The Tandem Cold Rolling Mill is used mainly for breakdown rolling of thick sheets/ plates of metals like Copper, Brass and Aluminum where the weight of sheet is on the higher side. It is difficult to return such heavy sheets back to the operator after the pass so the Tandem Mill is advantageous in such scenario because it provides for reversible operation. The sheet can be fed in the mill from both sides thus reducing the handling time and effort. These mills consist of Top & Bottom Rolls of same diameter and one middle Roll of smaller diameter. The drive is give to both Top & Bottom Rolls through a combination of Gear Box — Pinion Stand — Coupling Spindles. Since the diameter of Work Roll is larger in this case, this mill is more suitable for rolling in thicker sheets.
