ABSTRACT:
A lubricating device for clay or ceramic extruders in the form of a separable lubricating ring inserted between the exit end of the extruder casing or barrel and the entrance end of the die. The lubricating ring includes an annular outer member having a substantially cylindrical inner wall. A frustoconical liner is affixed to the inner wall in such a manner as to form a reservoir therebetween and deliver a variably controlled supply of lubricant to the clay column at the entrance to the forming die. The frustoconical shape of the liner provides a negative angle of impingement between the clay and the lubricating ring resulting in longer life of the liner and an improved penetration of lubricant into the clay or ceramic material.
