Note:All of above information is for normal design, some important requirements from customer can be used on our tube mill line,for example,if customer need to use Siemens motor instead of hengli motor, and also need to change the bearings to NSK brand, we can do all of these as well if customer can bear the increased expense.

For tube mill, we have the strong capability to design and manufacturing according to client's individual requirements. The tube mills that are produced by "Nanyang" Company Ltd. have good quality, we believe our products are the No.1 in China industry.

Hope to be your faithful partner in the near future!!
