Modification of the TPA-220 Piercing Mill for Rolling ...

Before the modification, the maximum feed angle in the screw rolling mill with two barrel rolls was 9.5°. It was decided to carry out a low-cost modification (without replacement of the major parts of the drive) of the piercing mill at PNTZ Shop No. 1 to increase the feed angle to 11–13° and to reduce the amount of defects by, expectedly, 10–15% of the actual amount.

Roll Mill - an overview | ScienceDirect Topics

4.2.3.1.1 Roll Mills. The roll mill is the simplest batch mixing equipment. The principal design consists of two horizontal rolls, usually of equal size, arranged side by side and rotating toward each other at different speeds. The ratio of the peripheral speeds of the rolls, known as friction ratio, ranges from 1 to 2 but is usually around 1.2.

Roll changing on a rolling mill is speeded by a modification to the flat pin, fork-type, coupling. The lower prong of the fork is extended by the addn. of a lug, and the upper prong has a chamber between its inner and end surfaces. The difference in length between the inner faces of the upper and lower prongs is more than half the length of the square coupling block that fits between them.
