At the beginning of 2015, Dawn's after-sales service team knew that the customer was planning to enlarge the scale of MTW175 coal grinding production line during revisiting the project. Later, our technological team negotiated with the customer in details. Connecting the existing production line to the demand on upgrading, we customized a scientific expansion scheme which won approval once more and customer reached consensus with us. Finally, the customer bought a set of LM130M Vertical Mill. This was the second cooperation after the customer bought our MTW175 mill in March, 2013.
