Durston Double D4-158 Rolling Mill

This exceptional rolling mill has two sets of rolls, the top set for flat rolling and the bottom set grooved for square wire rolling. Both sets of rolls also have extension rollers. The top rolls incorporate four half rounds and the bottom rolls an additional three half rounds. The rolling mill is supplied with two turning levers. The first is used for heavy rolling, and this includes a gear reduction of 11-1. The second turning lever can be used for lighter rolling at twice the speed with a gear ratio of 5-1. Lever changeover takes only a few seconds. The top mill features an extra wide flat area of 158mm between two rollers with a diameter of 60 mm, each enabling a maximum roll thickness of 6 millimetres. The bottom mill has a total of 19 square wire grooves allowing wire rolling from 10mm to 1mm. The side extensions enable half round rolling of 8, 7, 6, 5, 4, 3, 2, and 1.5mm. Safety features include all gearing being covered with plastic housing. The mill itself is constructed from a single piece of cast iron to maximise rigidity and strength, and all rollers are induction hardened to 240 RC to ensure your rolls lasts a lifetime.
