Wear resistance D-Parts for the Vertical Roller Machine (VRM)

[tintuc]

The Vertical Roller Mills (VRM) is a type of grinding machine for raw material processing and cement grinding in the cement manufacturing process in over the world.



 In Vietnam, VRM has been using in many cement plants and some thermal plants in particular. And it has been equipping more and more cement plants around the world because it brings many benefits on many sides in general.



(The history of VRM)



How does VRM Works?


VRM consists of some rollers and one table which is rotated by electric motor, and all of them work together for grinding raw material. 



In the very first beginning, raw materials are placed on the table. And the table begins to rotate, due to the action of centrifugal force of the rotation process, raw material automatically moves to surrounding area, enters grinding rollers slide(The gap between the rollers and the table's surface). Raw materials are crushed by extrusion, grinding and shearing. The rollers are driven by the friction between the table & raw materials. Due to such grinding, fine particles pass through the separator as the final product to the silo for the next process.



(Grinding process)



Even though there is only one working principle but each manufacturer would have different tech solutions for their own aim to optimize the grinding process, energy-efficient.



Some Famous VRM Manufacturers 





Why VRM needs to protecting by Wear resistance D-Parts


 Since in the heavy industry many pieces of equipment are frequently damaged because of having always been in impact, friction, abrasive condition. Especially, as you know the grinding process of VRM and even other processes are very harsh, any kind of equipment is also headed-on impact with raw materials which have sharp corners, even it has chemical compositions, heat erosion…

That's WHY D-Parts Wear resistance (Custom shapes unit from Chromium Carbide Overlay D-Plate) is one of the best solutions for repairs and extend the life of many types of equipment in VRM by protecting: hard carbide gives protection against wear, this wear being abraded in place of the core steel material of equipment.


  • Specifically designed and Available to form wear part in various shape
  • Outstanding wear-resistant property
  • Economical production cost
  • Impact resistance & Good temperature resistance
  • Good weldability to most structural steel
