Double deck screen DDRS is a type of screen that is used to separate fine and coarse pellets before entering the kiln. Corrosion of the surface of the roller screen by the input load causes the iron ore concentrate to stick to the surface of the roller blades, which reduces the external diameter, bending and mechanical problems of the double deck screen roller.
The main alloys used to make roller double deck screen can be called 304L plated steel.
The main feature of this device is smooth movement and maintaining the integrity of fragile particles. The roller screen also provides better performance, less noise, and can separate sticky materials with high moisture content. This machine is mainly used in iron ore processing plants for concentrate garbage collection before HPGR (high pressure roller mills), and pellet granulation after disc balling (pelletizer disc).
Asan Ro Lavin covers all the important parameters such as: the type of coating of the rollers and compliance with the smoothness of the surfaces, the lack of lameness and the balance of the rollers in all sizes, compliance with the welding type, etc.
Also, this company has the ability to produce roller screens up to 5.5 meters long.
