Air flow & dam rings

Welding Alloys’ solution

Original parts supplied in a vertical mill do not have a long lifetime and have to be replaced, particularly once a wear pattern has been established as these parts will quickly deteriorate, leading to leakages through the mill body. To provide a solution for this, Welding Alloys has developed a special range of wear plates called Hardplate™ that can endure the working temperature and aggressive environment within the vertical mill. These wear plates can be supplied fabricated ready to fit, or as standard plates to protect the internal lining of the vertical mill.

Our process allows us to restore the geometry of air flow rings and dam rings back to their original dimensions which results in higher efficiency of the mill.

Benefits 

  • Greater production efficiency
  • Hardplate™ reduces the effects of abrasion due to hot gases and abrasive particles meaning it will achieve a longer service life.

Consistency and customer service

Welding Alloys joining wires, used for on-site installations, are designed to achieve the best results. These wires eliminate the normal weak points at intersections and joints, therefore the join will not wear before the plates.
