double rods breakdown mill is widely be used to drawn  2 copper rods from 8.0 mm to 1.2-3.5 mm with online annealing, with the following advantages:

1. completely immersing lubricant, ensuring the wire cooling and lubircantion throughly

2. each drum is transmitted by single motor, the tensile rate can be adjustable

3. can realize fast die-changing 

4. can breakdown 2 rods at same time
