Abstract

Improvements in rotating ball or tubular mills of the type that comprise a hollow body supported by means of trunnions, characterized in that a deformable seal and assembly is provided in the mill's feeding area, comprising a rigid rim that has a inner circular hole intended to receive a supply duct and allow it to extend through it, and which determines an outer circumferential cavity, an elastomeric annular element of resistant material that determines a hollow annular chamber, equipped with an inner portion, adapted to be housed in said cavity, and of an outer cylindrical surface of a diameter approximately equal to that of the inner surface of the respective trunnion, and means to introduce a gas charge under pressure inside said element to expand it and locate said outer cylindrical surface in deformable sealing contact with the inner surface of said stump.
