts (21,31) are open to the atmosphere,
wherein the first aeration duct (21) is provided with a control valve and, at a first end, is connected to the inlet duct (20), while at a second end the first aeration duct is open, and
wherein the second aeration duct (31) is located upstream of the bend (11) and is provided with a control valve and, at a first end, is connected to the outlet duct (30), while at a second end the second aeration duct is open,
wherein the first and the second aeration ducts (21,31) are each provided with a level probe, predisposed for detecting a level of liquid inside the first and the second aeration ducts (21,31).
